ZTE Carries 400G Single Carrier over 2,125km

ZTE claimed a new record for long-haul 400 Gbit/s single-carrier optical transmission utilising patented compensation algorithms that enable transmission of 84 Gbaud WDM for PDM-8QAM signals over a distance of up to 2,125 km on standard single-mode fibre.

The test is designed to demonstrate the capabilities of ZTE's patented 504 Gbit/s PDM-8QAM technology for 400 Gbit/s transport. The test involved 84 GBaud PDM-8QAM signals generated and pre-processed by a 84 GSa/s digital analogue converter with joint pre-equalisation and look-up-table pre-distortion algorithms. Using receiver-side digital-backward propagation (DBP) fibre nonlinearity compensation, ZTE achieved eight-channel WDM transmission with EDFA-only amplification enabled.

ZTE noted that in 2015 it partnered with OFS to deliver transmission of 128.8 Gbaud WDM QPSK signals over 10,130 km and 6,078 km of terrestrial fibre at different spectrum efficiency, while in 2016 it demonstrated single-carrier 800 Gbit/s transmission with 120 Gbaud WDM 16QAM signals over 1,200 km terrestrial fibre links.

Inphi unveils 64 Gbaud linear TIA/VGA amplifier

Inphi announced production availability of its IN6450TA 64 Gbaud dual channel linear TIA/VGA amplifier, and that its 32 Gbit/s quad linear TIA with analogue and digital SPI interfaces and second-generation single chip quad channel linear driver in bare die form will be combined as a chipset to address the requirements of 100/200 Gbit/s coherent systems for metro and long haul applications.

64 Gbaud linear TIA/VGA amplifier

Inphi has announced production availability of its IN6450TA device, claimed as the first 64 Gbaud dual channel linear TIA/VGA amplifier, offering support for data rates of 400 to 600 Gbit/s per wavelength and targeting long haul, metro and data centre interconnect (DCI) applications.

The company noted that with growing demand for bandwidth, service providers and data centre operators require more efficient technologies, such as flexible coherent DWDM transmission capable of changing transmission capacity and reach on demand. This capability is enabled through the use of components capable of supporting multiple modulation formats and baud rates; the IN6450TA is designed to work with modulation formats supporting data rates of up to 600 Gbit/s on a single wavelength.

Inphi stated that it worked with NeoPhotonics on the design of the IN6450TA and its incorporation into NeoPhotonics' 64 Gbaud micro-ICR targeting applications in high-density line cards and pluggable transceivers.

Chipset for 100/200 Gbit/s coherent systems

The IN3254TA and IN3226DZ devices are designed to be integrated to enable higher density, lower cost solutions for emerging coherent optical sub-assembly (COSA) components. COSA implementations are designed to enable delivery of the newly proposed CFP2-DCO form factor, as well as provide the more compact, lower cost ACO modules with higher port-count line cards for 100/200 Gbit/s coherent transmission applications.

Inphi noted that for 100 Gbit/s, a major part of the growth is attributed to the CFP2 coherent modules expanding the addressable market for pluggable transceivers. The company's new transceivers are intended to enable the next generation of 100 and 200 Gbit/s networking infrastructure for metro and inter-data centre markets, where smaller size, lower cost and pluggable modules are the key requirements.

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".

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.

Fujitsu Intros Access-agnostic Virtual Access Network for SMBs

Fujitsu Network Communications has introduced its Virtual Access Network (VAN) solution, designed to address the cost and time barriers for small-to-medium business (SMB) service deployment by eliminating the need for purpose-built routing devices and manual provisioning and allowing the use of any access technology to deliver services, and will showcase the solution at OFC 2017.

Fujitsu noted that SD-WAN and access services can be cost-prohibitive for SMB customers, thereby resulting in an underserved market. Fujitsu's new VAN solution is designed to enable delivery of SMB services more cost-effectively by removing the need for operators to deploy CPE routing devices requiring manual, on site provisioning. VAN also provides a single solution that can be used to deliver virtualised products using multiple access technologies.

The VAN solution helps to minimise service delivery time and costs leveraging features including centralised compute resources. By virtualising and centralising network functions, the solution both improves performance and makes services easier to manage.

Fujitsu's VAN solution comprises a services gateway unit, a low-cost whitebox that can support services over any access medium, a plan and provision tool that allows zero-touch plug-and-play provisioning, and a virtual private service VNF that serves to replace traditional routers.

The complete solution is designed to help operators: deploy new services without the need for manual provisioning; deliver seamless access regardless of underlying technology, whether fibre, copper, HFC, WiFi or LTE; reduce the cost of service delivery; and enable the delivery of competitively priced services to end customers.

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".

AT&T Conducts 400G Field Trial

AT&T completed the first of a multi-phase trial testing 400 gigabit Ethernet data speeds. This first phase used optical gear from Coriant to carry a true 400GbE service across a long-distance span of AT&T global backbone from New York to Washington, demonstrating that AT&T’s nationwide software-centric network is 400G-ready.

A second phase of the trial will carry a 400GbE on a single 400G wavelength across AT&T’s OpenROADM metro network. This phase is expected to use optical gear from Ciena.

 A third phase is expected to test the first instance of a 400GbE open router platform. The “disaggregated router” platform uses merchant silicon and open source software – and this is expected to be another industry first.

“Our approach to roll out the next generation of Ethernet speeds is working. We continue to see enormous data growth on our network, fueled by video. And this will help with that growth,” said Rick Hubbard, senior vice president, AT&T Network Product Management.

In a post deadline paper at OFC, researchers at AT&T Labs described the trial, which encompassed an end-to-end 400G Ethernet circuit, inclusive of 400GbE client cards with a CPF8 interface and dual-carrier 16QAM line-side. The trial demonstrated the feasibility of SDN-enabled creation, deletion, and re-routing of the 400G service.

Ciena Opens WaveLogic to Lumentum, NeoPhotonics and Oclaro

Ciena announced it is extending the market reach of its WaveLogic coherent modem technology by making it available to a number of industry participants, with optical component companies Lumentum, NeoPhotonics and Oclaro to leverage WaveLogic technology to develop coherent optical modules for a range of applications.

Additionally, each of the companies will join an ecosystem that will focus on standards-based product development, designed to provide customer choice in the emerging 400 Gbit/s pluggable market, which is being driven by increasing data centre interconnect (DCI) requirements.

Ciena stated that while retaining its intellectual property rights, through the initiative it will provide its WaveLogic Ai chipset to Lumentum, NeoPhotonics and Oclaro. The partners will each be responsible for the manufacture, sale and distribution of Ciena-designed 5 x 7 coherent modules based on a combination of the WaveLogic technology and electro-optics components.

In addition, under the agreement the partner companies will contribute to the ongoing development of 400 Gbit/s pluggable technologies and the establishing of specifications for adoption by relevant industry forums and standards-setting bodies. Ciena intends to invest in further developing coherent DSP technology, which its partners will then be able to utilise in the development of 400 Gbit/s pluggable modem solutions for hardware and systems vendors.

Lumentum, NeoPhotonics and Oclaro will also support the creation of a roadmap for future generations of coherent optical modules based on Ciena's WaveLogic technology.

Separately, Oclaro announced it has been selected by Ciena as a partner for the development of 400 Gbit/s coherent networks leveraging Ciena's 56 Gbaud WaveLogic Ai coherent DSP chipset. The technology will be used to develop programmable modules supporting up to 400 Gbit/s rates.

Oclaro stated that it expects to sample its first 400 Gbit/s flex coherent transponders based on the WaveLogic Ai DSP chipset by the end of the year. The device will feature a single wavelength transmitter in a 5 x 7 inch form factor designed to support flexible bandwidth for 400, 300, 200 and 100 Gbit/s applications.

Coriant Unveils Aware Toolkit for Real-time Optical Performance, Control Capability

Coriant has announced the introduction of Coriant Aware Technology, an new software-enabled toolkit designed to enhance the value of dynamic optical networks via sophisticated real-time performance awareness and control functionality.

In a live demonstration at OFC 2017, Coriant will showcase how the Aware technology can be used to enable faster and simpler new wavelength planning and provisioning, increased reach and capacity and improved service availability.

Coriant noted that existing networks suffer from limitations that can increase costs, increase wavelength activation times, limit reach and reduce efficiency, with these limitations in part due to planning tools that do not have real-time data from the optical network, as well as coherent receivers that are unable to measure OSNR and NMS, SDN and ASON/GMPLS implementations that lack the optical models of offline planning tools. In addition, the adoption of SDN and flexi-rate interfaces will further emphasise these limitations.

The new Coriant Aware technology is designed to correlate, analyse and act upon real-time data by applying concepts already used for the Internet of Things (IoT) and help to address these limitations, as well as help operators reduce capex and opex.

Coriant noted that residual margin in a network is affected both by OSNR and linear and non-linear impairments, so that accurately assessing residual margin means determining the impact of all three factors. For example, while current coherent receivers may be able to measure linear effects such as CD, PMD and PDL, they cannot measure the impact on signal quality, nor accurately measure OSNR or the effect of nonlinear penalties.

To address these issues, Aware technology features two components: the Optical Performance Engine (OPE) and Margin Processing Engine (MPE).

Optical Performance Engine

OPE is designed to combine the accuracy of an offline planning tool with the real-time speed needed for wavelength activation, Layer 0 restoration, and other optical use cases, with real-time performance enabled by simplifying the mathematical operations.

The OPE responds to path validation requests from the path computation function within the NMS, SDN or ASON/GMPLS control plane. With optical models that incorporate both linear and nonlinear effects, the OPE generates valid options for each requested path, including modulation types, baud rates, FECs, frequencies and power levels to allow the optimum options, including flexi-rate interface settings and super-channels, to be selected.

Margin Processing Engine

MPE is designed to enable operators to accurately estimate residual margin by collecting performance monitoring data from across the network, including coherent receivers and per-channel power monitoring capabilities of the network elements. It then processes this data in real-time to distinguish OSNR from signal degradation due to linear and nonlinear impairments, providing accurate, real-time residual margin values for each channel.

Additionally, MPE is able to provide this without the need for next-generation DSPs, allowing use with installed coherent interfaces.

Key capabilities enabled by Coriant Aware technology include:

1. Increased transmission reach and capacity by reducing or eliminating margin stacking and optimising power levels.

2. Faster wavelength service activation through reducing the provisioning steps required and the boundaries between planning and management systems.

3. Higher availability via support for SDN or ASON/GMPLS restoration, enabling a reduction in margin requirements for temporary restoration paths and pro-active downtime prevention.

4. Allows operators to use margin as extra capacity that can be provided to customers.

Coriant Aware technology will be introduced in phases, with initial OPE functionality due to be available for trials beginning in the second quarter of 2017.

Oclaro Unveils I-Temp Transceivers for 5G fronthaul, Samples 400G

Oclaro announced the introduction of two new industrial temperature (I-temp) transceivers designed to drive the market transition to 5G wireless fronthaul systems and sampling of its 400 Gbit/s CFP8 transceiver for core routers/transport applications.

I-temp transceivers

Oclaro's new I-temp transceivers are designed to provide customers with the flexibility to choose either a 10 Gbit/s TSFP+ I-temp that can fit a WDM fronthaul system into a next generation 5G wireless network, or a 25 Gbit/s SFP28 LR I-temp that significantly increases data capacity and offers industry-leading low power consumption.

The TSFP+ is Oclaro's latest product to include I-temp and follows the company's 10 Gbit/s TSFP+ C-temp and E-temp devices, which are already shipping. The TSFP+ is vertically integrated based on Oclaro's in-house ILMZ chip and custom-designed TOSA and TSFP+ technology. Oclaro has enabled 85 degrees C operation by optimising the operation temperature of the ILMZ chip and -40 degrees C operation by developing TEC to lower power consumption, as well as improving power dissipation of key components.

Oclaro expects to begin sampling the 10 Gbit/s TSFP+ I-temp in April, with volume production due to start in the third quarter of 2017.

400 Gbit/s CFP8 transceiver

Oclaro's 400 Gbit/s CFP8 transceiver targets core routers/transport applications and leverages its EML laser and receiver technology to deliver higher data rates between high-end routers and optical transport systems. At OFC Oclaro will demonstrate the CFP8 operating with 8 lasers at 50 Gbit/s PAM4.

With a 40 x 102 x 9.5 mm form factor, the 400 Gbit/s CFP8 transceiver provides a high density, high-throughput solution. The CFP8 leverages technology from Oclaro's earlier CFP, CFP2 and CFP4 designs, including its cooled 1310 nm 28 Gbit/s EA-DFB lasers, integrated TOSA and ROSA and 28 Gbit/s 4 channel integrated PIN-PD array.

The CFP8 transceiver for reach of 2 km and 10 km is compliant with 400GBASE-LR8 optical and 400GAUI-16 electrical interface specifications, offers EML laser technology offering good margin over IEEE 400 Gigabit Ethernet optical specifications and receiver bandwidth capability to allow interfacing with different lasers.

Oclaro's CFP8 product is currently sampling, with volume production scheduled for the second half of 2017.
