12 Fibers MPO Female Type 1 Attenuated Fiber Loopback Module, OS2, 3dB

Our 12 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
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
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-12MPO in your enquiry. Our sales team can also advise on polarity, gender and jacket choices if your project documentation is not final yet.
Logistics
We dispatch worldwide by international courier, with air and sea freight options for bulk orders. Goods can be sent collect on your courier account, and documentation for customs clearance is provided with every shipment.
How We Pack
Products are packed in anti-static or PE bags with connector dust caps fitted, then boxed in sturdy export cartons. Custom labels, barcodes and carton markings are available on request.
Built to Your Spec
Our engineering team handles custom MPO/MTP assemblies daily. If the standard configuration does not match your link design, send us the requirement and we will build exactly what your network needs at factory-direct cost.
