CFP 100G Loopback

CFP 100G LoopbackCFP 100G Passive Electrical Loopback is used for testing CFP 100G  transceiver ports in board level test. By substituting for a full-featured CFP transceiver, the electrical loopback provides a cost effective low loss method for CFP 100G port testing. The CFP-100G-loopback is packaged in a standard MSA housing compatible with all CFP ports. Transmit data from the host is electrically routed, (internal to the loopback module), to the receive data outputs and back to the host. It provides an economical way to exercise CFP ports during R&D validation, production testing, and field testing
