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.

NTT Com to Deploy 400G in Data Centers

NTT Communications will begin deploying a 400 Gbps optical transmission system in its data centers beginning this month.

The system will raise 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.

The main features and advantages of the 400G system are as follows:

  • Top-level energy and space savings
  • The new system reduces energy consumption per bps by 75% and space requirements by 80% compared to the existing system. The savings were achieved through a synergistic combination of advanced digital-signal processing technology and 16nm complementary metal-oxide semiconductor (CMOS) technology. Energy-saving integrated circuits can be constructed rapidly, enabling transmitters to be quickly deployed even in confined spaces at data centers.
  • More than double existing transmission capacity
  • The new system achieves more than double the transmission capacity per optical fiber compared to its predecessor system. To generate 400G signals, the system utilizes NTT's 16 quadrature amplitude modulation (QAM) for both phase and amplitude, and sub-carrier multiple transmission.
  • New OTN and 400GbE interfaces

In connection with the deployment, NTT Com will offer new optional network services for enterprises, including the sequential launch of OTN interfaces (OTU2, OTU2e and OTU4) mainly for wholesalers and data center users, and a 400GbE interface incorporating framing technology compatible with OTUCn which is the result from NTT's R&D.

To deliver new services and functions with even greater speed and flexibility, NTT Com will combine SDN technologies and dis-aggregation architecture, which can be redeployed as required according to function or module, replacing existing high-function, all-in-one dedicated equipment.

NTT Carriers One Petabit per Second over Single Fiber over 200 km

NTT has demonstrated a record inline optical amplified transmission of 1 petabit (1000 terabit) per second over a 205.6 km single strand of 32-core (light paths) optical fiber.

The experimental system used 32-core fiber with a new arrangement of cores to reduce inter-core light leakage, a fan-in/fan-out (FI/FO) device to couple light into the multi-core fiber, along with new digital coherent optical transmission technology. The result aws 31.3 Tbit/s capacity per core (680 Gbit/s per wavelength x 46 wavelength channels).  Multiplied by 32 cores, adn the total transmission capacity exceeded the petabit milestone.

The test was conducted in collaboration with the Technical University of Denmark, Fujikura Ltd., Hokkaido University, the University of Southampton and Coriant.

The transmission occurred within a single optical amplifier bandwidth (C-band), which is half the bandwidth used in a previous experiment the used C-band + L-band. NTT said its research indicates that it is potentially possible to carry 1 petabit per second over 1000 km, which is approximately the distance between major cities both in Japan and in Europe.

SoftBank and Ericsson Test mmWave 28 GHz for 5G

Ericsson and SoftBank announced the next stage of joint 5G technology trials as part of a program launched in August last year, when the partners tested 5G technology including base stations and end user equipment with control signal feedback using mid-band spectrum at 4.5 GHz, which is one of the candidate bands for delivery of 5G services in Japan.

Following the completion of basic 5G trials conducted in Tokyo in 2016 using 4.5 GHz and 15 GHz spectrum, the two companies now plan to proceed with more advanced tests.

The next 5G trial will be conducted in both indoor and outdoor trial environments and will encompass device mobility and stationary testing. The trial will specifically utilise Ericsson's mmWave 28 GHz 5G test bed solution, which includes base stations and device prototypes, and will feature advanced 5G technologies including massive-MIMO, massive beamforming, distributed MIMO, multi-user MIMO and beam tracking.

The latest technology trials are designed to deliver both the multi-gigabit data rates and ultra-low latency that are expected to be key requirements for future consumer mobile broadband and industrial use-cases.

Ericsson announced last July that it was extending its longstanding partnership with SoftBank and would hold joint field trials of 5G technology in Tokyo. Under the agreement, the two companies planned to cooperate to build a common understanding of 5G use cases and deployment scenarios, evaluate potential 5G technology components in field trials, and collaborate on 5G research projects.

In November 2016, Ericsson announced it had completed the first commercial implementation of its Elastic RAN for SoftBank's in Japan. Part of the Ericsson Cloud RAN solution, Elastic RAN is designed to improve users' mobile broadband experience through dynamic coordination of users and cells. Ericsson stated that installation of the technology in a Tokyo train station showed that downlink throughput could be increased by up to 40% during peak hours for commuters with 3 carrier aggregation-enabled smartphones.

In February this year, SoftBank announced it had deployed Ericsson's virtual Mobility Management Entity (MME), Cloud Execution Environment (CEE) based on OpenStack and Cloud Manager for Orchestration (ECM) into its commercial network. The deployment implemented a complete network functions virtualisation (NFV) solution, including virtual network functions (VNF), NFV Infrastructure (NFVI), VNF Manager (VNFM) and VNF Orchestration (VNFO).

The Ericsson virtual MME operates on commercial off-the-shelf hardware and is designed to coexist with native Ericsson MME to extend the resource pool.
