Abstract
A sensor array includes a fiber optic cable and at least one electro-optical conversion unit connected to the cable. The electro-optical conversion unit includes a housing formed of mating upper and lower covers. The housing includes an interior cavity for receiving a phase modulator module, a strength member and an interferometer formed by fibers connected to various splices and couplers in combination with the phase modulator module. The interior of the housing is filled with a fill material for holding the position of optical fibers to thereby protect against environmental factors such as shock and moisture.
