Abstract
A fiber optic switch is formed using cylindrical or biconic fibers optic connector components for axially aligning pairs of fibers to be switched. The ferrules of the connector are rotatably mounted within an alignment sleeve, such that a pair of fibers in a first ferrule may be rotated relative to a pair of fibers mounted in a second ferrule to effect a bypass switch operation. Various forms of switch actuators, including rotary and linear actuators, are disclosed, along with fail-safe arrangements.
