The StarTech.com LOOPBACKMTP12OS2SMF is a single mode MPO loopback module for checking signal continuity, insertion loss and port function on MPO-based fibre links. Its non-pinned (female) MPO-12 connector works with 9/125 µm OS1 and OS2 cabling.

Precision-aligned ferrules in a fixed 12-fibre configuration keep insertion loss below 0.35 dB with return loss above 50 dB, so results stay consistent from test to test. The compact ABS body is rated for 1,000 test cycles and comes with a dust cap.
