This outline states basic construction, test, and marking requirements for the safety of electrical and electrical/optical fiber cables that are for use in network-powered broadband communications systems as specified in Article 830 and other applicable parts of the National Electrical Code (NEC), ANSl/NFPA 70-2002. These cables (\"broadband cables\") are for use as fixed wiring within and between buildings and are also for service and drop use entering buildings and terminating at network interface units, which convert the broadband signal to its component voice, video, data, and interactive-service signals for distribution by the cables referenced in 1.17(a) - 1.17(e). Broadband cables are insulated for 300 volts (no marking) and are of the specific types and voltage ratings described in (a) - (0. The use hierarchy of these cables is described in (g).a) PLENUM CABLES - Type BLP (electrical) and Type BLP-OF (electrical/optical fiber). These types are for 0 - 100 volt Iow-power circuits. These types are for installation in buildings whereexposed in ducts, plenums, and other spaces used to transport environmental air [NEC 830.55(B)] and where exposed in vertical runs in a shaft or in vertical runs that penetrate more than one floor [NEC 830.55(C)(1)]. These types are also for other wiring installed exposed in buildings [NEC 830.55(D)]. These types are rated and marked \"100 volts\" or \"100 V\". b) RISER CABLES - Type BMR (electrical) and Type BMR-OF (electrical/optical fiber). Thesetypes are for 0 150 volt medium-power circuits. These types are for installation in buildingswhere exposed in vertical runs in a shaft or in vertical runs that penetrate more than one floor[NEC 830.54(B) and 830.55(C)(1)]. These types are also for exposed use outside and enteringbuildings [NEC 830.10(A)]. These types are rated and marked \"150 volts\" or \"150 V\". c) GENERAL-PURPOSE CABLES - Type BM (electrical) and Type BM-OF (electrical/optical fiber). These types are for 0 - 150 volt medium-power circuits. These types are for general use exposed in buildings [NEC 830.54(C) and 830.55(D)(1)], which does not include exposed use in risers (unless the shaft is fireproof with firestops at each floor) and does not include exposed use in plenums. These types are also for exposed use outside and entering buildings [NEC 830.10(A)]. These types are not for direct burial. These types are rated and marked \"150 volts\" or \"150 V\". d) OUTDOOR UNDERGROUND CABLES FOR MEDIUM-POWER CIRCUITS - Type BMU (electrical) and Type BMU-OF (electrical/optical fiber). These types are for 0 - 150 volt medium-power circuits. These types are for entering buildings in conduit [NEC 830.54(C), Exception]from direct burial [NEC 830.5(A)(1)]. These types are rated and marked \"150 volts\" or \"150 V\".
