(3) Communications circuits in compliance with Article 800. (4) Community antenna television and radio distribution systems in compliance with Article 820. (c) Grounding. Noncurrent-carrying conductive members of optical fiber cables shall be grounded in accordance with Article 250. 770-53. Applications of Listed Optical Fiber Cables and Raceways. Nonconductive and conductive optical fiber cables shall comply with (a) through (d) below. (a) Plenum. Cables installed in ducts, plenums, and other spaces used for environmental air shall be Type OFNP or OFCP. Also, listed plenum optical fiber raceways shall be permitted to be installed in ducts and plenums as described in Section 300-22(b) and in other space used for environmental air as described in Section 300-22(c). Type OFNP cable shall be permitted to be installed in these raceways. Exception: Types OFNR, OFCR, OFNG, OFN, OFCG, and OFC cables installed in compliance with Section 300-22. (b) Riser. Cables installed in vertical runs and penetrating more than one floor or cables installed in vertical runs in a shaft shall be Types OFNR or OFCR. Floor penetrations requiring Types OFNR or OFCR shall contain only cables suitable for riser or plenum use. Also, listed riser optical fiber raceways shall be permitted to be installed in vertical runs in a shaft or from floor to floor. Types OFNR and OFNP cables shall be permitted to be installed in these raceways. Exception No. 1: Where Types OFNG, OFN, OFCG, and OFC cables are encased in metal raceway or are located in a fireproof shaft having firestops at each floor. ARTICLE 770 - OPTICAL FIBER CABLES AND RACEWAYS 70-787 Exception No. 2: Type OFNG, OFN, OFCG, or OFC cable in one- and I two-family dwellings. (FPN): See Section 300-21 for firestop requirements for floor penetrations. (c) Other Wiring Within Buildings. Cables installed in building locations other than the locations covered in (a) and (b) above shall be Type OFNG, OFN, OFCG, or OFC. (d) Cable Substitutions. The substitutions for optical fiber cables listed in Table 770-53 and illustrated in Figure 770-53 shall be permitted. Table 770-53.
