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.
