The recommended separation distance of 12 inches (30 cm) between different service types is based on standards and best practices intended to minimize the risk of interference between various communication systems, such as copper and fiber optic cabling, as well as power and data cables. This distance helps ensure that electromagnetic interference (EMI) and other disruptive signals do not negatively impact the performance and reliability of the cables in proximity to each other.

Maintaining a 12-inch separation creates a sufficient buffer that allows for the performance of unshielded twisted pair (UTP) cables and fiber optic cables without compromising signal integrity. This practice is crucial in data centers, telecommunication rooms, and building network infrastructures where multiple types of services may be in close proximity. It contributes to the overall efficiency of the network while also adhering to industry standards and guidelines, thus enhancing the longevity and reliability of the installed systems.
