OIF released the latest Common Management Interface Specification (CMIS) Implementation Agreement (IA) version 5.3, alongside two new specifications and a white paper aimed at improving CMIS interoperability across the industry. The updates include the External Laser Small Form Factor (ELSFP) Pluggable CMIS IA, the Formfactor Specific Hardware Management (CMIS-FF) IA, and the white paper titled “CMIS: Path to Plug and Play.” These developments aim to simplify the integration of high-speed networks, reduce deployment time, and enhance module functionality.
The OIF’s Common Management Interface Specification (CMIS) Implementation Agreement (IA) is a technical standard for the management and control of modules in optical networks, including monitoring and control of power consumption, temperature, optical/electrical signal quality, and fault detection and diagnostics.
The new CMIS 5.3 IA introduces several new features, including support for Co-Packaged Optics, ELSFP, and serial peripheral interface (SPI), as well as new advertising capabilities that allow modules to communicate per-application power consumption and custom media/host codes. The update applies to various module types such as QSFP-DD, OSFP, and COBO, enabling system manufacturers, integrators, and module suppliers to ensure seamless management communication between host systems and modules through a two-wire interface.
Additionally, the ELSFP Pluggable CMIS IA and CMIS-FF IA enhance the management of external laser small form factor modules and define hardware signal usage for form factors that differ from CMIS-managed modules. The newly released white paper highlights the “Path to Plug and Play”, explaining how CMIS 5.3 enhancements can accelerate network deployments by reducing integration times and enabling standard provisioning models.
• OIF released CMIS 5.3 IA, along with ELSFP Pluggable CMIS IA and CMIS-FF IA.
• CMIS 5.3 includes new functionalities like Co-Packaged Optics and SPI, plus module capability advertising.
• ELSFP Pluggable IA aligns external laser modules with CMIS, while CMIS-FF IA provides hardware signal management.
• The white paper outlines how CMIS advancements pave the way for plug-and-play functionality in high-speed networks.
“These industry-critical IAs represent significant strides in advancing CMIS interoperability across the industry,” said Gary Nicholl, OIF Board Member and Physical and Link Layer (PLL) Working Group – Management Co-Vice Chair, and Cisco. “These new standards not only enhance the functionality of modules but also streamline the integration process, reducing the time to market for new technologies.”
