8 Fibers MTP Male Type 1 Fiber Loopback Module, OS2

A 8 loopback for testing QSFP, QSFP-DD and OSFP parallel interfaces. Plug it into the port under test and the optical signal loops back internally, making it ideal for production burn-in, RMA checks and field diagnostics.

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, 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.

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.

Each assembly is coiled, capped and sealed in an individual bag, then packed into foam lined export cartons. Test reports can be attached per unit or per batch, and carton marks follow your shipping instructions.

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.
