QSFP+ Loopback

Model#: QSFP-LB-xx
QSFP+ Loopback
QSFP/QSFP+ Passive Electrical Loopback is used for testing QSFP/QSFP+ transceiver po s in board level test. The electrical loopback provides a cost effective low loss method for QSFP/QSFP+ po testing. The loopback is packaged in a standard MSA housing compatible with all QSFP/QSFP+ po s. 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+ po s during R&D validation, production testing, and field testing. The loopback provides QSFP/QSFP+ power Class 1, 2, 3 (standard), or 4 loading using a customer supplied +3.3V voltage supply.
