Optical field propagating an optical fiber can be expressed as along E(z, t) = E_0 exp[- j(omega t – beta z)] middot exp (-alpha)z, where alpha = 1.15 times 10^-4 m^-1. What is the power attenuation parameter in dB/km? If the fiber length is 30km and the input optical power is 10dBm, what is the optical power at the fiber output?
