OIF Webinar hosted by Lightwave

This event was broadcast on October 4, 2022.

With widespread deployments and continuous feature additions, the Common Management Interface Specification (CMIS) is the leading management interface for modules ranging from copper cables to coherent pluggables.

Understanding the features and implications of the current generation of CMIS and future planned additions is critical whether you provide host silicon, module silicon, optics, copper cables, and if you design and build equipment or are a network operator. CMIS is a powerful, far-reaching tool set you will need to be aware of for its impact on current and future generation designs.

Watch this free, OIF-sponsored workshop to hear from module vendors, systems vendors, and network operators on what CMIS is and why it is important to the entire industry.
