News and Business

As part of its goal to drive multi-vendor interoperability of enhanced performance coherent pluggable modules, the OpenZR+ Multi-Source Agreement (MSA) Group today announced that it has published the OpenZR+ Rev 1.0 specification and a supporting whitepaper. This specification, based on high-gain oFEC, is designed to enable 100G to 400G line rates, multiplexing and extended reaches in high-density form factors, such as QSFP-DD and OSFP.

Going forward, the MSA plans to continue to expand membership in the organisation and collaborate on improvements to the specification. Recent MSA discussions have focused on tighter 75 GHz channel spacing, which increases the total transmission capacity of the DWDM line system, but can introduce penalties due to additional filtering and crosstalk. The enhanced oFEC performance of OpenZR+ can help network operators address these 75 GHz applications.

“By delivering high-performance and interoperability, OpenZR+ addresses not only regional and long-haul interconnects in hyperscale data centre applications, but also supports service provider requirements,” said Atul Srivastava, Co-chair of the OpenZR+ MSA Group.

“OpenZR+ enables network operators to address 400G regional interconnects beyond 1,000 km, and even long-haul requirements with 200G reaches beyond 2,500 km, using interoperable modules from multiple vendors,” said Tom Williams, Co-chair of the OpenZR+ MSA Group.

Current members of the mSA Group include Acacia Communications, Arista Networks, Cisco, Fujitsu Optical Components, InnoLight Technology, Juniper Networks, Lumentum, and NTT Electronics.
