What should be done to secure fiber-optic cable at coaxial cable expansion loops?

Securing fiber-optic cable at coaxial cable expansion loops with plastic cable ties or support straps is the best practice to ensure the cable is held firmly while accommodating any necessary movement for expansion without causing damage.

Plastic cable ties or support straps are specifically designed to provide the correct amount of hold without placing excessive stress or pressure on the fiber-optic cable. Unlike metal clamps, which could potentially crimp or damage the delicate structure of fiber-optic cables, plastic fasteners offer a gentle grip. This is especially important for fiber-optic cables that can be sensitive to bending or tension.

Additionally, securing the cable properly helps to prevent it from becoming loose or becoming affected by environmental factors, which could lead to signal loss or damage over time. It strikes a balance between stability and the necessary allowance for movement due to temperature changes, making it the appropriate choice for this scenario.
