24 Fibers MTP Male Type 1 Fiber Loopback Module, OS2

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.

Applications
Typical uses are switch and NIC port validation in production, burn-in testing before shipment, troubleshooting suspect links in the field, and verifying cabling channels end to end. It lets a single technician confirm that a parallel port transmits and receives correctly on every lane.
Using the Loopback Correctly
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 Information
Please reference LPM-SM-24MTP in your enquiry. Our sales team can also advise on polarity, gender and jacket choices if your project documentation is not final yet.
How We Pack
Every cable is protected with dust caps and individual packaging before being boxed for shipment. Batch test reports and your own part number labels can be included in each bag.
Built to Your Spec
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.
Quality and Testing
Every MPO/MTP assembly leaving our factory is 100% tested for insertion loss and return loss, with end face geometry checks on the multi-fiber ferrules. Controlled polishing keeps the loss budget stable across the whole batch, which matters when several mated pairs sit in one link.
