The formula for the theoretical loss for each output port of a splitter with N output ports is: Theoretical Split Loss (in dB) = 10 * log10 (N) Where: N is the number of output ports the splitter has (e., 2 for a 1x2 splitter, 4 for a 1x4, 8 for a 1x8, 32 for a 1x32, etc. Calculate split loss, excess loss, and terminations for any ratio quickly today. See power budget impact instantly, then download a CSV or PDF summary. Use 2×N when two inputs feed the same distribution stage. Common values: 2, 4, 8, 16, 32, 64.

Let's say you have a laser output at 0 dBm (which is 1 milliwatt of optical power).
