What is the primary purpose of removing approximately 2.5 cm (1 inch) of jacket from the end of a fiber-optic cable?

The primary purpose of removing approximately 2.5 cm (1 inch) of jacket from the end of a fiber-optic cable is to access the cable's rip cord and to check the cutting depth. By stripping the jacket, technicians can reveal the inner components of the cable, allowing them to inspect the rip cord that helps with the removal of the cable's strength members and any additional layers. This step is essential in ensuring that the subsequent stripping of the fiber itself is done accurately and without damaging the delicate fibers contained within. It provides a clear view of the layers, enabling technicians to assess if further stripping is necessary and to determine how far they can safely cut without risking damage to the optical fibers.

While preparing the cable for installation might seem related to this process, the specific action of removing the outer jacket primarily serves the purpose of accessing and verifying the internal features and structure of the cable. Enhancing flexibility or ensuring proper signal transmission are not direct outcomes of removing the jacket; these factors are influenced more by the cable design and the quality of installation practices, rather than the jacket removal itself.
