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-OM4-24MTP 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.
Built to Your Spec
As a factory we can modify almost every detail of this product: length, jacket material and color, polarity, gender, breakout geometry, labeling and packaging. Non-standard variants are routine work for us, not a special project.
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.
