8/12/24-Fibers MPO Fiber Loopback Module
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.
8F MPO Fiber Loopback Module allows verification and testing of transceivers featuring MPO interface – 40GBASE-SR4/CSR4 QSFP+ devices.
12F MPO Fiber Loopback Module allows verification and testing of transceivers featuring MPO interface – 40GBASE-SR4 QSFP+ or 100GBASE-SR4 devices.
24F MPO Fiber Loopback Module allows verification and testing of transceivers featuring MPO interface – 100GBASE-SR10 CXP/CFP devices.
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.

12-MPO VS 24-MPO
12-fiber MPO interface for 40 Gig means 4 lanes at 10 Gig per lane over singlemode or multi-mode fiber for a total of 8 fibers (i.e.,4 transmit and 4 receive).
24-fiber MPO interface for 100 Gig means 10 lanes at 10 Gig per lane over singlemode or multi-mode fiber for a total of 20 fibers (i.e.,10 transmit and 10 receive).
Application in Data Center
Collocated with 40G or 100G MPO/MPO interface transceivers
Loopback Module can be used for testing the transmission capability and receiver sensitivity of fiber optic network equipment.
