OPTICAL FIBER CABLE WITH BONDED CORE ELEMENTS

摘要

An optical communication cable and related systems and methods are provided. The optical cable includes a plurality of wrapped core elements, and the outer surfaces of adjacent wrapped core elements are joined together by discrete bond sections. The discrete bonds sections may be structures such as laser welds, ultrasonic welds, or adhesive material. The discrete bonds hold the wrapped core elements together in the wrapped pattern, such as an SZ stranding pattern.

主权项

1. An optical communication cable comprising:
a cable body including an inner surface defining a passage in the body; a first core element located in the cable body, the first core element comprising:
a first tube having an inner surface defining a bore and an outer surface; anda first optical transmission element located within the bore of the first tube; a second core element located in the cable body, the second core element comprising:
a second tube having an inner surface defining a bore and an outer surface; anda second optical transmission element located within the bore of the second tube;wherein the first core element and the second core element are wound around a central area of the passage such that the first and second core elements are adjacent to each other defining an interface between the outer surfaces of the first and second tubes, wherein the interface extends at least a portion of a length of the cable body; and a plurality of discrete bonded sections joining the outer surface of the first tube to the outer surface of the second tube at discrete sections along the length of the interface such that the first tube and the second tube are held relative to each other following winding, wherein unbonded sections of the outer surface of the first tube and of the outer surface of the second tube are located between adjacent bonded sections along the length of the interface.
