Which NEC article covers optical fiber installation?

• A. 725
• B. 770
• C. 805
• D. 600

Answer: (B)

Optical fiber installations are covered by a dedicated section of the NEC, Article 770. This article specifically addresses optical fiber cables and systems, outlining the requirements for installing, splicing, terminating, connecting, and protecting fiber optic cables used for communications. The reason this article is the best fit is that fiber optics have unique properties and handling needs—such as precise terminations, bend radii, and protection considerations—that aren’t the same as copper or other low‑voltage communication methods. Other articles cover different topics, like low‑voltage Class 2/3 circuits or general communications cabling, which don’t address the specialized installation rules for fiber optic systems.
