EspañolOPTICAL FIBER CONNECTOR
(Redirected from ST connector)
An 'optical fiber connector' terminates the end of an optical fiber, and enables quicker connection and disconnection than splicing. The connector aligns the core of the two fibers so that light can pass, and provides a mechanical coupling to hold it together. A variety of optical fiber connectors are available. The main difference between connectors is in the dimensions and the mechanical coupling.
If the fiber-end is angled to reduce back reflections this is usually described by adding APC (Angled Physical Contact) to the name.
★ FC floating ferrule provides good mechanical isolation; However, it is screwed into contact which can induce scratches on the fiber.
★ SC connector offers excellent packing density, and its push-pull design resists fiber end face contact damage during connection.
★ In general the insertion loss should not exceed 0.75 dB and the return loss should be higher than 20 dB. Typical insertion repeatability, the difference in insertion loss between one plugging and another, is 0.2 dB.
★ ST connectors have a key which prevents rotation of the ceramic ferrule and bayonet lock similar to a BNC shell.
★ LC connectors are replacing SC connectors in corporate networking environment due to its smaller size.
★ On all connectors, cleaning the ceramic ferrule before each connection helps prevent scratches and extends the connector life substantially.
