An undersea lightwave surveillance system combining technical advances in electronics and photonics is being developed and tested for the US Navy to detect and precisely locate submarines and surface vessels at great distances. The surveillance system provides increased signal clarity and sensitivity to increasingly quieter targets in the ocean. The undersea surveillance program is based on a fixed, distributed, integrated system using a new lighter-weight advanced optical fiber cable that would run thousands of miles along the ocean's floor. The new cable, smaller in diameter than commercial telecommunications optical cable, is hooked to integrated multiplexer/repeater units and a series of acoustic hydrophones, including a new, small, variable reluctance device. Successful advanced development testing of this AT&T Bell Laboratories system has been conducted.
