Customized 16/24 Fibers MMC Fiber Loopback Module

Malaysian upgrade projects can use this configuration where its interface and fiber map align with both the installed cabling and the new hardware. The project-specific LPM-MMC loopback family covers 16-fiber and 24-fiber MMC modules in OM4 or OS2, with Type 1 or Type 2 assignment. Every uses a female APC MMC interface, a 100mm nominal fiber loop and a 250mm nominal complete length. This configurable approach makes it possible for the test module to match the connected hardware’s actual lane layout instead of forcing one standard loopback into each procedure.

Specifications

Four choices that define the correct module

A valuable order specifies fiber mode, assignment, connector interface and fiber count together. While Type 1 and Type 2 change the return paths, sixteen-fiber and 24-fiber ferrules organize lanes differently. OS2 and OM4 should be chosen for the intended test setup. The female APC connector remains non-pinned and requires the intended pinned mate.

Performance varies with the selected fiber count

Insertion loss is 0.7dB maximum across the family. Return loss is specified at 60dB minimum for 16-fiber versions and 40dB minimum for 24-fiber versions. G.657.A2 glass and a 2.5mm OFNP jacket are used, with 50-cycle mating durability. Determine the final ratings on the chosen configuration’s documentation.

Building a traceable diagnostic toolkit

Made-to-order modules ought to carry clear labels showing mode, assignment and fiber count, not just the MMC name. This prevents accidental cross-use between similar-looking test cords. Inspect the end face before every session, observe the 7.5mm bend minimum and store each module capped. Loopback testing complements, rather than replaces, end-to-end channel certification.

Ordering and Factory Support

Use LPM-MMC as the family reference and provide 16 or 24 fibers, OM4 or OS2, and Type 1 or Type 2 assignment. Document unit count and labelling requirements; a port-layout excerpt is the most reliable way to determine the requested loopback. For Malaysian upgrades, our team can compare the requested build with the existing environment before production begins.
