ARTICLE 800 Communications Circuits
800.52 Installation of Communications Wires, Cables, and Equipment.
Communications wires and cables from the protector to the equipment or, where no protector is required, communications wires and cables attached to the outside or inside of the building shall comply with 800.52(A) through (E).
(A) Separation from Other Conductors.
(1) In Raceways, Boxes, and Cables.
(c) Electric Light, Power, Class 1, Non–Power-Limited Fire Alarm, and Medium Power Network-Powered Broadband Communications Circuits in Raceways, Compartments, and Boxes. Communications conductors shall not be placed in any raceway, compartment, outlet box, junction box, or similar fitting with conductors of electric light, power, Class 1, non–power-limited fire alarm or medium power network-powered broadband communications circuits.
Brooke Stauffer of NECA has also written an article on this topic for NFPA called, "You Gotta Keep 'Em Separated". If I can find it on the NFPA website I'll post a link.
