Which of the following practices helps prevent damage during fiber optic installation?

Maintaining proper pulling tension is a crucial practice in fiber optic installation that helps prevent damage to the fiber. When fiber optic cables are installed, they cannot be pulled too tightly, as excessive tension can cause microbends or macrobends, leading to increased loss of signal strength or even physical damage to the fibers themselves. Adhering to the manufacturer's specified pulling tension ensures that the integrity of the fiber is preserved, allowing it to function correctly once installed.

In contrast, using a wet environment can introduce moisture that may lead to corrosion or other damage to the fiber optic cables. Avoiding the minimum bending radius is detrimental as bending the fiber beyond its specified limits can permanently damage the fibers and disrupt signal transmission. Exposure to direct sunlight can degrade certain types of fiber optic cables over time, as UV radiation may damage the outer jacket of the cable, potentially exposing the fibers to external factors that can compromise performance. Therefore, maintaining proper pulling tension is essential to safeguarding the fiber optic cable during the installation process.
