ADVA Demos PAM4 100G Direct Detect with Corning SMF-28

ADVA Optical Networking and Corning demonstrated a 100 Gbit/s direct detect solution based on PAM4 technology using the newly expanded ADVA FSP 3000 CloudConnect platform and Corning SMF-28 ULL fibre. The demo showed how direct detect signals can be transported over 100 km while adhering to stringent optical signal-to-noise ratio (OSNR) requirements.

ADVA noted that through extending the reach of direct detect signals, ICPs and CNPs can use the technology to cost-effectively address DCI bottlenecks as well as to enable the relocation data centres to lower cost locations.

The joint demonstration specifically used ADVA's recently announced direct detect optical layer, featuring its new SmartAmp and PAM4 technology, which is designed to provide ICPs and CNPs with an open and cost-effective DCI solution that is lower cost than alternative coherent options.

By combining Corning's ITU-T G.652-compliant SMF-28 ULL fibre with the ADVA FSP 3000 CloudConnect it is possible to extend the reach of PAM4 direct detect transmission beyond 100 km, leveraging the ultra-low loss performance of the fibre. Corning's SMF-28 ULL fibre, typically delivering performance of ≤0.16 dB/km at 1550 nm, is claimed to offer the lowest attenuation of any terrestrial fibre, which helps enable enhanced OSNR across greater distances than previously attainable.

In addition, ADVA 100 Gbit/s direct detection solution, integrated with the FSP 3000 CloudConnect DCI platform, is designed to provide error-free transmission at a lower cost per bit than coherent solutions.

In a separate demonstration, ADVA partnered with Inphi to show how disaggregated direct detect technology can be used to develop flexible 100 Gbit/s transport systems. The demonstration involved its FSP 3000 CloudConnect equipped with direct detect OLS with SmartAmp technology and Inphi's ColorZ 100 Gbit/s PAM4 solution in a QSFP form factor. The demonstration showed transport 3.6 Tbit/s of bidirectional data across 80 km of fibre.

Regarding the demonstration, Dr. Bernhard Deutsch, VP, PLM, optical fibre and cable at Corning Optical Communications, said, "Corning SMF-28 ULL fibre provides more than a 3 dB improvement in loss budget over 100 km compared to a link constructed with generic single-mode fibre… this enables a practical DCI link with workable margin to be installed over longer distances, interconnecting data centres spread over a larger territory".

OFS Carries 200G over 4,500 km with TeraWave Fiber

OFS, a designer, manufacturer and supplier of fibre optic network products and solutions, announced it is showcasing the capacity and un-regenerated reach of Nokia's 1830 Photonic Service Switch (PSS) C+L-band DWDM system over OFS TeraWave ULL fibre, enabling reduced cost-per-bit of transport across the ultra-long haul distances between hyper-scale data centres.

TeraWave ULL fibre is claimed to offer the largest available effective area for a terrestrial fibre, thereby allowing improved suppression of non-linear penalties that limit the reach of high capacity, coherent modulation formats. The company also claims that the cost-per-bit of fully lighting a TeraWave ULL fibre can be up to 50% less than that of a G.652 fibre through avoiding the need for regeneration.

The Nokia 1830 PSS networking platform is designed to support ultra-long haul performance at 200 Gbit/s using the 8QAM modulation format, and extended metro/DCI reach with high spectral efficiency. The OFS TeraWave ULL ITU-T G.654.E fibre is designed to reduce amplifier noise leveraging low nominal loss of 0.168 dB/km and to minimise non-linear distortion via its large effective area of 125 microns squared.

OFS noted that the waveguide of TeraWave ULL fibre was designed to minimise both micro- and macro-bending losses in the L-band to enable enhanced terrestrial cable performance and superior splice performance.

For extended reach metro/DCI applications, the TeraWave ULL fibre can support 400 Gbit/s capacity over up to 300 km with 100 km spans without the need for Raman amplification when used with the Nokia 1830 platform. When combined with a hybrid Raman-EDFA amplifier, the fibre can support up to 200 Gbit/s transport over distances of up to 4,500 km un-regenerated with 100 km spans.

Commenting on the demonstration, Robert Lingle, Jr., director, market and technology strategy at OFS, said, "Traffic is growing inside the networks of cloud content providers at CAGRs up to 50%, while the distance between web-scale data centres can be over 4,000 km in Europe and North America… as practical and fundamental limits make it more difficult to increase spectral efficiency in the future, C+L-band transmission (can)… double the capacity per fibre if the fibre and cable are designed for L-band wavelengths".

Nokia and Facebook Test Trans-Atlantic Optimization

Nokia and Facebook announced they have collaborated on field trials of new optical digital signal processing technologies over a 5,500 km trans-Atlantic link between New York and Ireland.

To help address increasing demand for capacity on subsea fibre networks, Nokia and Facebook tested Nokia Bell Labs' new probabilistic constellation shaping (PCS) technology. The companies stated that the trial achieved an increase of almost 2.5x in capacity compared with the stated transmission capacity of the system, demonstrating the feasibility of using the technology across a real-world optical network.

PCS, a field of research at Nokia Bell Labs, is an advanced technique that utilises 'shaped' QAM formats to flexibly adjust transmission capacity to close to the physical limits, the Shannon limit, of a given fibre-optic link. Believed to be a first-of-its-kind experiment conducted on an installed submarine link, the test was conceived and planned by Facebook,

Nokia noted that PCS is based on 64QAM and, combined with digital nonlinearity compensation and low-linewidth lasers, enabled a claimed record spectral efficiency of 7.46 b/s/Hz, indicating the potential to upgrade this cable to 32 Tbit/s per fibre in the future. The test also included round-trip submarine transmission over 11,000 km using 'shaped' 64QAM with spectral efficiency of 5.68 b/s/Hz.

During the trial transmission tests based on the commercially available Nokia Photonic Service Engine 2 (PSE-2) validated the transmission of 8QAM wavelengths running at 200 Gbit/s and 16QAM wavelengths running at 250 Gbit/s, which is believed to be a first for trans-Atlantic transmission. The 200 Gbit/s 8QAM wavelengths supported a spectral efficiency of 4 b/s/Hz while also exhibiting sufficient performance margin for commercial operation.

Nokia and Facebook stated that the results of the trial will be presented in a post-deadline paper at the OFC 2017.

Finisar Shows 400, 200 and 100G Pluggables

Finisar, a major supplier of subsystems and components for fibre optic communications, announced multiple optics product and technology demonstrations at OFC, including new 400 Gbit/s CFP8 FR8 and LR8 transceiver, 200 Gbit/s QSFP56 FR4 and LR4 transceiver and a 100 Gbit/s QSFP28 eSR4 extended reach transceiver modules.

The company will also demonstrate its new Flexgrid single low-profile wavelength selective switch (WSS) for next generation ROADM subsystems during the OFC event.

400 Gbit/s CFP8 FR8 and LR8 transceivers

Finisar will hold multiple demonstrations of its MSA-compliant 400 Gbit/s CFP8 transceiver, enabled by 50 Gbit/s PAM4 technology. The CFP8 module family includes an FR8 version supporting 2 km reach and an LR8 version for 10 km reach, both operating over single mode fibre. The modules are designed for applications in router-to-router and router-to-transport client interfaces.

At OFC, optical cables will link a number of booths to create a network of systems and test equipment platforms to demonstrate error-free live traffic transmission at 400 Gbit/s using working Finisar CFP8 modules.

200 Gbit/s QSFP56 LR4 transceiver

Finisar's new 200 Gbit/s QSFP56 optical module is an evolution of the four lane QSFP+ form factor designed for hyperscale data centre and high performance computing (HPC) environments. The 200 Gbit/s QSFP56 family initially includes an FR4 version for 2 km and an LR4 version for 10 km reach over single mode fibre. The module utilises 4 x 50 Gbit/s PAM4 electrical and optical interfaces and is designed to work with next generation of switching silicon to enable 6.4 Tbit/s in a 1 RU configuration.

The demonstration at OFC will feature an LR4 module designed for 10 km reach as per the IEEE 200GBASE-LR4 standard.

100 Gbit/s QSFP28 eSR4 transceiver

Finisar's latest 100 Gbit/s QSFP28 extended SR4 (eSR4) module offers long reach over multimode fibre (MMF) and targets enterprises and large data centre applications. Finisar noted that IEEE 100GBASE-SR4 species 70 metres over OM3 fibre or 100 metres over OM4 fibre; the new QSFP28 eSR4 module enables 300 metres over OM3 fibre and 400 metres over OM4 fibre to address typical 10 and 40 Gbit/s applications.

The extended reach capability allows data centres and enterprises with installed multimode fibre to use existing fibre plant to upgrade to 100 Gbit/s. The product employs parallel optics and can interoperate in a fan-out configuration with four of Finisar's 25 Gbit/s SFP28 eSR transceivers. A demonstration will show two Finisar 100 Gbit/s QSFP28 eSR4 transceivers connected over 300 metres of OM3 fibre, with traffic generated and measured by an Anritsu MT1100A network master flex.

Flexgrid single low profile WSS

The new single low profile WSS, designed for single-slot ROADM line cards, expands Finisar's portfolio of WSS based on its Flexgrid and LCoS technology. The ITU Flexible Grid-compliant device enables dynamic deployment of bandwidth at 6.25 GHz spectral width and intra-channel attenuation control to enhance performance over an optical link.

The WSS is offered in configurations from 1 x 2 to 1 x 9 and supports next generation express and colourless/directionless add/drop architectures. The OFC demonstration will feature a 1 x 9 WSS configured to switch a mix of transceiver and ASE inputs to a common output port.

Oclaro Announces 1 Tbit/s Dual Wavelength PM-QMZ External Modulator

Oclaro announced that it has expanded its lithium niobate (LiNbO3) portfolio with a dual wavelength PM-QMZ external modulator for data rates up to 1 Tbit/s and that at OFC it is hosting an interoperability demonstration showcasing a 100 Gbit/s ER4-Lite QSFP28 and CFP2 over 40 km single-mode optical fibre (SMF).

New PM-QMZ modulator

The new dual wavelength PM-QMZ modulator joins Oclaro's established high-bandwidth single carrier PM-QMZ (polarisation multiplexed quad parallel Mach-Zehnder) modulator line that was launched in 2015 and has been tested in labs and R&D centres operating at symbol rates up to 64 Gbaud and with different modulation formats up to 128QAM.

Oclaro's dual wavelength PM-QMZ LiNbO3 external modulator is designed to support data rates up to 1 Tbit/s utilising two wavelengths 'packed' into a single gold box. The modulator is a high electro-optic bandwidth PM-QMZ device that integrates into a hermetic package two PM-QMZ sets, each featuring an input beam splitter, four parallel Mach-Zehnder modulators configured for I-Q modulation, a polarisation combiner and monitor photodiodes for power and bias control.

Key features of the new product include: 3 dB electro-optic bandwidth exceeding 28 GHz; smooth optical response up to 45 GHz, enabling symbol rates up to 45 Gbaud; extinction ratio above 25 dB for complex modulation formats; insertion loss below 12 dB; and support for L-Band operation.

Interoperability demonstration

The demonstration of 100 Gbit/s ER4-Lite QSFP28 and CFP2 over 40 km single-mode fibre (SMF) is designed to show how ER4-Lite solutions can deliver the low power and low cost required to enable 100 Gbit/s in the access and core networks where longer reach is required.

Oclaro noted that as 100 Gbit/s technology is deployed in metro and access networks, operators require 100 Gbit/s client interfaces able to provide 40 km reach without the use of amplifiers. The new ER4-Lite specification is designed to enable cost-effective 100 Gbit/s 40 km pluggable solutions in compact QSFP28 transceivers with FEC and APD-based receivers.

The new Oclaro QSFP28 ER4-Lite device, which complements the existing CFP2 product, leverages the company's proven 28 Gbit/s EML as used in its CFPx and QSFP28 LR4 product families. The ER4-Lite QSFP28, which is currently sampling, can support 100 Gigabit Ethernet and OTU4 applications with up to 40 km reach with FEC, or 30 km without FEC, and is interoperable with existing ER4 solutions up to 30 km.

Oclaro noted that QSFP28 has been standardised by ITU-T as G.959.1 4L1-9D1F and is being standardised by the newly established 4-Wavelength WDM MSA group.

Corning and Kaiam Demo CoPPhI

Kaiam, a privately-held developer of hybrid photonic integrated circuit (PIC) technology, and Corning announced they are showcasing an optical engine and single-mode fibre interface connector designed to be co-packaged with a 12.8 Tbit/s switch chip at the 2017 OFC in Los Angeles.

The companies stated that by converting high-speed signals to optical within the switch package, the high-density engine based on co-packaged photonic interconnect (CoPPhI) technology can potentially enable up to a halving in chip interconnect power consumption.

Kaiam noted that prior to CoPPhI, the sub-micron alignment tolerances required in single-mode optical packaging presented a barrier to creating practical co-packaged single-mode optical interconnect solutions, while the reduced power consumption provided by CoPPhI-enabled switches can address a key impediment to data centre growth.

At OFC, the demonstration by Corning and Kaiam features a prototype connector, with the optics capable of delivering 1.6 Tbit/s from four fibres at 400 Gbit/s per fibre, or lambda (4 λ), extendable to 8 λ. The demonstration interoperates at 25 Gbit/s per λ with a standard CWDM4 transceiver.

It was noted that multiple CoPPhI engines can be co-packaged in close proximity to the four sides of a switch ASIC to support over 12 Tbit/s of optical connectivity. Single-mode fibres interface to the engine via a low-profile connector compatible with electronic packaging and assembly processes, including solder reflow.

With the 12.8 Tbit/s switch IC generation, the companies stated that the power required to drive signals over a PCB between the switch IC and the optical module will equal the power required for the switching function. By shrinking the optics and pushing the electrical-optical conversion point close to the switch IC, the required line drive power can be minimised.

Separately, Kaiam announced that it plans to acquire the manufacturing facilities of Compound Photonics (CP) in Newton Aycliffe in the UK through a transaction hat includes investment by CP into Kaiam to develop the facility. Subject to final approvals, the agreement is expected to close in the second quarter.

The manufacturing space acquired through the deal will enable expansion of Kaiam's datacom transceiver manufacturing capacity and also includes a cleanroom for processing of III-V devices, including pHEMTs, HBTs, photodetectors and lasers. Kaiam noted that the new facility will advance its strategy of vertical integration.

Previously, Kaiam acquired Gemfire, its strategic PLC supplier, in 2013 and currently operates an 8 inch silica-on-silicon line for the fabrication of integrated optical components in Gemfire's Livingston facility in Scotland. It also operates 40 and 100 Gbit/s optical packaging lines at the facility that are nearing capacity due to rising demand.

The new facility in Newton Aycliffe and its wafer-fab will allow Kaiam to expand its silica-on-silicon and transceiver manufacturing and in the future enable it to add integrated InP photonic integrated circuits (PICs) for advanced transceivers.

Regarding the joint solution with Corning, Rob Kalman, Kaiam VP of marketing, said, "On-board optics such as COBO allow the industry to explore post-pluggable usage models but still require power-hungry electrical interfaces… Kaiam is working on the part of the problem that eliminates this power while also addressing the cost and density needs of hyperscale data centre customers".

Telia Carrier Tests TIP's Voyager Platform with Coriant

Telia Carrier, the wholesale carrier division of Sweden-based Telia, announced that the Telecom Infra Project (TIP) and Facebook have completed a trial of 100 and 200 Gbit/s transmission utilising Voyager equipment and technology developed by Coriant over its 1,089 km Stockholm to Hamburg route.

Telia Carrier stated that a key feature of the trial was the demonstration of the ability to effectively implement 16QAM signalling over long distances. Facebook has contributed Voyager, a whitebox transponder and routing solution that is being made available to the Telecom Infra Project (TIP) with the aim of enabling more open networks and a more connected world.

The company noted that the TIP aim of bringing a new approach to building and deploying telecom networks aligns with its own Carrier Declarations program, designed to help Telia Carrier expand and develop its network organically and be a leader in industry innovation.

For the trial, Telia Company, the parent company of Telia Carrier and a TIP member, supported Telia Carrier in conducting the test of the Voyager solution and has shared the results of the trial with other member companies. Carried out in early March, the trial demonstrated that decoupled DWDM transponder systems can offer a low cost, low power option, while also providing the necessary flexibility and accessibility to allow service providers to implement them within existing networks.

Following the trial, Telia Carrier is working with TIP, Facebook and Coriant towards the objective of disaggregating the hardware and software components of the network stack as part of the wider effort to make connectivity available to all.

Facebook unveiled Voyager at the TIP Summit last November and contributed the design to the TIP community. Recently, TIP cited forthcoming trial deployments of the solution by Telia, and noted that Orange was working with Facebook and the TIP Open Optical Pack Transport project group to evaluate the solution

When it introduced the platform in November, TIP stated that Equinix had tested Voyager with Lumentum's open line system over 140 km of production fibre, and that MTN had shared the results of a test of Voyager over its production network in South Africa. In addition, it was noted that Facebook, Acacia Communications, Broadcom, Celestica, Lumentum and Snaproute would deliver a disaggregated hardware and software optical networking platform, while ADVA was providing support for the solution.

Sprint Teams with Qualcomm, Motorola to launch Gigabit-class LTE

Sprint, which serves nearly 60 million connections in the U.S., together with partners Qualcomm Technologies and Motorola Mobility, a Lenovo company, have announced the debut of what they claims is the first U.S. deployment of Gigabit-class LTE on a commercial network using a forthcoming flagship smartphone.

The new gigabit class LTE service from Sprint employs three-channel carrier aggregation (CA) and 60 MHz of 2.5 GHz spectrum in combination with 4 x 4 MIMO and 256QAM higher order modulation technology to deliver Category 16 LTE download data speeds on a TDD network.

As part of the launch, Motorola showcased the high-bandwidth capability of its forthcoming smartphone that is based on the Qualcomm Snapdragon 835 mobile platform with an integrated Snapdragon X16 LTE modem to enable support for gigabit LTE capability.

Sprint stated that it plans to utilise its 2.5 GHz spectrum to offer gigabit LTE service in high-traffic locations across the U.S. as part of its strategy to provide a foundation for 5G by 'densifying' its network via the addition of small cells and smart antennas. The strategy is intended to enable Sprint to offer 5G-like services with gigabit-level performance over its LTE Plus network and to meet future demand for mobile broadband services.

Sprint claims that with 204 MHz of spectrum in the U.S. and more than 160 MHz of 2.5 GHz spectrum in the top 100 markets nationwide, it holds more licensed spectrum capacity to support gigabit-class LTE than any other U.S. carrier. In addition, it noted that licensed spectrum enables a more reliable and higher quality service for LTE Plus customers through not relying on unlicensed resources.

The roll-out of Sprint's gigabit class LTE over the LTE Plus network will require a series of incremental upgrades, starting with three-channel CA, which is currently available in over 100 markets. The next stage will be implementation of Category 16 devices enabling support for 4 x 4 MIMO and 256QAM.

Sprint also plans to utilise Massive MIMO, a key element of 5G, to further enhance capacity and coverage for its 2.5 GHz TDD-LTE spectrum. Leveraging massive MIMO radios using 64T64R, Sprint expects to be able to increase capacity to beyond the 1 Gbit/s rate and deliver capacity of 3 to 6 Gbit/s per sector.

Sprint noted that working with Ericsson, at MWC 2017 it demonstrated 1 Gbit/s performance over 60 MHz of 2.5 GHz spectrum, while in collaboration with Nokia it demonstrated how massive MIMO can be used to increase cell capacity up to 8x compared to 4G LTE using 2.5 GHz TDD-LTE spectrum with 64T64R.

Andorra Telecom selects Huawei to upgrade to GPON

Huawei announced that Andorra Telecom has selected it as the sole vendor for the FTTH project designed to provide ultra-high speed Internet access service to end users through an upgrade of the existing FTTH network, with deployments scheduled to start in March this year and completion due around January 2018.

Huawei noted that Andorra is one of the most fibre-enabled nations in the world, and the leader in European fibre broadband development, becoming the first country to achieve 100% fibre coverage and to eliminate the use of xDSL technology in 2016. The operator announced in February that it had reached full fibre coverage, claiming that it had 38,000 fibre-based customers. Andorra Telecom serves a total of around 45,000 fixed lines, and over 71,000 mobile subscribers.

To meet the growing demand for ultra-broadband services, Andorra Telecom has selected Huawei to deploy a national FTTH network that will enable it to transition from EPON to GPON technology and to provide up to 300 Mbit/s Internet access to its residential and enterprise users in the initial phase.

The project will utilise Huawei's new flagship distributed OLT MA5800, which is designed to support not only GPON Internet access but also allow an evolution to NG-PON (XGS-PON and TWDM-PON) technology, which can deliver bandwidth of up to 10 Gbit/s and help the operator meet bandwidth requirements over the next 10 to 15 years.

Huawei noted the solution for Andorra Telecom will reuse existing ODN (optical distribution network) infrastructure to reduce costs, and for the end user will adopt its advanced ONT and high throughput WiFi router systems.

Fujitsu Labs Unveils Tech for Multi-location Virtual Networks

Fujitsu Laboratories and Fujitsu Laboratories of America have announced the development of technology designed to simplify the delivery and operation of virtual network infrastructures that span multiple clouds and corporate networks.

The company noted that using conventional technology it is possible to build virtual network infrastructure within an individual cloud or corporate location utilising software defined networking (SDN) technology. However, virtual network infrastructure spanning multiple clouds and locations can require a different set-up for each cloud and location and manual configuration to connect each element of the IT infrastructure.

To address this issue, Fujitsu has developed software technology that abstracts the structural elements of networks in the IT infrastructure and which can support design, build, management and operation across multiple IT infrastructures. The company claims the technology can enable virtual network infrastructure to be built in one-tenth the time required with conventional technology for a virtual network infrastructure encompassing one cloud and a location with a few dozen devices.

The now solution developed by Fujitsu Labs and Fujitsu Labs of America functions by abstracting the structural elements of IT infrastructure to enable automated design and deployment of IT infrastructure that extends across multiple locations, while managing and operating the system as a single network infrastructure.

The new technology features elements as follows:

1. IT infrastructure abstraction via modelling of structural elements of IT infrastructure using logical software components to enable key features such as element configuration and operational status monitoring, allowing users to automatically build and operate virtual network infrastructures across multiple instances of IT infrastructure.

2. Virtual network function automatic supplemental technology to support the conversion from a logical to a virtual network infrastructure through deriving the designer's plans from the connection status of the logical network, automatically supplementing network functions by checking the connections between objects at different levels, such as IT infrastructure, subnets and nodes located at each end of a connection.

Fujitsu Labs stated that using the technology it is possible, for example, for a single engineer to design and configure a virtual infrastructure across one cloud and a location with a dozens of devices within one day. In addition, when migrating enterprise systems to the cloud it is possible to rapidly implement a project by performing operations on the logical network, or when setting up a network at multiple locations, by designing one logical network and then implementing a virtual network at each location.

Fujitsu Labs plan to continue development of additional functions for lifecycle management in logical networks using the technology, with the aim that Fujitsu will be able to provide sales as a network management function for enterprise users of cloud services after fiscal 2017.
