Common Management Interface Specification (CMIS) – OIF Common Management Interface Specification (CMIS) The management track in the PLL is currently working on CMIS 5 3, CPO ELSFP, Link training, Form Factor Specific Hardware descriptions as well as forward looking discussions of how to manage modules more efficiently Press Releases
CMIS Common Management Interface Specification This Implementation Agreement (IA) defines the Common Management Interface Specification (CMIS), which may be used by pluggable or on-board modules, such as QSFP Double Density (QSFP-DD), OSFP, COBO, or QSFP, as well as by existing or future module developments with host to module management communication based on a two-wire interface
CMIS: THE KEY TO EFFICIENT MANAGEMENT OF PLUGGABLE MODULES IN NETWORKING To address these ineficiencies and enable new management capabilities, a group of industry experts formed an independent offshoot of the QSFP-DD MSA (Multi-Source Agreement) and developed CMIS This specification was designed to generically manage the wide range of technologies within the pluggable module space Using generic management concepts, CMIS could be reused across different module
CMIS – Versatile Control Set (CMIS-VCS) - oiforum. com CMIS Command Data Block (CDB) An optional feature for command-reply message exchange between host and module It support bulk data transfer (upgrades, performance monitoring, diagnostics and debug, etc)
CMIS Common Management Interface Specification Foreword This CMIS 5 1 specification was developed by the QSFP-DD, OSFP and COBO advisory group Further CMIS revisions with the same major revision number will be backwards specification-compatible to CMIS 5 1 allowing interworking in cases when host and module implement different CMIS revisions1
CMIS Interoperability Demo CMIS-LT GUI cycles through RX equalization presets of the AEC module to select the preset with best BER SNR for each channel When none of the presets are good enough it continues to iterative tuning to find optimal RX equalization that leads to optimal BER per channel Demo Content :
lt;Title gt; C-CMIS – Coherent CMIS – Provides extensions to CMIS to manage modules with coherent interfaces CMIS-FF* – CMIS Form Factor – Provides details of HW pins and related registers for different module form factors CMIS- ELSFP* – CMIS External Laser Small Form Factor Pluggable – Provides details for managing Co-Packaging and ELSFP modules
COMMON MANAGEMENT INTERFACE SPECIFICATION (CMIS) 1 Scope and Purpose This document defines the Common Management Interface Specification (CMIS) as a generic management interface together with a generic management interaction protocol between hosts and modules The CMIS target audience therefore includes suppliers of modules and transceivers, system manufacturers, and system integrators
