Estimate optical attenuation, received power, design margin, and maximum supported reach for a fiber path. Use common planning presets or enter exact vendor values for attenuation, connector loss, splice loss, passive component loss, transmitter minimum output, and receiver sensitivity. Planning. To ensure that fiber-optic connections have sufficient power for correct operation, calculate the link's power budget when planning fiber-optic cable layout and distances. First, you should be aware of the fiber loss formula: The Total Link Loss = Cable Attenuation + Connector Loss + Splice Loss Cable Attenuation (dB) = Maximum Cable Attenuation. This calculator allows you to plug in values for all variables that will impact your systems' performance.
