When preparing a fiber-optic cable for splicing, why is it important to remove the jacket and armor?

Removing the jacket and armor from a fiber-optic cable is essential for properly accessing the optical fibers inside the cable. The cable is typically constructed with multiple layers, including the jacket and armor, which serve to protect the sensitive fibers during installation and use. However, when preparing for splicing, it is necessary to expose the fibers themselves, allowing the technician to access the rip cord and check the cutting depth, which is critical for properly trimming the fibers to the correct length for a successful splice.

Accessing the rip cord is particularly important because it ensures that the outer layers are removed without damaging the inner fibers. Checking the cutting depth ensures that the fibers are stripped to the right length, maintaining optimal performance in signal transmission once they are spliced. Thus, the focus on safe and accurate fiber exposure underscores the importance of this step in the splicing process, preventing potential issues that could arise from improper handling.
