Home / Fiber optic cable tray cross-section fill rate
The NEC rule requires that the cable cross-sectional areas together may not exceed 50% of the tray area (width x depth = fill). 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. This calculator determines if your tray meets industry standards (typically 30-50% fill for alternating single-layer or 40-50% for random arrangement). Fill ratio — IEC 61537 and NEC Article 392 both cap power cables at 40–50 % of the tray cross-section. Metosu's TRC (perforated) and TRU (non-perforated) trays ship in 10 widths (100–900 mm), 4 depths (50–150 mm), and 2 standard.
This calculator is designed to estimate fill ratio for fiber optic cables installed in ducts. Fill ratio is one of many variables that must be considered when planning fiber optic cable installations. Corning Optical
