25G SFP28 Electrical Passive Loopback

Product Description
The F-tone Networks SFP28 passive electrical loopback is used for testing SFP28 transceiver ports in board level test. The electrical loopback provides a cost-effective low loss method for SFP28 port testing.
The FT-33-ZSP-LBX is packaged in a standard MSA housing compatible with all SFP28 ports. Transmit data from the host is electrically routed (internal to the loopback module) to the receive data outputs and back to the host. Since the loopback module does not contain laser diodes, photodiodes, laser driver or trans impedance amplifier chips, etc., it provides an economical way to exercise SFP28 ports during R&D validation, production testing and field testing.
