Abstract
The present invention relates to an optical-fiber switch. The switch is used in switching between at least two optical signals which are capable of being modulated with a broadband RF signal including digital signals. The switch is comprised of at least two optical-fiber cables for feeding the at least two optical signals to at least two fixed positions. An optical-fiber output cable is provided having one end which is movable between at least two positions which are directly adjacent said two fixed positions. A drive unit is provided for moving the optical-fiber output cable between the at least two positions, whereby the optical signals are selectively fed to the optical-fiber output cable.
