Spacing between communication optical cables and power cables
The National Electrical Code establishes specific minimum distances when communications cables must run near power and light circuits. This practice is mandatory for two distinct reasons: ensuring the safety of the structure and its occupants, and preserving the integrity of sensitive data. Maintaining proper separation between power, data, and limited energy cabling is foundational to system performance, safety, and code compliance. Cable design and placement are very important to ensure that electromagnetic interference (EMI), or dangerous levels of electrical energy are not induced into.
