MTP® Loopback Assemblies are designed for testing of MTP® parallel links and for device burn-in. By creating a loop of signal from transmitter to receiver within one MTP® plug it forms optical link which allows testing of optical network segment by segment. Our MTP® loopback cables are factory pre-terminated, tested and packed along with the test reports. 12 Fiber MTP® loopback patch cord assemblies are used to loopback QSFP+/QSFP/PSM4 transceivers
