Fibre optic cable design with improved compression test results

摘要

A multi-tight buffer fiber optic cable (10) includes a first layer of tight buffer optical fibers (18) and at least one second layer of tight buffer optical fibers (22) surrounding the first layer of tight buffer optical fibers. A jacket (12) surrounds the at least one second layer of tight buffer optical fibers, where the first layer of tight buffer optical fibers and the at least one second layer of tight buffer optical fibers are helically wound, and where the at least one second layer of tight buffer optical fibers are helically wound in the same direction as the first layer of tight buffer optical fibers and at substantially the same lay length.
An intermediate layer of aramid yarns (16) is helically wound between the optical fiber layers.
