Oclaro gains access to Ciena’s high-baud-rate DSP to develop 400G coherent transponders

Oclaro Inc of San Jose, CA, USA (which provides components, modules and subsystems for optical communications) has been selected by US-based Ciena Corp as a long-term partner in the development of 400G coherent networks. Oclaro will have access to Ciena’s WaveLogic Ai coherent digital signal processing (DSP) chipset, enabling it to build programmable modules supporting up to 400Gb/s with baud rates that allow more data to be transported on each wavelength. Oclaro says that this will enable customers to quickly and cost-effectively transition to 400G networks capable of meeting the industry's growing demand for more bandwidth.

“Our collaboration with Ciena is a significant milestone in the development of higher-speed 400G networks as it combines world-class 56 Gbaud DSP technology with Oclaro’s indium phosphide transmitter, receiver and modulator technology,” says chief commercial officer Adam Carter. “Oclaro customers will now be able to design high-capacity coherent long-haul/metro systems that are both flexible in the bandwidth offered per port and cost competitive by utilizing a single wavelength,” he adds.

“Oclaro’s deep technology expertise and high-volume success in the 100G market make them a strong partner for driving the evolution to 400G networks,” comments Scott McFeely, senior VP of networking platforms at Ciena. “The combination of our leading baud rate with their proven indium phosphide technology and packaging expertise provides a quick and cost-effective path for early adopters wanting to move to these higher-speed networks,” he adds.

Oclaro expects to sample its first flex coherent transponders based on Ciena’s WaveLogic Ai DSP chipset by the end of 2017. Featuring a single-wavelength transmitter in a 5”x7” form factor, the transponder will be designed to deliver flexible bandwidth for 400G, 300G, 200G and 100G applications.
