12 Fibers MPO Female Type 1 Attenuated Fiber Loopback Module, OS2, 3dB

Our 12 loopback module is a simple, reliable tool for validating multi-fiber ports before go-live. The internal fiber path is factory measured, and the housing is small enough to keep in every field toolkit.

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
This module is passive and needs no power or configuration. Insert it into the cage until it latches, and the port can then be exercised with the switch or server diagnostics. The optical path is measured at production, and the housing protects the internal fiber from daily toolkit wear.
Ordering Information
Ordering is simple: send us LPM-SM-12MPO 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.
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.
Logistics
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.
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.
