Joint probability density function of estimation errors of DGD and power split factor, the parameters defining the first order Polarization Mode Dispersion in an optical fibre, is formulated and used as a tool for investigation of influence of uncertainty of the reference signal, required by PMD measurement method, on uncertainty of the estimates. With the application of confidence intervals the uncertainty...
Five parameters that describe a static characteristics of a non-zero chirp Mach-Zehnder intensity modulator and a method for their estimation from intensity samples are proposed. The practical value of the parameters and of the method of their estimation is examined in laboratory experiments.
