Fiber optic cables cannot be routed through cable trays
While there are several specific types of listings for power cables, specifically for tray applications, there is no equivalent tray rating for optical fiber cables. According to the 2014 National Electric Code® (NEC), any listed optical fiber cable is acceptable. The purpose of this AE Note is to outline the use of fiber optic cables in “tray rated” environments. NEC section 300-8 does not permit any tube, pipe, or equal for water, air gas, drainage, steam, or any service other than electrical in raceways or cable trays containing. Conductive optical fiber cables aren't permitted to occupy a cable tray or raceway with electric light, power or Class 1 circuits [770. Recommendations for Fiber Optic Cable Installation Where reels are supplied with protective material fitted over the cable, the protection should remain in place until the cable will be installed. During installation, all curvatures should be smooth. Outdoor cable may be direct buried, pulled or blown into conduit or innerduct, or installed aerially between poles.
