Loopback SCA Singlemode Module 3mm

SCA/APC Duplex 9/125 Singlemode fibre Loopback module 3mm.

Fibre Optic Loopback modules are designed to assist in testing and network diagnostics.

A loopback test eliminates redundant connections and confirms that a transceiver or port is functioning properly.

The test is performed by using the transmit and receive in the same module.

A self-contained loopback module or a single strand of fiber is required to complete this test.
