How to calculate optical cable specifications
All lengths are calculated in a base unit, then converted. Reel count is ceil (Total ÷ ReelSize), and the rounded order length equals Reels × ReelSize. Choose your unit and keep it consistent. Fiber optic cables can be custom cut by Proterial Cable America or distributor to match your required lengths for each cable run. We advise you to incorporate a safety buffer when ordering. Use this worksheet to input values for all variables that will impact your system's performance. Sometimes the power budget has both a minimum and maximum value, which means it needs at least a minimum value of loss so that it does not. Using this simple mathematical formula allows you to determine your link budget early in the project so you can determine the appropriate safe operating range and save yourself from unnecessary expenditures on rewiring, splices, or excess reels of fiber optic cable. Connector loss is always measured as a mated pair.
