MPO/MTP Fiber Loopback – High-Density Multi-fiber Self-Loop Test
Module
This MPO/MTP fiber loopback module features an integrated patch
cord that fixes both ends of the optical fiber into a single
MPO/MTP connector, transmitting optical network signals from
transmitter to receiver within the same connector to create an
optical loop. Designed for fiber optic testing applications and
network restoration, it enables effective testing and evaluation of
individual components, interfaces, and network segments.
Robust Outer Sheath Design
The fiber is protected by a simple yet strong outer sheath that
prevents fiber exposure while providing anti-bending and
anti-press-off protection.

High-Quality Ferrules with Dust Protection
Features precision-selected ferrules with professional grinding
technology for accurate docking, ensuring stable transmission and
high-efficiency connection. Each loopback includes a dust cap to
prevent contamination and maintain cleanliness.
