12 Fibers MPO Female Type 1 Attenuated Fiber Loopback Module, OS2, 3dB
This 12 loopback module provides a compact optical self test for parallel ports. It routes transmit lanes back to the receive lanes inside a rugged housing, so you can verify port function, run burn-in tests and diagnose link faults without a second device.

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
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.
Logistics
We dispatch worldwide by international courier, with air and sea freight options for bulk orders. Goods can be sent collect on your courier account, and documentation for customs clearance is provided with every shipment.
How We Pack
