ST Connector

ST is the abbreviation of “Stab & Twist” or “Straight Tip”. ST connector has a bayonet style mount, and a 2.5 mm long cylinder of ceramic (common) or polymer ferrule to accommodate the entire fiber. The installation method is similar to a snap-on light bulb, and it is inserted and rotated half a turn to the bayonet. The core of the ST connectors is exposed.
The ST fiber connector was developed by AT&T, and its main parameters are equivalent to those of FC and SC connectors. Straight Tip ST connectors usually used in multi-mode device connections, and are often used in ODF(optical distribution frames). For 10Base-F connections, the connector is usually ST type.
