Broadcom, Cisco, Finisar, Intel, Juniper Networks, Marvell, Molex, and Samtec have combined to create the QSFP-DD800 Multi-Source Agreement (MSA) Group. As the name implies, the MSA plans to create specifications for 800-Gbps module and connector systems leveraging existing work on the QSFP-DD format.

The specification work is expected to target an electrical interface based on eight 100-Gbps lanes. The MSA members also expect to develop a variety of connector specifications, from a standard connector to a stacked connector and a hybrid connector that is a BiPass/Flyover variant that the MSA believes can eliminate the signal losses on a traditional PCB. The QSFP-DD800 will be backward compatible with QSFP-DD, QSFP28, and QSFP+ modules and cables.

“Through continued strategic collaborations with our MSA Promoters, we are developing the physical specifications that will enable the interoperability of optical transceiver modules, connectors, cages, and DAC cables from multiple vendors to assure a robust ecosystem,” said Scott Sommers, founding member and MSA co-chair. “We are thrilled to collaborate together as a group and further develop and provide next-generation designs that evolve with the changing technology landscape.’’

“Leveraging the technical innovations from QSFP-DD, the time is right to collaborate with our MSA partners to lay the foundations for the next generation systems and modules,” added Mark Nowell, founding member and MSA co-chair. “The QSFP-DD form factor continues to be the cornerstone for the next step in pluggable module performance and density, while extending the industry’s investment, experience, cost structure, and backward compatibility from prior generations.”
