ABSTRACT:
A plurality of optical sensors are mounted to a housing made of optically conductive material. The housing seals the optical sensors from a water-filled tube which extends through said housing. The optically conductive material provides optical coupling with the water-filled cable tube whereby a plurality of light beams are directed through the housing and the water-filled tube in a predetermined pattern, which provides certainty of the absence or presence of a cable within the water-filled cable tube for a minimum cable diameter regardless of the orientation of the cable within the water-filled tube.
