How to calculate the quota for two optical cables

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 the number of copper or fiber cables required to serve the user-entered number. Enter your fiber type, distance, connectors, splices, and components to calculate total optical loss, link margin, and power budget with engineering-grade accuracy. Add each MUX or DEMUX on the path. Choose a preset for typical insertion loss, or enter a custom value. Fiber optic loss, or simply loss in fibers, measures how much light disappears between the entry and the exit. The same inputs also estimate optical power budget, received dBm, receiver overload risk, and maximum supported reach. Results are estimates for preliminary design.
