MPO Loopback Assemblies are designed for testing of MPO parallel links and for device burn-in. By creating a loop of signal from transmitter to receiver within one MPO plug it forms optical link which allows testing of optical network segment by segment. Our MPO loopback cables are factory pre-terminated, tested and packed along with the test reports. 12 Fiber MPO loopback patch cord assemblies are used to loopback CFP/CFP+/CXP transceivers.
