Fill Ratio Calculation Worksheet
This worksheet will allow you to calculate the fill ratio using one, two, or three cables within the conduit. If you only have one cable for your conduit, please use only the first cable diameter field.
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.
