COBO Components

COBO Components

The Consortium for On-Board Optics (COBO) is a member-driven standards-setting organization, developing specifications for interchangeable and interoperable optical modules that can be mounted onto printed circuit boards.

The organization was founded to develop a set of industry standards to facilitate interchangeable and interoperable optical modules that can be mounted or socketed on a network switch or network controller motherboard.

Modules based on the COBO standard are expected to reduce the size of the front-panel optical interfaces to facilitate higher port density and also to be more power efficient because they can be placed closer to the network switch chips.

COBO's work is important to make the leap to faster networks with the density needed by today's data centers. COBO’s mission is a game-changer for the industry.

MTP/MPO and MXC to MT, Prizm, FA, laser cleaving fiber, and other innovation multi-fiber interconnect interface products, designed to coordinate with optical module chips, will push forward COBO to reach 400G ultra-high speed network application.
