Effective Interaction Length Solution

STEP 0: Pre-Calculation Summary

Formula Used

Effective Interaction Length = (1-exp(-(Attenuation Loss*Length of Fiber)))/Attenuation Loss
L_eff = (1-exp(-(α*L)))/α
This formula uses 1 Functions, 3 Variables

Functions Used

exp - n an exponential function, the value of the function changes by a constant factor for every unit change in the independent variable., exp(Number)

Variables Used

Effective Interaction Length - (Measured in Meter) - Effective Interaction Length used to describe the distance over which light can interact with or propagate through the fiber before certain optical effects become significant.
Attenuation Loss - Attenuation loss in fiber optics refers to the reduction in the strength or intensity of an optical signal as it propagates through an optical fiber.
Length of Fiber - (Measured in Meter) - Length of Fiber is defined as the total length of fiber cable.
