SC Fiber Optic Fast Connector LX31 – SC/APC & SC/UPC FTTH Field Installable Quick Connector for Single Mode Fiber
Technical specifications
The LX31 SC Fiber Optic Fast Connector is a high-performance, field-installable connector designed for fast, reliable fiber termination in FTTH, FTTx, CATV, LAN, and telecommunication networks. It is available in both SC/APC (green) and SC/UPC (blue) versions to meet different network requirements.
Featuring a pre-polished zirconia ceramic ferrule and advanced mechanical splice technology, the LX31 enables quick on-site installation without fusion splicing, epoxy, or polishing. It ensures low insertion loss, high return loss, and stable mechanical durability, making it ideal for new fiber deployments, network maintenance, and emergency repairs.
The LX31 supports FTTH drop cables, tight-buffer fibers, and indoor/outdoor optical cables, offering a compact, durable, and cost-effective solution for modern fiber optic networks.
