What is an overhead communication fiber optic cable
Because the effect of dispersion increases with the length of the fiber, a fiber transmission system is often characterized by its bandwidth–distance product, usually expressed in units of ·km. This value is a product of bandwidth and distance because there is a trade-off between the bandwidth of the signal and the distance over which it can be carried. Overhead fiber optic cable also known as aerial fiber optic cable is fiber optic cable installed on poles. The light is a form of carrier wave that is modulated to carry information. It provides high tensile strength, good performance of mechanical and temperature, and low-cost installation.
