Many rules are based on the National Electrical Safety Code (NESC), which provides minimum standards for utility systems. The network of communication lines buried beneath the ground carries high-speed fiber optic internet, traditional telephone, and cable television signals. These facilities are collectively known as communication infrastructure. Knowing the exact depth of these lines is paramount for anyone planning. However, in virtually every major natural disaster, and sometimes just from the perils of age, cellular towers degrade, crumple, and collapse (fail), taking down what has become a critical piece of national communications infrastructure., at any time and without notice. Such changes will be incorportated into new. Recommendation ITU-T K. 57 specifies measures to be taken with respect to safety and risk of damage to equipment through earth potential rise when power line towers are used for locating radio base stations.

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. For example, a common multi-mode fiber with a bandwidth–distance product of 500 MHz·km could carry a 500 MHz signal for 1 km or a 1000 MHz sig.
