The SC UPC Fast Field Connector with Mechanical Locking Mechanism is an upgraded solution designed to provide more stable fiber fixation and improved installation reliability during field termination.

This connector features an external locking sleeve that securely fixes the bare fiber after insertion, preventing fiber movement during pulling, vibration, or long-term use. Compared with standard fast connectors, the locking structure enhances mechanical stability while maintaining simple tool-free installation.

Using a pre-polished UPC ferrule and fiber pre-embedded technology, this connector supports fast on-site termination for FTTH drop cables (3.0 × 2.0 mm / 1.6 × 2.0 mm) and G.652 / G.657 single-mode fibers. It is well suited for applications where stable fiber positioning and consistent optical performance are required.

FAQ

What is the function of the mechanical locking sleeve?
The locking sleeve is used to secure the bare fiber after insertion, preventing fiber movement and improving mechanical stability during installation and long-term use.
No. The installation process remains simple and does not require fusion splicing or epoxy, only slightly longer than standard fast connectors.
Yes. The connector supports multiple reuse cycles (≥5 times) when properly unlocked and reinstalled.
