OIF launches higher baud rate coherent driver modulator and low-rate service multiplexing white paper projects

News and Business

At this year’s Optical Interworking Forum’s (OIF) 3Q19 Technical and MA&E committees meeting in Montreal, Canada, the organization announced the launch of two new projects; a higher baud rate coherent driver modulator and a white paper detailing low-rate service multiplexing using FlexE and 400ZR.

The Higher Baud Rate Coherent Driver Modulator project will define a new version of the coherent driver modulator supporting at least 96 Gbaud for the low modem implementation penalty segment of the coherent market for single optical carrier line rates beyond 400 Gbps. Designed for higher data rates and longer reach and optimized for performance, this project is the next generation of the High Bandwidth Coherent Driver Modulator (HB-CDM) Implementation Agreement published in 2018.

The second project start is for a white paper on low-rate service multiplexing using FlexE and 400ZR aimed at eliminating ambiguity and providing clarification on how 400ZR should be leveraged in multiplexing applications. Various network operators are looking for a multiplexing scheme to support lower-rate Ethernet clients (e.g. 4x100GE) into a 400ZR coherent line. This technical white paper will educate the market on how FlexE can be used to aggregate low-rate Ethernet services (e.g. 4x100GE) into 400ZR interfaces.

Also, Andrew Schmitt, founder and directing analyst, Cignal AI (pictured), gave member attendees a brief overview of emerging pluggable coherent technologies and the opportunity this new market presents and had the opportunity to speak with members about current and upcoming OIF work.

“It’s clear that OIF is not resting after a successful effort to standardize 400ZR, proven by the launch of two new projects at the recent 3Q meeting,” said Schmitt. “Also, as interest in pluggable coherent solutions grows, it is good to see OIF soliciting feedback from additional network operators in order to shape requirements for next generation standards.”
