Also known as loopback plug and fiber optic loopback cable, loopback adapter is a device which feeds the received signal back to the sender. By sending back the signal, it is used to detect the potential problems in network links. A link between two points in different locations may be tested by applying a test signal on the link in one location, and having the loopback at the other location send a signal back through the link. If this fiber optic loopback adapter receives its own signal back, this proves that the link is properly functioning.
We provide different kinds of fiber optic loopback connectors. The connector used come in different types such as SC, LC, MU, MT-RJ. The loopback adapter comes with bare fiber or 0.9mm cable and 2.0mm cable. It can be customized according to customers' specific requirements. It is compliant with ROHS standard.
