This 16 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.

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
Ordering is simple: send us LPM-SM-16MTP and your required lengths and quantities, and we return a factory quote the same working day. Small trial orders are welcome before you commit to a full project rollout.
How We Pack
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.
Quality and Testing
We do not ship untested product. Each unit is measured on calibrated equipment for optical performance and visually inspected for end face quality before packing. Batch traceability is maintained so any field issue can be tracked back to production.
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.
