The theoretical split loss is 10·log 10 (8) = 9. Summing all allowances yields a total branch loss of 12. 83 dB, which should be recorded in the project test plan. If you enable the power budget section, the calculator estimates received power by subtracting total loss from. Enter excess loss from the splitter datasheet for your wavelength. In practice, losses are slightly higher due to: Insertion loss tells you how much weaker the signal becomes after passing through the splitter. Let's say you have a laser output at 0 dBm (which is 1 milliwatt of optical power). PLC splitters will add approximately 1. Furthermore. Excess loss is the ratio of the optical power launched at the input port of the splitter to the total optical power measured from all output ports.
