24 Fibers MMC Female Type 1 Fiber24 Fibers MMC Female Type 1 Fiber Loopback Module, OM4
Singapore high-density designs should assess this item together with panel access, cable routing and the complete optical loss allowance. This 24-fiber OM4 loopback terminates in an MMC female APC connector and uses Type 1 fiber map to return transmitted lanes to the receiver. It supports multimode port diagnostics and burn-in without a second active device. The short 250mm product incorporates a 100mm fiber loop, G.657.A2 glass and a 2.5mm plenum jacket.

OM4 and 24-fiber mapping in one test module
Both fiber mode and fiber count must correspond to the active hardware test plan. Type 1 map defines the return channels; concurrently, the female APC MMC interface must connect to the proper pinned APC mate. Keep this test assembly distinct from OS2 and 16-fiber versions so a visually analogous connector will not by itself lead to an invalid test arrangement.
Interpreting results with passive loop loss
Maximum insertion loss is 0.7dB and minimum return loss is 40dB. The loop’s attenuation is part of the optical channel seen by the receiver and should be considered before plan conclusions about a marginal port. Use the loopback assembly for controlled port checks, then make sure of the installed optical path separately with its actual passive components.
Storage and repeated test cycles
The loopback assembly is specified for 50 mating cycles. Its loop and total length have defined mechanical tolerances, but those dimensions do not attempt to permit sharp bending or pulling by this optical cable. Clean the ferrule before use, respect the 7.5mm optical-fiber bend minimum and fit the dust cap immediately after the test.
Ordering and Factory Support
Reference LPM-OM4-24MMC during the request for the 24-fiber OM4 Type 1 loopback. State quantity and any asset-label needs; for procedures requiring Type 2 or another fiber mode, ask for the custom map instead of substituting the specified model. Singapore and regional project orders can be reviewed for interface compatibility, packing details and delivery coordination.
