NTT and Tokyo Institute of Tech achieve 100 Gbps using terahertz band

NTT and Tokyo Institute of Technology have jointly developed an ultra high-speed IC for wireless front-end that operates on a terahertz frequency band, and in the 300 GHz band they have achieved a record 100 Gbps wireless transmission data rate.

The researchers implemented a mixer circuit that applied a unique proprietary high isolation design technology with an Indium phosphide high electron mobility transistor (InP-HEMT). NTT said this process enlarged the transmission bandwidth, which is a problem in the conventional 300 GHz band wireless front end. It also improved the signal-to-noise ratio (SNR). In addition, using this we realized a 300 GHz band wireless front-end module, and we achieved wireless transmission of 100 Gbps (gigabits per second).

NTT said future work will extend to multiple carriers by making use of the wide frequency band of 300 GHz band, and using spatial multiplexing technology such as MIMO and OAM. The researchers hope to produce an ultra high-speed IC that enables wireless transmission of 400 Gbos.

NTT employs Orbital Angular Momentum multiplexing for 100G wireless

NTT successfully demonstrated the first use of Orbital Angular Momentum (OAM) multiplexing to achieve 100 Gbps wireless transmission.

The laboratory tests combined OAM multiplexing with Multiple-Input Multiple-Output (MIMO) technology and carried the signals a distance of 10m.

NTT said a key feature of OAM is that electromagnetic waves can be superposed and separated because phase rotation occurs on the vertical plane in the propagation direction.  An electromagnetic wave with phase rotation cannot be received without a receiver having the same number of phase rotations at the time of transmission. NTT developed a transceiver operating in the 28 GHz band capable of OAM transmission. NTT also developed signal processing technology capable of handling 11 data signals simultaneously each at a bit rate of 7.2 to 10.8 Gbps, thereby achieving large-capacity wireless transmission at a total bit rate of 100 Gbps.

NTT believes the technology holds promise for achieving large-capacity wireless transmission at a level about 100 times that of LTE and Wi-Fi and about 5 times that of 5G.

NTT demos its photonic crystal fiber with high-powered lasers

NTT and Mitsubishi Heavy Industries (MHI) have demonstrated a kW class, high-power single-mode laser transmission over tens to hundreds of meters --
representing a breakthrough for laser processing technology.

The innovation leverages NTT's photonic crystal fibers (PCF) and MHI's high power laser processing technology.

NTT's photonic crystal fiber transmits light by using the confinement effect of air holes. PCF consists of silica glass and multiple air holes, and offers novel properties impossible with conventional optical fiber.

Laser processing requires the transmission of light whose power is more than 10,000 times that of conventional telecommunication light. However, maximizing the optical power and transmission distance encounters the physical limit created by optical nonlinearity. Applications include a range of infrastructure products, including in transportation, manufacturing, and precision cutting.

The achievement will be reported at the 89th lecture of Japan Laser Processing Society, which will be held at Suita Campus, Osaka University at 23-24 May 2018.

NTT develops new QoE technique in video streaming

Nippon Telegraph and Telephone (NTT) has demonstrated a video quality control technology based on Quality of Experience (QoE) in video streaming over mobile networks.

The QoE of video streaming to a mobile handset is evaluated by NTT's algorithm. Future communication quality is then predicted considering the user's environment. The algorithm optimally controls the bitrate in the midst of video streaming so as to achieve the preset QoE target.

NTT said its technology for video streaming enables maximum QoE, while reducing traffic over the network.

NTT develops realtime 4K high frame rate HEVC codec

NTT has developed a real–time 4K high frame rate HEVC codec for the live transmission of high frame rate (HFR) video. The codec doubles the frame rate of the standard video frame rate (SFR), from 50/60p to 100/120p.

NTT has demonstrated a 4K HFR HEVC encoder appliance and a 4K HFR HEVC decoder appliance, both of which are 1U size.

The 4K HFR HEVC encoder appliance provides backward compatibility by supporting temporal–scalable encoding, meaning the output stream can be decoded by conventional SFR decoder to yield 4K SFR video.

Moreover, our codec supports the MPEG Media Transport (MMT) protocol which enables hierarchical transmission. Two independent transmission routes can be used to transfer the base–layer data, which is used for decoding of 4K SFR video, and the enhancement–layer data, which is used together with base–layer data for decoding 4K HFR video.

NTT develops a better optical connector cleaner

NTT Advanced Technology (NTT-AT) has developed a new cleaner for waterproof optical connectors (ODC connectors), which are used in outdoor applications such as Fiber to the Antenna (FTTA) deployments.

The problem to be addressed is the contamination that builds over time on the end face of an optical connector, degrading reliability and performance. Optical cleaning tools can mitigate this issue.

NTT-AT's new "NEOCLEAN series" uses specialized microfibers that won't scratch the end face of the optical connector. Cleaning is performed with a simple push operation. One unit can be used for more than 400 cleanings.


NTT and Chunghwa Telecom advance their white box trial

NTT and Taiwan-based  Chunghwa Telecom have successfully carried out a joint experiment to verify the service continuity and reliability of a virtual network control system.

This experiment was enabled by the combination of NTT’s Multi-Service Fabric (MSF) and Chunghwa Telecom’s orchestrator (NAPA).

The experiment was performed on a network of whitebox switches. Specifically, virtual network configuration and control technologies using white-box switches and white-box switch operating systems were verified by controlling MSF from NAPA.

Broadband Forum targets PON Virtualization for 5G Fronthaul

The Broadband Forum and NTT are undertaking a project to standardize the virtualization of PON networks to support the delivery of Time Critical Applications (TCAs), such as 5G fronthaul.

The project, which was initiated by Forum member NTT, is called PON Abstraction Interface for TCAs. It looks at how SDN and NFV can be applied to Optical Line Terminals to disaggregate PON functions to functional modules with open interfaces. The first phase will define the disaggregation policy and functional requirements of interfaces to disaggregate PON functions which need time-critical processing, while the second phase will define the detailed specifications of the interfaces as Application Programming Interface (API) sets.

“As users’ usage changes, both in regard to the different services required and the amount of data coursing through fiber networks, operators need to update their PON networks, including by adding TCAs,” said Akihiro Otaka, Executive Manager at NTT Access Network Service Systems Laboratories. “This used to require the remake of PON equipment for each service, but should be done via a software upgrade in the near future to improve cost-effectiveness. With demand for this increasing, it is important we ensure there are standards in place to achieve a vendor-agnostic system and ensure mass deployment of this new system architecture, which is essential if we are to deliver agile and flexible next-generation broadband networks for emerging services.”

“As we work to meet the demand for new services, faster connectivity and more bandwidth, our focus is shifting from the fixed network to a holistic broadband network,” said Robin Mersh, CEO of Broadband Forum. “We know fiber will play a huge role in the delivery of 5G and this project looks to define that role and make it possible for operators to offer fronthaul services, among others, via their PON networks. This makes the work important not just for the broadband industry but the telecoms market as a whole and it can only be achieved on a wide scale through collaboration and standardization.”

NTT DoCoMo will lead in 5G

by James E. Carroll

From our 20-year archive of telecom news, we know that NTT DoCoMo announced the first 4G mobile network trial in 2003 at its R&D facilities in Yokosuka, Kanagawa Prefecture, Japan.  Seven years later, full-scale LTE trials were underway across the Tokyo metropolitan region.  On December 24, 2010, NTT DOCOMO officially launched its "Xi" LTE service across Japan, delivering peak theoretical speeds of 75 Mbps from some buildings and 37 Mbps peak speeds across much of its national network. In the first 18 months after the service launch, DOCOMO already had 5 million subscribers (Aug 2012). The service has been a clear customer favourite since then. The carrier likewise was among the earliest mobile operators to introduce flat-rate data plans, to introduce VoLTE service, and to adopt LTE-Advanced technologies.

Given Japan’s early-adopter status for technological innovations in general, and DOCOMO’s deep R&D programmes, the 5G wave quite likely will begin here.  DOCOMO has previously stated its intention to roll out commercial 5G services across Japan ahead of the 2020 Olympic Games in Tokyo. This is likely to mean a nationwide rollout of 5G, or at least major metropolitan areas across Honshu, and not just a small collection of 5G base stations in a single neighbourhood, as some other carriers will be tempted to do just to claim to be “first” in rolling out the next generation technology.
DOCOMO press machine is already ramping up with 5G announcements every month.


8K Video over 5G

Earlier in November, DOCOMO and Sharp demonstrated a 12-channel MMT (MPEG Media Transport) transmission of 8K video over 5G. The trial, which was conducted on November 1 at its DOCOMO’s Yokosuka R&D, was supported by the Japan Broadcasters Association, a big backer of 8K video encoding and MMT encoding. Each of the 12 channels required 80 Mbps. The companies reported the successful transmission of stable multi-channel 8K video with a high bit rate to multiple devices with the use of error detection and correction technology. Japan is likely to be an early adopter of 8K consumer video screens. DOCOMO’s 5G network may be a viable platform for this application.



5G for Vehicular Communications
DOCOMO is working with Toyota, Ericsson, and Intel to test 5G to vehicles in motion. Testing earlier this month at Japan’s National Museum of Emerging Science and Innovation (Miraikan) in Tokyo demonstrated data speeds of up to 1 Gbps for 4K-resolution video communications with a vehicle travelling at 30 km/h. 

For this set-up, the moving vehicle was equipped with an Intel GOT 5G Automotive Platform terminal and a compact on-board antenna head designed for connected car trials. DOCOMO’s 5G trial environment provided coverage over the nearby Odaiba area using three Ericsson base stations and Cloud-RAN. The vehicle successfully streamed live 4K video at data speeds of up to 1 Gbps downlink/600 Mbps uplink with low latency.

The NTT Group and Toyota continue to collaborate on 5G-connected cars. We will have to see how the technology performs at higher vehicular speeds and how the network performs when thousands of connected cars in the same area try to use the network simultaneously.



5G to Connected Vehicles with Digital Signage

A further refinement of 5G-to-the-vehicle is a project underway between DOCOMO and Sony. This concept involves a 4K digital signage system fitted to the outside of the New Concept Cart developed by Sony. The idea is for the vehicle to display a concept stream of advertising as it cruises down the street.

Presumably, the content would include live streaming, otherwise, local storage could ensure high-quality video replay without requiring a 5G network. However, we can see that DOCOMO is experimenting with new concepts to leverage 5G.



Testing MediaTek’s 5G Silicon

While we await a final 5G specification, some silicon vendors are rushing pre-commercial chipsets to market. DOCOMO is working with MediaTek on one such implementation.

MediaTek’s 5G chipset claims to increase the spectral efficiency of mobile devices by up to 2.3 times compared to existing LTE technology. The device integrates DOCOMO's non-orthogonal multiple access (NOMA) radio access technology with MediaTek's multi-user interference cancellation (MUIC) technology, which is required to achieve NOMA.


The idea with NOMA is to multiplex signals at a base-station transmitter to leverage the increased signal processing capacity of user devices and cancel interference among multiplexed user signals. MediaTek says its MUIC technology removes interference from other users when a base station transmits a signal to a number of users simultaneously. The silicon apparently is being developed for smartphones or other portable devices as an alternative to Qualcomm or Intel 5G modems.

In covering NTT DOCOMO’s race to 5G it is important to note that collaboration with other industry players is the name of the game.  As part of a mid-to-long-term strategy outlined in May, DOCOMO, which currently serves more than 70 million mobile customers in Japan, plans to launch “exciting and unexpected services” under a company-wide project called "empower+d challenge" (empowered challenge), which will “enable customers to realize their aspirations and achieve greater affluence.”

Through the creative application of virtual reality, artificial intelligence (AI) and IoT technologies, DOCOMO envisions that 5G will lead to new customer experiences, lifestyles and work styles.



Since early last year, DOCOMO has been an active member of the 5G Open Trial Specification Alliance, which has pushed for early 5G trial specifications across multiple spectrum bands, including bands above and below 6 GHz. Other founders of this group include KT, SK Telecom and Verizon. This work led to the inclusion of the first 3GPP 5G NR specification to be included in the upcoming Release 15 - the global 5G standard that will make use of both sub-6 GHz and mmWave spectrum bands.

Vendor collaboration with DOCOMO

Earlier this year, DOCOMO announced plans to conduct interoperability testing and over-the-air field trials in Japan based on the 5G New Radio (NR) specifications under development by 3GPP, specifically involving mid-band spectrum at 4.5 GHz and millimeter wave (mmWave) spectrum at 28 GHz. The trials were to be based on device prototype and base station solutions from Qualcomm Technologies and Ericsson, respectively.

Working with Huawei, DOCOMO recently conducted an outdoor 5G trial for ultra-reliable low-latency communications (URLLC) using a 4.5 GHz system. The trial featured a stationary mobile terminal that received signals at distances of 0.8 to 1 km from the base station. During the trial, DOCOMO achieved an over-the-air latency of less than one millisecond together with a packet transmission success rate of more than 99.999%.  Impressive performance results!

In June, DOCOMO confirmed the addition of Nokia to it 5G ecosystem. Nokia participated in a demonstration of low-latency 4K video streaming during a 5G Tokyo Bay Summit 2017 earlier in May. More broadly, the collaboration is also known to include the Intel 5G Mobile Trial Platform, will commence with the key interoperability testing of multi-vendor technology using the 4.5 GHz frequency band. 

Ongoing tests of the Nokia 5G FIRST solution include the Nokia AirScale base station transmitting over a 5G radio interface to the Intel 5G Mobile Trial Platform. The companies plan to test end-to-end applications over the air between the base station and the device on the 4.5 GHz frequency band, which is a candidate band for 5G services in Japan. The collaboration with NTT DOCOMO will specifically involve Nokia's AirScale Active Antenna equipped with massive MIMO technology and digital beamforming, designed to provide enhanced cell range, maximised performance at the cell edge and increased spectral efficiency. The 5G FIRST platform, designed to support multi-vendor end user devices for 5G, incorporates the Nokia AirScale base station and AirFrame data centre technology.

With Samsung Electronics Co., DOCOMO has demonstrated a 5G data speed of more than 2.5Gbps with a mobile device that was in a vehicle travelling 150km/h, sufficiently fast for connectivity onboard most trains. This trial took place in November 2016 at the Fuji Speedway in Shizuoka Prefecture, Japan. Transmissions were conducted using the 28GHz high-frequency band. The development work also featured massive multiple-input multiple-output (MIMO) technologies that incorporate beamforming.

Cisco is supplying its Network Services Orchestrator to help DOCOMO carry out network device provisioning and transform its service lifecycle. DOCOMO first deployed Cisco’s network functions virtualization (NFV) system in 2016.

Another one of DOCOMO’s 5G partners is Sumitomo Electric. Together, the companies are looking to 5G to power the real-time collection and delivery of traffic information using high-definition sensors. There are currently tests underway at an outdoor course within the Yokohama Works of Sumitomo Electric. Sensors are installed along the course and in vehicles. The vehicles are equipped with DOCOMO 5G terminals that communicate with DOCOMO 5G base stations throughout the facility. Traffic information is analyzed in real time and then fed back to drivers and pedestrians. Clearly, the aim is the smart city, where data from the public roadways can be analyzed and shared in near real-time. For a mobile operator such as DOCOMO, a successful business case and trial would mean millions of 5G endpoints with the municipal, provincial and perhaps national governments as potential long-term clients of the network – a fantastic underwriting opportunity for the new infrastructure if such a deal could be struck,

From the municipal 5G business case to the personal       

A few months back, NTT DOCOMO Ventures announced an equity investment in Petametrics, a San Francisco start-up that provides “LiftIgniter”, a personalization API to deliver a wholly unique experience to every individual user impression.

LiftIgniter was founded by Indraneel Mukherjee, a former Google researcher, and a team of machine learning and math PhDs., The personalization engine is powering various NTT DOCOMO e-commerce services. The idea here is to capture data points from consumers and then perform deep analysis to uncover macro trends. With LiftIgniter, the machine learning-based personalization algorithms run 24/7, learning and reacting to each impression in real-time to predict and serve up tailored content for every user touchpoint. The company says its platform is agnostic across all content, languages and devices. While not necessarily specific to 5G, the number of endpoints envisioned by these developers appears to be of high magnitude, meaning that is could be a very potent use case for 5G-enabled IoT.

NTT East implements Cisco NFV

Nippon Telegraph and Telephone East Corporation has adopted a full-stack, ETSI-compliant NFV solution validated and supported by Cisco for its new Maruraku Office service, which is aimed at small and medium enterprises and which consolidates Internet lines, firewalls, routers, storage and business phones in the cloud.

Specifically, NTT East deployed Cisco Network Services Orchestrator (NSO), Cisco Elastic Services Controller (ESC), and the Cisco Network Functions Virtualization Infrastructure (NFVI) solution, including Cisco Virtual Topology System (VTS) and Cisco Virtualized Infrastructure Manager (VIM).

Cisco to Automate NTT DOCOMO’s Network Device Provisioning


Cisco is supplying its Network Services Orchestrator to help NTT DOCOMO carry out network device provisioning and transform its service lifecycle. Cisco noted that DOCOMO deployed a network functions virtualization (NFV) system last year, but due to the complexity and time-consuming operations with network device provisioning, it has taken the initiative to fully improve its business efficiency by applying “automation” to various operations.

NTT develops a cooperative WLAN with distributed smart antenna

NTT has developed a technology its calling “cooperative wireless LAN with distributed smart antenna system (D-SAS)” to improve connectivity in high-density environments such as sports stadiums.

The technology consists of two key functions: one performs centralized radio resource management by taking information about the surrounding radio environment into consideration; the second optimizes parameters dynamically with the aid of the first function so that the interference is reduced at each AP.

NTT has tested the technology at NACK5 stadium in Omiya, Japan with the deployment of about 150 APs under stadium seats. All 11 channels available on the 5.47-5.725 GHz band (i.e., the W56 band) were used and the channel bandwidths of all APs were 20 MHz in both settings.

NTT said its testing showed that its cooperative wireless LAN technology with D-SAS achieved throughput twice than that obtained with the conventional technology.

NTT Group seeks growth through diversification – part 1

by James E. Carroll

The NTT Group ranks among the top carriers worldwide by nearly any metric, whether by revenue, subscribers, traffic, corporate debt, overseas investments or industry influence.  We know the acronym stands for Nippon Telegraph and Telephone Corporation, the incumbent telecom provider of Japan that still owns most of the last mile infrastructure of the company and is a leading innovator in optical and mobile networking technologies.  Recently, however, company executives, spelled out the acronym as follows:

Next value partner for
Transformation of business models and lifestyle by
Trusted Solutions of global, secure, end-to-end and full-line ICT services.

There are many key words in this new rendition of the company name but chief among them is “partner”. In its corporate strategy presentation, NTT executives now routinely emphasize the company’s willingness and ambition to seek partners both in Japan and abroad for the many opportunities it sees with artificial intelligence (AI), Big Data, telematics, IoT, entertainment, and even the management of modern sport stadiums.


NTT is certainly a big group. As of March 2017, it had 944 subsidiary companies and 274,850 employees.



Some current metrics on NTT and its User Base
In financial terms, the last quarterly report confirms that NTT continues to grow modestly. For Q2, operating revenues amounted to 2.809 billion yen, an increase of 93 billion yen over the same period in 2016, representing growth of 3.4% year over year. Net income amounted to 271.5 billion yen, up 11.4% year over year.

NTT Group’s highest growth rate occurred in its overseas operations. Overseas sales amounted to US$4.6 billion in Q2, up 21.2% year over year. Overseas operating income amounted to $0.19 billion, up 43% year over year.

NTT Group seeks growth through diversification – part 3

Preamble – The first part of this article presented an organizational look at the NTT Group, which consists of five main groups and an astounding number of subsidiary companies: 944 at last count with interests as diverse as IT outsourcing, mobile apps, real estate, data centers, finance, construction, and even electrical power. The second part of the article looked at NTT’s Global Cloud Business Promotion, which aims to provide full-stack, full-lifecycle integration from the data center, to the managed ICT layer, to the applications.

From its annual report, we know that the NTT Group currently generates about US$16.9 billion in overseas revenues, of which 65% is for IT infrastructure and 35% is for application services.  This breaks down as follows:

Americas         $5.9b, including 55% for IT infrastructure and 45% for applications
EMEA             $6.6b, including 60% for IT infrastructure and 40% for applications
APAC              $4.4b, including 90% for IT infrastructure and 10% for applications




NTT Communications

The network resides between the data center layer and the managed ICT solutions and it is here that NTT perhaps has its greatest strength. Inside Japan, NTT’s fiber infrastructure, through its various subsidiaries, is unrivaled for wholesale operations and FTTH residential connections. The global enterprise networking segment is addressed by NTT Communications.  The second part of this article covered the NTT Comm’s recent Global SD-WAN launch. The company is also well-known for its Global IP Network, which is IPv4/IPv6 backbone network connected through a single AS 2914 and offering high-speed, high-capacity IP communications to all major countries in Europe, North America, Oceania, and Asia. Alongside this IP backbone, NTT Comm operates a global MPLS service that delivers Layer 3 IP-based MPLS and Layer 2 Ethernet-based VPLS in 190 countries/regions.

More recently, NTT Com has developed a Multi-Cloud Connect service that is directly connected to public clouds hosted in key markets across Europe, North America and Asia Pacific. Multi-Cloud Connect currently connects to Oracle Cloud and other third-party cloud services including Amazon Web Services (AWS), Microsoft Azure, Office 365, Dynamics CRM Online, as well as NTT Com's private cloud service, via a security-enhanced, private Layer 3 connection, avoiding the public Internet.

NTT Comm is an active participant in the subsea space. One project it has led is the recently-completed, consortium-backed Asia Pacific Gateway (APG) optical submarine cable network, which spans a total length of 10,400 km and leverages 100 Gbps optical transmission and digital coherent technology to deliver a capacity of more than 54 Tbps, the highest of any network in Asia. NTT Com has established two diverse landing points, one in the East and the other in the West of Japan for the APG and Pacific Crossing-1 (PC-1) submarine cable which connects between Japan and the U.S. having diverse route such as north and south routes. The company has also implemented diverse landing points in Hong Kong and Singapore for the APG and for the Asia Submarine-Cable Express (ASE), which was launched in August 2012.

It should also be noted that NTT Comm, like other companies in the group, sometimes deploys proprietary technologies developed in-house. Earlier this year, NTT Communications began deploying a 400 Gbps optical transmission system in its data centers. The system raises the transmission capacity of NTT Com's core network above 19Tbps per optical fiber, or more than double existing capacity. The company said the 400G rate is achieved by using advanced digital-signal processing technology developed in house.

Connecting the pieces - Dimension Data

Dimension Data, which was founded in 1983, is probably the best-known technology firm from South Africa having built a global reputation for excellence in networking integration, IT management and data centers. Over the years, Dimension Data expanded into markets worldwide, sometimes acquiring local integration companies, including Australia's ComTech. Dimension Data has also served as Cisco Systems exclusive distributor in South Africa. The company reports an annual turnover of US$7.5 billion. It now has offices in 52 countries and 30,000 employees, 

In 2010, the NTT Group acquired Dimension Data for £2.1 billion ($3.2 billion). Since then, NTT has preserved Dimension Data as an independent subsidiary. Dimension Data still maintains its headquarters in Johannesburg with mostly local management. Jeremy Ord, who served as Managing Director since its inception, continues on as Executive Chairman. In 2016, Dimension Data appointed Jason Goodall as Group Chief Executive Officer. Goodall previously served as Dimension Data's Group COO, where he has been responsible for the regions and several global functions including sales, marketing, Group Information Services (GIS), HR and commercial finance. Goodall is a veteran of Dimension Data having served many roles during his 18-year career with the company. 
Even while under the NTT umbrella, Dimension Data has persevered in its strategy of acquiring other integration companies to add to its team and customer base.

NTT Data

The NTT Group has another global IT integration and management company.  NTT Data, which was founded in 1967 and is based in Tokyo, maintains business operations in 42 countries. For 2016, NTT Data posted annual revenue of US$14.6 billion. It currently has about 120,000 employees. Unlike Dimension Data, which is a fully-owned subsidiary, the NTT Group holds a 54% equity stake in NTT Data. 

(NTT Comware is another IT integration subsidiary, although its operations are focused on the physical assets of the NTT Group itself rather than outside customers)

Overseas acquisitions are also a key element of NTT Data's strategy in Europe, the United States and APAC. In 2016, NTT DATA acquired Dell Services, an IT services provider recognized for its depth in vertical industries and for its offerings around infrastructure services, cloud services, application services, and business process outsourcing. The purchase price was reported at $3.05 billion. This deal significantly increased NTT DATA’s presence in North America particularly in healthcare and insurance industries. Prior to 2009, the Dell Services groups was known as Perot Systems, a business consultancy founded by H. Ross Perot.

Both NTT Group and Dimension Data identify digital transformation as a key business opportunity. Enterprise companies are under pressure to evolve their IT infrastructure or be crushed by more agile competitors. A big part of this revolves around process automation and finding cloud-optimised software that streamlines operations. Hybrid public/private infrastructure is required as is expertise in rapidly evolving open source technologies, such as blockchain. It is here that theses sister companies provide overlapping services and both have access to NTT Group's vast resources.

For example, earlier this year, Dimension Data and NTT Com agreed to explore how to deliver a unified cloud experience to clients through greater collaboration within NTT, initially via closer integration of the Dimension Data and NTT Com cloud IaaS platforms.

NTT demos 118 Tbit/s transmission on multi-core fibre

NTT, together with six partners, KDDI Research, Sumitomo Electric Industries, Fujikura, Furukawa Electric, NEC and Chiba Institute of Technology (CIT), announced a demonstration of what is claimed as the highest transmission capacity of 118.5 Tbit/s using a multi-core fibre with four optical paths within the same diameter as currently used fibre.

NTT noted that a conventional glass diameter of 125 µm in accordance with the international standard enables the use of existing fibre fabrication and optical connector technologies. The demonstration is designed to validate the concept of multi-core fibre-based long-haul and high capacity transmission system comprising multiple vendor technologies and advance the application of multi-core fibre technology.

In the new fibre, 4-5 cores can be arranged within a 125 µm diameter while maintaining the same transmission quality as current optical fibre, with a 316 km multi-core transmission line realised with a 0.21 dB/km average loss, concatenating standard diameter multi-core fibre with 4 cores fabricated by multiple vendors.

As part of the new design, Sumitomo Electric, Fujikura and Furukawa each fabricated a multi-core fibre with 4 cores and more than 100 km length. All multi-core fibres can be used in the 1260 to 1625 nm wavelength region and provide similar transmission properties to current SMF with mode filed diameter at 1550 nm of 9-10 µm).

The fabricated multi-core fibres were divided into a 20-40 km sections and three transmission spans with a length of 104-107 km were re-constructed by splicing the multi-core fibres provided by different vendors. A satisfactory low loss comparable to conventional SMF was achieved, with average loss of four cores in each span 0.22 dB/km or less, including splicing losses.

In addition, three multi-core optical amplifiers fabricated by NEC, KDDI Research, NTT and Furukawa were inserted at each end of three spans to compensate the signal attenuation. Cladding pumping type multi-core optical amplifiers designed to reduce power consumption were used, enabling a 16% improvement in power usage.

To confirm the performance of the constructed multi-core transmission line to beyond 100 Tbit/s transmission, 16QAM-based 116-wavelength signals were prepared and the output signal quality over 316 km transmission was examined.

Additionally, Fan-In/Fan-Out devices developed by NTT and Furukawa were used to input/output signals to and from each core of the multi-core fibre. Pluggable optical connectors with existing MU-type or SC-type interfaces from CIT and NTT were used to connect the input/output end of the multi-core transmission lines and Fan-In/Fan-Out devices.

The work was partially based on work commissioned by the National Institute of Information and Communications Technology (NICT), and the companies stated that they aim to introduce the standard diameter multi-core fibre by the early 2020s. The achievement was reported in early August as a post deadline paper at the Opto Electronics and Communications Conference (OECC 2017) in Singapore.
