8 Fibers MTP Female 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.

Applications
Loopbacks are used daily in manufacturing test, data center commissioning and RMA diagnosis. This module gives a fast pass/fail indication for multi-fiber ports without needing a second transceiver or a traffic generator.
Using the Loopback Correctly
Loopback testing isolates faults quickly: if the link comes up with the loopback installed, the port and transceiver are healthy and the problem lies in the cabling or far end. If it does not, the fault is local. This simple test saves hours of guesswork during commissioning.
Ordering Information
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.
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.
Quality and Testing
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.
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.
