A 24 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.

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.
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.
To order, quote LPM-SM-24MTP together with the length and quantity you need. Private labeling, custom packaging and project specific documentation are all handled in-house.
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.
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 cable is protected with dust caps and individual packaging before being boxed for shipment. Batch test reports and your own part number labels can be included in each bag.
