Customized 16/24 Fibers MMC Fiber Loopback Module

Projects in the Philippines benefit from keeping the configuration, branch identification and installation requirement consistent across every participating site. The customized LPM-MMC loopback product line covers 16-fiber and 24-fiber MMC modules in OM4 or OS2, with Type 1 or Type 2 mapping. Each uses a female APC MMC interface, a 100mm nominal fiber loop and a 250mm nominal overall length. This configurable approach allows the test module to match the hardware’s actual lane map instead of forcing one standard loopback into every practice.

• Fiber Mapping: Type 1/Type 2

Specifications

Four choices that define the correct module

A useful order specifies fiber mode, mapping, connector interface and fiber count as one system. Whereas Type 1 and Type 2 change the return optical routes, sixteen-fiber and 24-fiber ferrules organize lanes differently. OS2 and OM4 should ideally be chosen for the intended test environment. The female APC connector remains non-pinned and requires the right pinned mate.

Performance varies with the selected fiber count

Insertion loss is 0.7dB maximum across the product line. 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. Validate the final values on the chosen design’s documentation.

Building a traceable diagnostic toolkit

Custom modules should carry explicit tags showing mapping, fiber count and mode, not just the MMC name. This prevents accidental cross-use between equivalent-looking test patch leads. Review the end face before each session, respect the 7.5mm bend minimum and store every module capped. Loopback testing complements, rather than replaces, end-to-end optical path certification.

Ordering and Factory Support

Use LPM-MMC as the product line reference and list 16 or 24 fibers, OM4 or OS2, and Type 1 or Type 2 mapping. State unit count and labeling criteria; a port-map excerpt is the most reliable way to validate the requested loopback. Customers in the Philippines can include multi-site labeling or documentation requirements when requesting a project quotation.
