Which NEC article covers premises powered optical fiber broadband communications systems that provide voice, video, data, and interactive services through an optical network terminal?

• A. Article 840
• B. Article 820
• C. Article 300
• D. Article 250

Answer: (A)

The main idea is recognizing that there is a dedicated NEC section for broadband systems that are powered at the customer’s premises, including fiber to the home and the optical network terminal. That specific topic is covered by Article 840. It sets the rules for how a premises-powered broadband communications system is installed, powered, and protected on the inside of the building, including how the optical network terminal is supplied from the premises electrical system and how it interfaces with the building’s wiring. Article 840 is the best fit because it directly addresses the electrical requirements, wiring methods, power source, overcurrent protection, and coordination needed for a system that delivers voice, video, and data via an optical network terminal at the premises. The other articles don’t focus on this type of integrated broadband installation: Article 300 covers general wiring methods, Article 250 covers grounding and bonding, and Article 820 deals with communications circuits more broadly but not the specific premises-powered broadband system with an ONT.
