METHODS OF CONTROLLING JACKET BONDING WITH CABLE ARMOR AND WATER BLOCKING AT STRENGTH MEMBERS

摘要

A method of making an armored cable having a polymer covering where the bond between the armor and the covering is controlled by introducing particulate matter at the interface of the armor and covering. A filler material is applied to the exterior surfaces of the cable strength elements in order to inhibit the formation of voids in the polymer covering that would otherwise promote water migration along the cable.

主权项

1. A method of making an armored fiber optic cable, comprising:
providing a fiber optic cable core, the fiber optic cable core including at least one optical fiber capable of conveying optical signals; at least partially enclosing the fiber optic cable core in armor; applying particulate matter to an exterior surface of the armor; providing at least one strength element; applying a filler material to the at least one strength element; and after applying the particulate matter, forming a covering over the armor, wherein the at least one strength element is adjacent to the exterior surface of the armor and at least partially embedded in the covering, the filler material contacting the armor.
