SC Fiber Optic Fast Connector LX21 SC/APC SC/UPC FTTH Field Installable Quick Connector Single Mode Optical Fiber Fast Connector

Technical specifications

The LX21 SC Fiber Optic Fast Connector is a professional field-installable connector designed for fast and reliable fiber termination in FTTH, FTTx, CATV, telecommunications, and data communication networks. Available in both SC/APC and SC/UPC versions, it offers flexible deployment options for different network requirements.

Featuring a high-precision pre-polished ceramic ferrule and advanced mechanical splice technology, the LX21 allows quick on-site installation without the need for fusion splicing, epoxy, or polishing. This significantly reduces installation time and labor costs while ensuring stable optical performance.

The connector is compatible with FTTH drop cables, indoor optical cables, and tight-buffer fibers. With low insertion loss, high return loss, and excellent mechanical durability, the LX21 is an ideal solution for fiber optic network construction, maintenance, upgrades, and emergency repairs.

Whether used by telecom operators, internet service providers, contractors, or system integrators, the LX21 Fast Connector delivers reliable and cost-effective fiber connectivity.
