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
Please reference LPM-SM-12MPO in your enquiry. Our sales team can also advise on polarity, gender and jacket choices if your project documentation is not final yet.
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.
How We Pack
Products are packed in anti-static or PE bags with connector dust caps fitted, then boxed in sturdy export cartons. Custom labels, barcodes and carton markings are available on request.
Built to Your Spec
We have manufactured fiber optic assemblies since 1995. MPO and MTP cabling is one of our core lines: fiber counts from 8 to 144, single mode and multimode, UPC and APC polish, trunk, jumper, harness and breakout formats. Send your drawing and we turn it into a ready to install assembly.
