For UAE project teams, the key is to match this exact configuration to the port schedule, optical budget and delivery documentation. 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 unit incorporates a 100mm fiber loop, G.657.A2 glass and a 2.5mm plenum jacket.

Specifications

OM4 and 24-fiber mapping in one test module

The two fiber mode and fiber count must be matched to the active equipment test plan. While the female APC MMC interface must connect to the suitable pinned APC mate, type 1 map defines the return routes. Keep the module distinct from OS2 and 16-fiber versions so a visually comparable connector does not lead to an invalid test setup.

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 this optical path seen by the receiver and should be considered before diagram conclusions about a marginal port. Use this module for controlled port checks, then confirm the installed optical channel individually with its actual passive components.

Storage and repeated test cycles

This module is specified for 50 mating cycles. Its loop and total length have defined mechanical tolerances, but those dimensions do not permit sharp bending or pulling by this 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 when ordering the 24-fiber OM4 Type 1 loopback. State unit count and any asset-label needs; for procedures requiring Type 2 or a different fiber mode, ask for the custom map instead of substituting this version. Our UAE project support can review the requirement with Shenzhen production before a formal quotation is issued.
