The OpenZR+ Multi-Source Agreement (MSA) Group published the OpenZR+ Rev 3.0 specification which defines a higher performing 400G 8QAM mode as well as a higher transmit power mode.
The new specification is designed to further expand the application space for a coherent solution in small form factor pluggable modules, such as form factors defined by the QSFP-DD MSA and OSFP MSA.
“The OpenZR+ MSA is once again paving the way towards multi-vendor interoperability of small form factor pluggables, which are key for enabling network operators to support their growing bandwidth demands in a more cost-efficient manner,” said Atul Srivastava, Co-chair of the OpenZR+ MSA Group.
“With this Rev 3.0 specification, the MSA is continuing to expand the application space for OpenZR+ with new modes designed to address longer reaches and a wider range of network architectures,” said Tom Williams, Co-chair of the OpenZR+ MSA Group.
In the future, the OpenZR+ MSA plans to continue to expand membership in the organization with the goal of further collaborating on improvements to the specification that are in the best interest of the industry. The OpenZR+ MSA expects to play a key role in defining higher data rate operating modes for pluggable coherent interfaces as the industry looks toward 800G and beyond.
