When pulling fiber optic cable, the pull string shall not be connected to the ___.

When pulling fiber optic cable, it is essential to avoid attaching the pull string to any component of the fiber optic cable that could be damaged during the pulling process. The buffer coating, fiber core, and cladding are all critical components of the fiber optic cable.

The buffer coating serves as protection for the fiber core, while the fiber core is the central component that transmits light signals. The cladding surrounds the fiber core and helps reflect light back into the core. Pulling on any of these components can introduce stress and potentially harm the delicate structure of the fiber optic cable, leading to signal loss or complete failure of the cable.

Therefore, the practice is to ensure that the pull string is not connected to any part of the cable's construction to maintain the integrity of the fiber and ensure proper functionality. This understanding underscores the importance of proper cable handling techniques in the installation and maintenance of fiber optic systems.
