Since the loopback module does not contain laser diodes, photodiodes, laser driver or trans impedance amplifier chips, etc., it provides an economical way to exercise the ports during R&D validation, production testing and field testing. Transmit data from the host is electrically routed (internal to the loopback module) to the receive data outputs and back to the host.

They are backed by a lifetime warranty, and you can buy with confidence. All our fiber transceivers, active optical cable and direct attach cables are 100 compatible with major brands like Cisco, HP, Juniper, Finisar, Nortel, Force10, D-link, 3Com. It is also sometimes referred to as RJ45. A loopback cable is also known as loopback plug or loopback adapter, which is a plug used to test physical ports to identify network issue. Fibermart also provide Active Optical Cable AOC for 100G QSFP28, 40G QSFP+, 25G SFP28, 400G QSFP-DD. These loopbacks are packaged in a standard MSA housing compatible with all SFP+/SFP28/QSFP+/QSFP28 ports. An Ethernet loopback plug is a tool that can help troubleshoot problems with network connection or to test the Ethernet cables and networking hardware. The electrical loopback provides a cost effective low loss method for port testing. The 10Gtek passive electrical loopbacks are used for testing transceiver ports in board level test. 10Gtek provides extensive loopbacks on SFP+, SFP28, QSFP+, QSFP28 and QSFP-DD. They are hot pluggable, constructed of metal cast for excellent EMI performance. Juniper QFX5110, 48 SFP+ and 4 QSFP28, Back to Front AC. The electrical passive loopbacks from 10Gtek intend to support Datacom, Infiniband, Fiber Channel applications, which provides a method for port operations testing in board and system. Juniper QFX5110, 48 SFP+ and 4 QSFP28, Back to Front AC TINVEST.
