On the “pulling out” of optic fibers from the sleeve in a cable with a central module

A comparative analysis of the designs of aerial optical cables is conducted. It is shown that self-supporting designs with strength elements made of high-molecular-weight threads have undeniable advantages in terms of design and operational characteristics compared to cables with a central module. It is concluded that the main reason for the "pulling out" of optic fibers from the optical sleeve into the module is the effect of gravity in a suspended single-module cable. It has been shown that a properly implemented amount of excess fiber length in a single-module cable and presence of the necessary technological reserve of cable at the splice closure will help to avoid the “pulling” of optical fibers. Practical recommendations are given for protecting against the “pulling” of optical fibers from the splice closure into the module during the technical operation of communication lines.
