The OIF stated that it has adopted the responsibility of the Common Management Interface Specification (CMIS) developed by the Multi-Source Agreement (MSA) Quad Small Form Factor Pluggable Double Density (QSFP-DD). This decision follows the announcement last August that the OIF would create a physical and link layer (PLL) working group management track that would adapt to this development (see “The OIF launches the CEI project -112G-Extra Short Reach (XSR) + ”).
In addition to revealing the creation of the PLL working group management track, the OIF also revealed the launch of a project that would create CMIS extensions for co-packaging implementations. Future CMIS revisions, enhancements and expansions will occur within this track, which is co-chaired by Gary Nicholl of Cisco and Ian Alderdice of Ciena.
In addition to QSFP-DD optical modules, CMIS can be applied to OSFP, COBO and QSFP optical transceivers as well as future module developments for applications such as co-packaged optics with host-module based management communication. on two wired interface. CMIS-compliant system manufacturers, system integrators, and optical and copper module suppliers will likely follow this work closely.
“The QSFP-DD MSA initiated the CMIS effort to meet an industry need for common plug-in module management, and it has been widely and successfully adopted in the industry,” said Mark Nowell of Cisco, founding member of the QSFP-DD MSA and MSA group. co-chairman. “The OIF is very well placed to maintain and expand the development of this effort and I look forward to seeing their progress. “
“The adoption of CMIS from the MSA QSFP-DD, with the aim of developing and extending the specification, is an ideal extension of the work of the OIF,” said Nathan Tracy of TE Connectivity, vice president of the OIF. marketing of OIF and TE Connectivity. “The OIF is where the cloud does its work, and the extension of CMIS is a giant leap and an integral link with the other work that OIF members are doing to enable an interoperable ecosystem. “
The current CMIS and previous revisions (of QSFP-DD MSA) are now available to members on the OIF website. The “Archived non-OIF generated specifications” can be found on the home page, in the “Documents” drop-down menu.
