What type of cables and raceways does Article 770 discuss?

Article 770 of the National Electrical Code specifically addresses the installation requirements and guidelines for optical fiber cables. This includes various aspects such as proper installation methods, protection against physical damage, and suitable raceways for the routing of these cables. Optical fiber cables are essential for high-speed data transmission and have unique properties and installation requirements that differ from traditional copper wiring.

The focus of this article is primarily on ensuring the safety and integrity of optical fiber installations, making it a critical part of electrical code regulations related to telecommunications and data systems. Understanding these requirements helps in maintaining industry standards and ensuring effective communication systems.

In contrast, the other options relate to different types of cabling that are governed by other articles in the NEC, which is why they do not apply to the content outlined in Article 770.
