Product Information

The QSFP28 passive electrical loopback module is used for testing QSFP28 transceiver ports in board level tests. By substituting for a fully-featured QSFP28 transceiver, the electrical loopback provides a cost effective, low loss method for QSFP28 port testing. The module is packaged in a standard MSA housing that is compatible with all QSFP28 ports.

Transmitted data from the host is electrically routed withing the loopback module to the receiving data outputs and back to the host. Since the loopback module does not contain the additional components found in a transceiver (laser diodes, transimpedance amplifier chips, etc.), it provides a cost effective way to test QSFP28 ports during R&D validation, production testing, and field testing.
