ABSTRACT:
An optical sensor cable includes at least one light source fiber extending substantially the entire length of the cable. A plurality of optical sensors are functionally coupled at an input thereof to the at least one light source fiber. At least one signal return fiber extends substantially along the entire length of the cable and is functionally coupled to an output of each of the optical sensors. The at least one source light fiber and the at least one signal return fiber are configured to be coupled at either end thereof to a respective one of a light source and a photodetection device.
