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. log10 is the base-10 logarithm. Theoretical Loss = 10 * log10 (2) ≈ 10 * 0. 301 =. For example, for the loss (attenuation) in a segment of optical fiber we have the value at the input of the segment and at its output. in Watts – W), the loss value in dB is calculated by the formula: Loss (dB) = 10 lg ( mW1 / mW2 ) When both gains. This calculator separates splitter loss, fiber attenuation, and receiver margin so you can see the real budget impact before you build. These are known as passive optical splitters, and they perform the function. Optical splitter, including FBT (Fused Biconical Taper) couplers and PLC (Planar Lightwave Circuit) splitters, are common passive optical devices that split the fiber optic light into several parts by a certain ratio.
