The Gigalight 100G QSFP28 loopback active electrical module (GQS-MPO101-LP) is designed for testing QSFP28 ports in board-level test by substituting for a full-featured QSFP28 transceiver, providing data center customers with a cost-effective solution for QSFP28 port testing.Get a Quote
The 100G QSFP28 loopback is packaged in a standard QSFP MSA housing that is 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, photo-diodes, laser driver or trans-impedance amplifier chips, etc., it provides an economical way to exercise QSFP28 ports during R&D validation, production testing and field testing. The loopback module 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.
