Customized 16/24 Fibers MMC FiberCustomized 16/24 Fibers MMC Fiber Loopback Module
Singapore high-density designs should assess this item together with panel access, cable routing and the complete optical loss allowance. The custom LPM-MMC loopback range covers 16-fiber and 24-fiber MMC modules in OM4 or OS2, with Type 1 or Type 2 map. Each uses a female APC MMC interface, a 100mm nominal fiber loop and a 250mm nominal total length. This configurable approach permits the test module to match the active hardware’s actual lane mapping instead of forcing one standard loopback into every method.

Four choices that define the correct module
A practical order specifies connector interface, fiber count, fiber mode and map collectively. Sixteen-fiber and 24-fiber ferrules organize lanes differently; concurrently, Type 1 and Type 2 change the return channels. OS2 and OM4 should be selected for the intended test setting. The female APC connector remains non-pinned and requires the specified pinned mate.
Performance varies with the selected fiber count
Insertion loss is 0.7dB maximum across the range. 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. Review the final figures on the selected arrangement’s documentation.
Building a traceable diagnostic toolkit
Customized modules should carry distinct markings showing map, fiber count and mode, not just the MMC name. This prevents accidental cross-use between analogous-looking test leads. Check the end face before each session, preserve the 7.5mm bend minimum and store every module capped. Loopback testing complements, rather than replaces, end-to-end path certification.
Ordering and Factory Support
Use LPM-MMC as the range reference and document 16 or 24 fibers, OM4 or OS2, and Type 1 or Type 2 map. Give quantity and marking specifications; a port-mapping excerpt is the most reliable way to review the requested loopback. Singapore and regional project orders can be reviewed for interface compatibility, packing details and delivery coordination.
