Abstract:

Fiber optic cable is vulnerable to its environment more than conventional metallic cables. In addition to the required mechanical properties, adequate moisture and rodent protection are necessary, especially in direct burial applications. In such application optical fibers can experience stress due to moisture freeze-up and the small diameter of the cable makes it an easy prey for rodents. All these protections can obviously be achieved by designing layers of jackets, each of which has its own function. The major drawback of such construction though is not only economic but also performance. In this paper a jacketing concept is discussed whereby two layers of jackets -moisture protection through corrugated steel and polyethylene can be replaced by a single jacket comprising longitudinally formed steel tape bonded to polyethylene.
