Fiber optic cable laying to power 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 for a tray. The purpose of this AE Note is to outline the use of fiber optic cables in “tray rated” environments. Many beginners assume that a 100mm x 50mm tray has an area of 5000mm², so they can fit 5000mm². Fiber optic cables have Kevlar aramid yarn or a fiberglass rod as their strength member. You should pull on the fiber cable strength members only! Never exceed the maximum pulling load rating. On long runs, use proper lubricants and make sure they are compatible with the cable jacket. During installation, all curvatures should be smooth. 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.
