24 Fibers MTP Male Type 1 Fiber Loopback Module, OS2

This 24 loopback module provides a compact optical self test for parallel ports. It routes transmit lanes back to the receive lanes inside a rugged housing, so you can verify port function, run burn-in tests and diagnose link faults without a second device.

Applications
Keep this loopback in the toolkit for commissioning and maintenance. It is used to exercise ports during burn-in, to isolate whether a fault sits in the transceiver, the cabling or the far end, and to confirm repairs before a link goes back into service.
Using the Loopback Correctly
A loopback contains no electronics: it simply connects transmit fibers to receive fibers inside the housing. The port under test sees its own signal returned, so link indicators and diagnostics behave as if a far-end device were connected. Always check the required attenuation for high power interfaces.
Ordering Information
To order, quote LPM-SM-24MTP together with the length and quantity you need. Private labeling, custom packaging and project specific documentation are all handled in-house.
Logistics
Standard configurations normally ship within a few working days by DHL, UPS, FedEx, TNT or EMS. For project quantities we arrange air or sea freight, and we can ship on your own courier account or deliver to your appointed forwarder.
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
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.
