How much loss does a 1-to-5 optical splitter have
The equation below can be used to estimate the split ratio and insertion loss for a typical split port. SR=Pi/Pt×100% IL= -10xlog (SR/100)+Гe where IL = splitter insertion loss for the split port, dB Pi = optical output power for single split port, mWExcess 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. 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). A passive optical splitter divides an incoming light signal across two or more output ports.
