Our 24 loopback module is a simple, reliable tool for validating multi-fiber ports before go-live. The internal fiber path is factory measured, and the housing is small enough to keep in every field toolkit.

Product Highlights

• Fiber Type: OM4 50/125μm
• Fiber Connector: MTP® Female, UPC
• Insertion Loss: MM (BIF)≤1.2dB
• Return Loss: MM≥25dB
• Insert-Pull Test: 50times, IL Change<0.5dB
• Factory tested, individually packed

Loopbacks are used daily in manufacturing test, data center commissioning and RMA diagnosis. This module gives a fast pass/fail indication for multi-fiber ports without needing a second transceiver or a traffic generator.

This module is passive and needs no power or configuration. Insert it into the cage until it latches, and the port can then be exercised with the switch or server diagnostics. The optical path is measured at production, and the housing protects the internal fiber from daily toolkit wear.

Ordering is simple: send us LPM-OM4-24MTP and your required lengths and quantities, and we return a factory quote the same working day. Small trial orders are welcome before you commit to a full project rollout.

We do not ship untested product. Each unit is measured on calibrated equipment for optical performance and visually inspected for end face quality before packing. Batch traceability is maintained so any field issue can be tracked back to production.

We have manufactured fiber optic assemblies since 1995. MPO and MTP cabling is one of our core lines: fiber counts from 8 to 144, single mode and multimode, UPC and APC polish, trunk, jumper, harness and breakout formats. Send your drawing and we turn it into a ready to install assembly.

Each assembly is coiled, capped and sealed in an individual bag, then packed into foam lined export cartons. Test reports can be attached per unit or per batch, and carton marks follow your shipping instructions.
