Abstract
An optical switch having a housing and optical fibers connectable to a light source and a light detector. The light source and light detector are located remote from the housing. The first and second light guide cables have distal ends positioned in a separator assembly and are optically aligned but separated by a gap. The switch includes a device to modify a light beam, and the device is usually adapted to removably occupy the gap. The switch may be embodied in a float.
Claims6
A fiber optic cable, said cable comprising an outer cylindrical waterproof sheath having a hollow interior, an inner wrapping positioned in said hollow interior adjacent and contacting said outer sheath, a filler material disposed within said inner wrapping, and an optical fiber, said optical fiber disposed within and contacting said filler material, said filler material comprising hair-like fibers with sufficient air spaces between said hair-like fibers to allow said optical fiber to move within and with respect to said hair like fibers when said fiber optic cable is bent, and where said outer sheath is slidable with respect to the inner wrapping, whereby said outer sheath is easily strippable from said inner wrapping.
