Abstract:

Fiber optics is a rapidly maturing technology that offers an attractive approach to underwater communications between moving platforms. The very small diameter of an optical fiber, combined with its inherent high signal bandwidth, permits the construction of rugged, high-bandwidth, fiber optic micro cable designed for deployment from moving undersea vehicles. Micro cable is strengthened optical fiber that is capable of surviving the stresses of underwater deployment with only a minimal increase in diameter and weight. Because of its small diameter 0.7-1.0 millimeter, it is possible to coil a long length of fiber optic micro cable into a compact deployment canister for storage aboard a vehicle and subsequently deploy the communications link underwater. Fiber optic micro cable has been deployed reliably at high speed in the ocean from torpedoes. Technology currently exists to permit bidirectional, high-bandwidth signals to be transmitted over fiber optic micro cable for 100-200 kilometers without requirement for deployed optoelectronic repeaters. Several advanced system concepts are discussed that utilize the compact storage volume and the long standoff range that a fiber optic micro cable communications link can provide. Reprints.
