Fiber optic cable with improved flexibility, low temperature and compression resistance

摘要

A multi-tube optical fiber cable has a core (10) with a first set of one or more optical fiber tubes (14), each having one or more optical fibers (16) loosely arranged therein. The first set of tubes (14) is constructed of a polymer having a low Young's constant modulus. The core (10) also includes at least two strength members (18) with a first binder (20) arranged around the first set of optical fiber tubes (14) and the strength members (18), where the first binder is substantially flat in shape such that there is no deformation of the first set of tubes (14), and where the strength members (18) are offset from a central axis of the cable. The cable maintains a second set of a plurality of optical fiber tubes (14), each having one or more optical fibers loosely arranged therein, arranged around the outer circumference of the core.
