An optical fiber cable includes a plurality of loose tubes, each of which contain at least one optical fiber therein. The loose tubes are constructed of a polymer with the tubes arranged in at least two layers, each of which are rotated in the same uni-helical direction and are ranged having substantially the same lay length. A jacket encases the loose tubes, where any one of the optical fibers in one of the loose tubes is accessible when the jacket is opened and the at least two layers are untwisted.
