"Low Voltage" is not defined by the National Electrical Code and strictly speaking, optical fiber cable systems which transmit information using high-speed bursts of light generated by tiny lasers, are "no-voltage". Various terms for describing the different technologies are describing these diverse systems.
Articles covering low-voltage and power-limited devices, wiring, and systems are generally contained in Chapters 7 and 8 of the National Electrical Code. However, Chapters 4 and 5 of the NEC contains the requirements for:
Low-Voltage Lighting (Article 411)
Intrinsically Safe Systems (Article 504)
Sound Systems (Article 640)
