Teijin Aramid has unveiled its Twaron Tape, which features an aramid fiber matrix construction that allows it to protect optical fiber cables with diameters as small as 1.2 mm. The company claims the tape offers 3x to 5x better crush resistance than current aramid fiber protection. The Twaron Tape D2800 is billed as a robust, flexible, patented protection approach that helps increase cable production speed. The tape’s flexibility may also enable quicker, more convenient installation and handling, claims Teijin, as well as easier stripping and connectorization of optical fiber cables.
The tape consists of a single, spread Twaron yarn that is impregnated and fixed with a matrix material. This design results in significant space savings and enables optical fiber cables to be very thin, says the company. To provide complete coverage and optimal force and crush resistance, the tape is evenly wrapped around the core of an optical fiber cable. According to Teijin, the production of thinner cables using Twaron Tape offers several advantages. Use of 1.2-mm cables translates into an increased capacity for optical distribution frames of 30-50%, as compared to 1.6-mm cables; further, thinner cables demand less cooling power, thereby cutting costs -- and emissions -- at distribution centers.
Christoph Hahn, commercial director at Teijin Aramid, comments, “We are one of the early pioneers of reinforcement technology for fiber-optic cables, and as this market has developed, we have gained an in-depth understanding of the market requirements. We are proud to contribute to this industry by offering our knowledge in high performance aramid fibers to our worldwide partners.”
