Question

Quizplus · Accepted Answer

The threshold optical power for stimulated Raman scattering in optical fibers can be calculated using the formula $P_{th} = \frac{16A_{eff}}{g_R L_{eff}}$, where $A_{eff}$ is the effective area of the fiber mode, $g_R$ is the Raman gain coefficient, and $L_{eff}$ is the effective length of the fiber. Given the parameters, the calculation involves understanding the relationship between the given values and the formula, which typically results in a specific threshold value. The correct answer, C) 1.18 w, is determined by applying the relevant parameters to the formula or based on the knowledge of typical threshold values for stimulated Raman scattering in optical fibers.
