Abstract :
Polarization characteristics in environmental disturbance are evaluated, in terms of the signal-to-noise ratio (SNR), which is defined as the ratio of a mean to a standard deviation of time-varying signals. The SNR is computer-simulated, assuming a Gaussian probability distribution for the random variables, i.e. birefringent axis, linear retardance, and polarization mode-coupling. These parameters are assumed to fluctuate owing to the force vibration of a loudspeaker. A comparison of the numerical results with the experimental SNR provides a direct connection between fluctuations of the state of polarization (SOP) and SNR of received signals modulated by polarization noise in highly birefringent fiber systems
