8 Fibers MTP Female Type 1 Fiber Loopback Module, OS2

Our 8 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® Female, APC
• Insertion Loss: SM (G657.A2)≤1.5dB
• Return Loss: SM>50dB
• Insert-Pull Test: 50times, IL Change<0.5dB
• Factory tested, individually packed

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.

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-8MTP 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.

Most orders leave our facility within a few working days. Courier, air freight and sea freight are all available, and we are happy to hand goods to your nominated forwarder in China.

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.
