12 Fibers MTP Male Type 1 Fiber Loopback Module, OS2

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.

Product Highlights

• Fiber Type: OS2 9/125μm
• Fiber Connector: MTP® Male, APC
• Insertion Loss: SM (G657.A2)≤1.5dB
• Return Loss: SM≥50dB
• Insert-Pull Test: 50times
• Factory tested, individually packed

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.

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.

Please reference LPM-SM-12MTP in your enquiry. Our sales team can also advise on polarity, gender and jacket choices if your project documentation is not final yet.

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.

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.

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.
