MPO Loopback
MPO loopback module for troubleshooting fiber networks
MPO loopback modules are widely used in test environments, especially in parallel optical 100G networks. The device allows verification and testing of optical modules with MPO interfaces – 100GBASE-SR10 CXP/CFP modules. The MPO loopback module is widely used to connect the transmitter (TX) and receiver (RX) ports of the MPO optical module interface. It can facilitate and accelerate IL testing of optical network segments by connecting them to MPO trunk/jumper leads. OMC has been providing MPO loopback module since 2007, it’s popular among our clients due to its high quality and performance. Below is a detailed introduction about the loopback to help you understand it better.
What is MPO Loopback?
MPO loopback is a passive optical device including an MPO loopback patch cable, which can pass both ends of the optical fiber into an MPO connector to achieve the optical path in the same connector, with no need to change the signal or repeat the signal back to itself. Usually, there is a black cover on the outside for protection.
MPO loopbacks can be classified from the following aspects
The Features of OMC MPO Loopback

Flexible Fiber Options: Available in G657A SM MPO loopback, OM3 MPO loopback, OM4 MPO loopback module, our MPO Loopback can simulate internal network distances, providing versatility for different network configurations.
What’s the function of MPO loopback
MPO loopback is mainly used for fiber loopback testing, where signals are sent from a communication device and returned to the device to check whether the device is working well. They are often used to check whether a fiber optic transceiver is functioning properly as designed. There are two ports for transeiver, one is sending signals and another one is receiving signals. MPO loopback provide a quick and efficient way to test the transmission capability and receiving sensitivity of optical network equipment and locate various potential anomalies. MPO loopbacks with different core counts have different polarity channel alignment configurations. For example, an 8cores MPO loopback is usually aligned at both ends of the connector, leaving the 4 channels in the middle empty. MPO loopbacks are suitable for 40/100G network communications, and can locate various potential phenomena through return signals, thereby achieving effective testing and evaluation of individual components or interfaces and networks on paired optical networks.
