12 Fibers MTP Fiber Optic Patch Cables Multimode Fiber MPO Loopback Cable
12 Fibers MTP/MPO Female Type 1 50/125 Multi-Mode Fiber Loopback Cable MPO Patch Cord
MPO Loopback cable provides a looped signal to test the transmit and receiving functions. It used widely within testing environment especially within parallel optics 40 and 100G networks.
Loopbacks are built to link Transceivers (TX) and Receivers (RX) positions of MPO transceivers interfaces. MPO loopbacks can facilitate and speed up IL testing of optical networks segments by connecting them to MPO trunks/patch leads.
MPO loopback assemblies’ standard products include a female MPO 12-fiber interface with 8-fiber Quad SmallForm-actor Pluggable (QSFP) option or 24-fiber, singlemode or multimode ferrules. Our compact and rugged
housing design provides high stability and reliability.
12F MPO Fiber Loopback Cable allows verification and testing of transceivers featuring MPO interface – 40GBASE-SR4 QSFP+ or 100GBASE-SR4 devices.
OMC offers a line of MPO fiber optic loopback assemblies for burn-in and testing of MPO network components and systems. These MPO Loopback Assemblies are used to effectively test transmitter capability and receiver sensitivity of network equipment, particularly for telecom and datacom requirements. They are packaged in a compact housing for the highest density available for these applications.
