Which two factors are critical for a successful installation of fiber-optic cable?

For a successful installation of fiber-optic cable, cable pulling tension and bend radius are critical factors to consider. Pulling tension refers to the force applied to the fiber-optic cable during installation; exceeding recommended tension limits can damage the fibers, leading to decreased performance or complete failure. Properly managing this tension ensures that the delicate fibers within the cable remain intact and functional.

Bend radius indicates the minimum radius the fiber-optic cable can be bent without incurring damage. Fiber-optic cables are sensitive to bends; exceeding the recommended bend radius can result in transmission loss or physical damage to the fiber. Ensuring that both the cable pulling tension and bend radius are adhered to is vital for maintaining the integrity and performance of the installed fiber-optic network.

In contrast, while factors such as temperature, humidity, cable length, installation time, cable color, and type may play roles in installation logistics or environmental suitability, they are not as critical as ensuring the correct tension and bend radius to protect the fiber optics from damage during and after installation.
