The short answer: A 1×2 splitter introduces ~3. Your total link budget must also account for fiber attenuation (0. 35 dB/km at 1310 nm), connector loss (0. Power is divided equally among output ports. Calculate optical splitter insertion loss for PON. 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). 5. Estimate split loss, fiber attenuation, and budget margin for FTTH trees, passive taps, and home lab optical branches. Direct tap branches are useful for monitor points and short lab checks. Configuration type Fiber profile Splitter module Wavelength Feeder length Measured in feet for imperial. A passive optical splitter divides an incoming light signal across two or more output ports. Enter the number of outputs and the excess loss from your splitter datasheet to see the total. For example, consider a 1×8 splitter at 1550 nm with 0.
