Rotary fiber optic switch.

摘要

Light signals are channeled through a fiber optic input cable (16) and to a rotary fiber optic switch. A rotatable drum (10) distributes the light signals to intended output locations by means of light conductive elements (13e) in the drum. Selecting the desired position of the drum by means of a detent switch or by mechanically rotating the drum through electromechanical means determines the channel orientation of the device. The output signals emerge from the light conductive elements in the drum and are transmitted to one or more output fiber optic cables (21).
