For UAE project teams, the key is to match this exact configuration to the port schedule, optical budget and delivery documentation. The custom LPM-MMC loopback series covers 16-fiber and 24-fiber MMC modules in OM4 or OS2, with Type 1 or Type 2 map. Every uses a female APC MMC interface, a 100mm nominal fiber loop and a 250mm nominal total length. This configurable approach enables the test module to match the active equipment’s actual lane mapping instead of forcing one standard loopback into each process.

Specifications

Four choices that define the correct module

A practical order specifies fiber mode, map, connector interface and fiber count jointly. While Type 1 and Type 2 change the return routes, sixteen-fiber and 24-fiber ferrules organize lanes differently. OS2 and OM4 should be chosen for the intended test setting. The female APC connector remains non-pinned and requires the proper pinned mate.

Performance varies with the selected fiber count

Insertion loss is 0.7dB maximum across the series. 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. Verify the final figures on the chosen setup’s documentation.

Building a traceable diagnostic toolkit

Customized modules ought to carry unambiguous identifiers showing mode, map and fiber count, not just the MMC name. This prevents accidental cross-use between comparable-looking test patch cords. Examine the end face before every session, preserve the 7.5mm bend minimum and store each module capped. Loopback testing complements, rather than replaces, end-to-end link certification.

Ordering and Factory Support

Use LPM-MMC as the series reference and state 16 or 24 fibers, OM4 or OS2, and Type 1 or Type 2 map. Provide unit count and identification needs; a port-mapping excerpt is the most reliable way to verify the requested loopback. Our UAE project support can review the requirement with Shenzhen production before a formal quotation is issued.
