Fiber Connectors

Fiber Connections-

Straight Tip (ST) Designation for the straight tip connector developed by AT&T. This optical connector features a physically contacting non-rotating 2.5mm ferrule design and bayonet connector to adapter mating. The bayonet housing may be metallic, or plastic. Some people call it stick and twist because that’s the motion used in attaching it to a device.

SC Connector (standard connector, subscriber connector) A fiber-optic cable connector that uses a push-pull latching mechanism similar to common audio and video cable. For bidirectional transmission, two fiber cables and two SC connector (dual SC) are used. SC is specified by the TIA as FOCIS-3.

LC Connector (Lucent Connector) A miniaturized version of the fiber-optic SC connector. It looks somewhat like the SC, but is half the size with a 1.25 mm ferrule instead of 2.5mm.
