EXTREME ENVIRONMENT OPTICAL FIBER CABLE WITH CRACK-RESISTANT LAYER

摘要

A high-temperature and crack resistant optical communication cable is provided. The cable includes an extruded cable body formed from a polymer material defining a channel within the cable body. The cable includes a plurality of optical transmission elements located within the channel. The cable includes a reinforcement sheet wrapped around the plurality of optical transmission elements. The cable includes an adhesion barrier wrapped around the wrapped reinforcement sheet. The adhesion barrier layer is a substantially uninterrupted adhesion barrier layer such that the adhesion barrier layer acts to prevent substantial adhesion between the polymer material of the cable body and an outer surface of the wrapped reinforcement sheet.

1. A high-temperature and crack resistant optical communication cable comprising:
an extruded cable body formed from a polymer material, the cable body having an inner surface defining a channel within the cable body; a plurality of optical transmission elements located within the channel; a reinforcement sheet having a first lateral edge and an opposing second lateral edge, the reinforcement sheet wrapped around the plurality of optical transmission elements such that the first lateral edge of the reinforcement sheet overlaps the second lateral edge of the reinforcement sheet forming a reinforcement overlap portion; and an adhesion barrier layer having a first lateral edge and a second lateral edge, the adhesion barrier layer wrapped around the wrapped reinforcement sheet such that the first lateral edge of the adhesion barrier layer overlaps the second lateral edge of the adhesion barrier layer forming an adhesion barrier overlap portion, wherein the adhesion barrier layer is a substantially uninterrupted adhesion barrier layer such that the adhesion barrier layer acts to prevent substantial adhesion between the polymer material of the cable body and an outer surface of the wrapped reinforcement sheet.
