A new 100G project has been launched by the Optical Internetworking Forum (OIF) to define a Module Management Interface. The project, started in the Physical and Link Layer Working Group, has set a goal to develop a Management Data Input/Output Interface (MDIO) for the 100G Long Haul DWDM Transmission Module. The MDIO project will specify the logical architecture and frame structure, module control and host-module signaling theory, and MDIO register set. Work on the 100G Long Haul DWDM Transmission Module Multisource Agreement (MSA) began a year ago, and the MDIO interface is an important component to completing the project, enabling multivendor interoperability.
