24 Fibers MMC Female Type 1 Fiber Loopback Module, OM4

Projects in the Philippines benefit from keeping the configuration, branch identification and installation requirement consistent across every participating site. This 24-fiber OM4 loopback terminates in an MMC female APC connector and uses Type 1 fiber mapping to return transmitted lanes to the receiver. It supports multimode port diagnostics and burn-in without a second active device. The short 250mm item 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

Both fiber mode and fiber count must align with the hardware test plan. Whereas the female APC MMC interface must connect to the appropriate pinned APC mate, type 1 mapping defines the return optical routes. Keep this optical module separate from OS2 and 16-fiber versions so a visually equivalent connector is not intended to lead to an invalid test design.

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 fiber path seen by the receiver and should ideally be considered before layout conclusions about a marginal port. Use the optical module for controlled port checks, then establish the installed link individually with its actual passive components.

Storage and repeated test cycles

The optical module is specified for 50 mating cycles. Its loop and overall length have defined mechanical tolerances, but those dimensions take care not to permit sharp bending or pulling by the fiber 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 submitting a request for the 24-fiber OM4 Type 1 loopback. State unit count and any asset-label needs; for procedures requiring Type 2 or a further fiber mode, ask for the customized mapping instead of substituting the configuration. Customers in the Philippines can include multi-site labeling or documentation requirements when requesting a project quotation.
