Paper Abstract

A rotary single-mode optical fiber switch has been developed which uses a novel anti-backreflection geometry. As a result the return loss is greater than 50 dB while insertion loss is maintained below 1 dB. This paper will indicate applications in the subscriber ioop then detail the rotary switching concept anti-backreflection enhancement and electromagnetic actuator. The switch will be shown to be rugged under the environmental conditions that may be expected in the outside plant.
