Method and apparatus for constructing an optical fiber cable which is resistant to high temperatures and is perfectly watertight, and cable produced by such process

摘要

An improved process for producing a protected optical fiber cable and the cable produced thereby. The process for producing the cable includes the insertion of a relatively thin optical fiber within a relatively large metal tube by means of flowing a fluid around the fiber and through the tube. As the water flows within the tube, the optical fiber becomes progressively entrained within the tube. Additional steps of coating the fiber with a releasable protective coating and unwinding the fiber from a reel within a container are also disclosed.
