12-Fiber Single Mode MPO fiber loopback tester for fiber optic testing or network restorations. 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. Single Mode OS2 MPO Female Loopback Module, 12-Fiber. MPO Loopback Connector is designed for testing of MPO parallel links and for device burn-in. Our compact and rugged housing design provides high stability, reliability, and repeatability. MPO loopbacks standard products include a female MPO interface 12-fiber with 8-fiber (QSFP) option or 100G, singlemode or multimode versions. MTP/APC Singlemode loopbacks, and MTP/UPC Multimode loopbacks using high quality US Conec MTP connectors for the highest quality polish and lowest insertion loss. The MPO fiber cables are packaged in a rugged, compact housing for the highest density available for these applications. Fibertronics offers single mode and multimode MTP MPO fiber optic loopbacks. Containing the fiber loop inside, MPO loopback can realize the optical path in the same one connector, and transmit the optical signal from the transmitter. MPO fiber connectors utilize precision molded MT ferrules, with metal guide pins and precise housing dimensions to ensure fiber alignment when mating.

The MPO fiber cable connector offers up to 12 times the density of standard connectors, providing significant space and cost savings. The singlemode or multimode MPO connector are multifiber connections used in high-density backplane and Printed Circuit Board (PCB) applications in data and telecommunications systems.
