This document discusses optical fiber connectors. It begins by introducing the ferrule, which is a cylindrical tube used in connectors to precisely align the fiber cores. The document then covers the major types of connectors that have been introduced, including ST, SC, LC, FC . A fiber optic connector is a mechanical device used to align and join optical fibers, enabling light to pass through with minimal loss. The fiber connector types, sometimes referred to as terminations, link fiber optic cables together through terminals, switches, adapters, and patch panels, by bridging the gap between their. π¦ For purchasing, use the RP Photonics Buyer's Guide for fiber connectors.
