Description

The F-tone NetworksFTQ2-HG-LBxx QSFP28 active electrical loopback is used for testing QSFP28 transceiver ports in board level test. By substituting for a full-featured QSFP28 transceiver, the electrical loopback provides a cost effective low loss method for QSFP28 port testing.

The FTQ2-HG-LBxx is packaged in a standard MSA housing compatible with all QSFP28 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 transimpedance amplifier chips, etc., it provides an economical way to exercise QSFP28 ports during R&D validation, production testing and field testing. The FTQ2-HG-LBxx provides QSFP28 power Class 1, 2, 3, or 4 loading using a customer supplied +3.3V voltage supply. Power Classes 5, 6 and 7 are available upon request.
