The MPO loop contains the MPO back ring jumping line in the LOOPBACK, and puts both ends of the

fiber into an MPO connector to achieve the light path in the same connector. The launch capacity and

receiving sensitivity of the device, especially in 40/100G network communication, can locate various

potential phenomena by returning signals to achieve effective testing and evaluation of a single component

or interface on the fiber network.

There are many configurations of optical fiber circuit, which can accommodate 8 -core, 12 -core and 24 -

core MPO connector and several fiber fiber configurations to adapt to the port in the test.8F MPO Fiber

Loopback Module allows verification and testing of transceivers featuring MPO interface – 40GBASESR4/

CSR4 QSFP+ devices. 12F MPO Fiber Loopback Module allows verification and testing of

transceivers featuring MPO interface – 40GBASESR4 QSFP+ or 100GBASE-SR4 devices. 24F MPO

Fiber Loopback Module allows verification and testing of transceivers featuring MPO interface –

100GBASESR10 CXP/CFP devices.

MPO Loopback modules 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.

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.
