Applications
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.
Using the Loopback Correctly
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.
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
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.
Logistics
Most orders leave our facility within a few working days. Courier, air freight and sea freight are all available, and we are happy to hand goods to your nominated forwarder in China.
Quality and Testing
Our test routine covers insertion loss, return loss and ferrule end face inspection on every assembly. Because testing is done in-house, custom variants receive exactly the same verification as standard models.
