OpenZR+ MSA Group Formed to Expand DCI Interoperability in Pluggable Module Form Factors
MAYNARD, Mass. and YOKOHAMA, Japan, May 21, 2020 (GLOBE NEWSWIRE) -- Seven optical communications vendors of components, modules and systems today announced that they have formed the OpenZR+ Multi-Source Agreement (MSA) Group to define an open, flexible and interoperable coherent DWDM solution in a small form factor pluggable module. The OpenZR+ implementation is designed to enable enhanced functionality and improved performance in pluggable form factors, such as QSFP-DD and OSFP. Network operators can utilize OpenZR+ modes to support 100 to 400 Gb/s data rates and efficient multiplexing of Ethernet clients with extended reaches to address high-density regional and long haul applications.
Initial members include Acacia Communications, Cisco, Fujitsu Optical Components, InnoLight Technology, Juniper Networks, Lumentum, and NTT Electronics.
The goal of the OpenZR+ MSA is to specify the interoperation of modules utilizing the Ethernet-optimized ZR framing with the higher gain oFEC to enable a range of enhanced performance modes operating at 100 Gb/s, 200 Gb/s, 300 Gb/s and 400 Gb/s rates in support of single or multiplexed Ethernet interfaces.
“The OpenZR+ members are working together to develop the protocol and optical specifications to support an expansion of the use cases for interoperable coherent pluggable modules in a QSFP-DD or OSFP form factor,” said Atul Srivistava, Co-chai of the OpenZR+ MSA Group.
“By ensuring multi-vendor support for OpenZR+, the objective of this MSA is to enable network operators to expand the application space for the 400ZR operational model without sacrificing interoperability,” said Tom Williams, Co-chair of the OpenZR+ MSA Group.
MSA Members Acacia Communications and NTT Electronics have already announced that they have completed testing to demonstrate interoperability between OpenZR+ coherent DSPs by exchanging test vectors. The MSA plans to publish a specification defining operating modes that will allow other DSP vendors to develop solutions that interoperate with OpenZR+.
