8 Fibers MTP Male Type 1 Fiber Loopback Module, OS2

This 8 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.

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.

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.

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.

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.

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.
