Diodes or photodiodes QSFP+ Loopback adapter modules are used

The QSFP+ Loopback also contains a two-colored LED indicator that displays the operating status of the module. Since the QSFP+ Loopback module does not contain laser diodes or photodiodes, it provides a very cost-effective way to test QSFP port  QSFP+ ports during R&D validation, production testing, and field testing. The provides QSFP/QSFP+ power Class (standard), or 4 loading using a customer supplied +3.3V voltage supply.QSFP+ Loopback adapter modules are used for testing QSFP ports on system boards and QSFP switches. The electrical loopback provides a cost effective method for QSFP port testing. Transmitting data from the host is electrically routed (internally to the loopback module) to the receiving data outputs and back to the host.

Genuine Amphenol QSFP+ loopback adapter modules provide the ideal 40-Gigabit rated port testing solution for both QSFP and QSFP+ enabled ports.Buy Compatible QSFP+ Loopback from China factory, ship in 1 day, Return & Refund, Offer Twinax Copper,QSFP/QSFP+ Passive Electrical Loopback EOLQ-XLB is used for testing QSFP/QSFP+ transceiver ports in board level test.
