What is the reason for removing approximately 2.5 cm (1 inch) of jacket and armor from a fiber-optic cable?

Removing approximately 2.5 cm (1 inch) of jacket and armor from a fiber-optic cable primarily serves the purpose of exposing the cable's rip cord, which is essential in the preparation process for splicing or termination. The rip cord is typically located underneath the outer jacket and allows for easier stripping of the cable without damaging the fibers inside. By removing just the right amount of jacket and armor, technicians can also ensure they have the correct knife depth for safely cutting through the jacket without risking harm to the inner fiber elements. This preparation is crucial for achieving a clean and effective splice or termination, leading to better performance and reliability in fiber optics installations.
