QSFP28 Loopback
QSFP28 Loopback
QSFP28 Electrical Passive Loopback has Excellent signal integrity, It is used for Economical and flexible 100Gbps QSFP28 port testingBoard level system testing and Power on validation.The loopback module is packaged in a standard MSA housing compatible with all QSFP+/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. It provides an economical way to exercise QSFP/QSFP+ ports during R&D validation, production testing, and field testing.
