Key Features

Engineered For Performance

Push-Pull Snap-In Design

Simple push-pull coupling requires no twisting or threading, enabling fast and reliable connections with audible click confirmation for proper seating.

Precision Zirconia Ferrule

2.5mm zirconia ceramic ferrule with sub-micron concentricity ensures consistent low-loss performance and excellent repeatability across thousands of mating cycles.

Universal Compatibility

SC is the most widely deployed connector type in FTTH and telecom networks worldwide, ensuring broad compatibility with splitters, OLTs, ONUs, and patch panels.

Color-Coded Identification

Blue housing for UPC single mode, green for APC single mode, and beige for multimode — enabling quick visual identification and preventing cross-connection errors.

Typical Applications

01

FTTH / PON Networks

Standard connector type for GPON/EPON optical line terminals, splitters, and optical network units in fiber-to-the-home deployments.

02

Fiber Distribution Frames

SC adapters and connectors in ODF panels and fiber distribution hubs for telecom central office and outside plant cross-connect applications.

03

CATV & Broadcast Networks

SC/APC connectors in analog and digital CATV head-end equipment where high return loss is critical to prevent optical reflections and signal distortion.
