1550nm 3.0mm ST Fiber Optic Connector with Low Insertion Loss for Pre Assembly Components
ST connectors were among the first connector types widely implemented in fiber optic networking applications. Originally developed by AT&T, ST stands for 'Straight Tip' connector.
The ST connector utilizes a 2.5mm ferrule with a round plastic or metal body. The connector features a reliable "twist-on/twist-off" bayonet-style lock mechanism for secure connections.
Optical fiber connectors provide essential connect/disconnect capability for fiber optic systems. These connectors are typically assembled and polished in manufacturing facilities, though field termination is also possible for applications such as patch panel installations.
Common applications include telephone exchanges, customer premises wiring, outside plant installations, equipment connections, and cable cross-connections. Most optical fiber connectors are spring-loaded to ensure fiber faces press together when mated, eliminating signal losses from air gaps.
