QSFP+/QSFP28
QSFP+Loopback
QSFP/QSFP+ passive electrical loopback is used for testing QSFP/QSFP+ transceiver ports in board level test. By substituting for a full-featured QSFP/QSFP+ transceiver, the electrical loopback provides a cost effective low loss method for QSFP/QSFP+ port testing. Attenuation options are available in nominal and attenuated versions including 0db, 3.5db and 5db; power options are 1W, 2W, 3.5W; plug in and out can reach to 500times.
QSFP/QSFP+ is packaged in a standard MSA housing compatible with all QSFP/QSFP+ 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 QSFP/QSFP+ ports during R&D validation, production testing, and field testing. The QSFP+ loopback provides power Class 1, 2, 3 or 4 loading using a customer supplied +3.3V voltage supply.
