The Open Compute Project (OCP) has accepted specifications for the Wedge 100, Facebook’s second-generation top-of-rack (ToR) switch for its 100G data centers. Facebook has marked the occasion by providing details of the switch in a blog post so that others might deploy it as well. The company says it also will work with the University of New Hampshire’s Interoperability Lab to enable optical transceiver vendors to qualify their optical modules for use in the system.
