What type of cables and raceways does Article 770 discuss?

Article 770 of the National Electrical Code (NEC) specifically addresses the installation and appropriate use of optical fiber cables. This article outlines the requirements for the installation of these types of cables, which are essential for high-speed communication systems and networking applications. Optical fiber cables transmit data as light signals, providing significant advantages over traditional copper cabling, including higher bandwidth capabilities and lower susceptibility to electromagnetic interference.

The provisions in Article 770 include guidelines on the different types of optical fiber cabling, their fire safety ratings, and specific installation practices to ensure proper performance and safety. This includes considerations for bending radii, conductor placement, and the use of raceways or conduits that accommodate optical fiber installations.

While other options might be related to electrical installations, they do not fall under the specific focus of Article 770. This makes the understanding of optical fiber cables and their proper installations vital for compliance with NEC regulations in any project utilizing such technology.
