Proportion of optical fiber cable occupying the cable tray
Size the tray by calculating total cable cross-sectional area and dividing by the allowable fill percentage (typically 40%). Add 20–30% spare capacity for future cables. Standard tray widths are 6, 9, 12, 18, 24, and 30 inches. The purpose of this AE Note is to outline the use of fiber optic cables in “tray rated” environments. The Fire Marshal arrives and fails the inspection because you exceeded the 40% Fill Ratio. Use our **Cable Tray Fill Calculator** below to size your pathways correctly. 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. Turn-backs and all sharp changes of direction. maintain spacing or to keep cables in place when the tray is ect the minimum bend ra-dius for cables as they exit the bottom of the cable tray.
