WebThese two curves were used in Equation 1 to calculate the return loss. The results of the simulations, including the Rayleigh scattering, and the analytical results are shown in Figure 4. Figure 4: (a) Simulated gain at 1558 nm. (b) Return loss at 1558 nm versus signal input power. Note: Distance at 10m and 20m for both. WebCoherence length. In physics, coherence length is the propagation distance over which a coherent wave (e.g. an electromagnetic wave) maintains a specified degree of coherence. Wave interference is strong when the paths taken by all of the interfering waves differ by less than the coherence length. A wave with a longer coherence length is closer ...
