Article 800 will also include listing requirements for communications circuit integrity (CI) cables, as well as communications cables used in Fire-Resistive Cable systems and Electric requirements in Article 800. You select between them based on route exposure, rodent risks, burial requirements, tension loads, and overall ODN architecture.
