To achieve optimal performance, how should fiber-optic cables be installed regarding pulling tension?

Achieving optimal performance in fiber-optic cable installation involves adhering to recommended tension limits during the pulling process. Fiber-optic cables are sensitive to tension because excessive stress can lead to microbending and macrobending, which adversely affects signal transmission and can even result in permanent damage to the fibers.

The recommended tension limits are established based on the cable's specifications and are designed to balance the need for the cable to be securely installed without compromising its integrity. Following these guidelines helps maintain the physical characteristics of the fiber and ensures the system’s reliability and performance over time.

In contrast, using excessive tension may lead to physical damage of the fibers, while minimal or no tension could result in loose installations that might not meet the required performance standards. Thus, understanding and applying the appropriate tension limits is crucial for successful fiber-optic installation.
