Fiber optic cable for downhole and harsh environments

Abstract

A fiber optic cable includes a braided core defining a plurality of helical grooves, and one or more optical fibers disposed along one or more of the helical grooves of the braided core. The elongated structures braided to form the braided core are composed of braided ropes or monolithic wires. An outer layer disposed over an outer surface of the braided core is composed of a metal layer or a flexible plastic layer.

Dependencies are inferred from the claim text.
