This 12 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.

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.

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.

To order, quote LPM-SM-12MTP together with the length and quantity you need. Private labeling, custom packaging and project specific documentation are all handled in-house.

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.

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 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.
