Is fiber optic cable installation considered low-voltage wiring
Yes, fiber optic cabling is classified as low voltage, but with an important caveat—it doesn't transmit electrical voltage at all. The National Electrical Code (NEC), specifically Article 770, regulates the installation of fiber optic systems. While fiber optics operate under the umbrella of low-voltage systems, they differ fundamentally from. Whether you're building new or upgrading your existing systems, fiber optic cabling and low voltage wiring are essential components to keep your operations fast, secure, and scalable. Standard power outlets in the United States and Canada carry 120V, and most lighting fixtures, electronics, and devices draw up to 120V. Voltage classifications can be confusing.
