QSFP+ Loopback
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. The loopback module 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. It provides an economical way to exercise QSFP/QSFP+ ports during R&D validation, production testing, and field testing.This loopback module provides QSFP/QSFP+ power Class 2, 3, 4 (standard), or 1,5,6 loading using a customer supplied +3.3V voltage supply.
