  • How to calculate the core reel of a communication optical cable

    How to calculate the core reel of a communication optical cable

    With our easy cable reel capacity calculator, you can calculate the maximum reel, spool or drum capacity. Compute the ratio between the diameter of your chosen cable and the diameter of the conduit you plan to use. Calculate the amount of remaining space available for use in the cable tray once. For a good estimate, you need to have four numbers: the diameter of the core of the reel (the hub), the outer diameter of the rolled-up tape, the thickness of the carrier tape and the distance that the components are spaced from each other on the tape. You can use it when you need fast reference values during design or checking stages. Cable reels are widely used in industries such as telecommunications, electric power generation and oil and gas.
