We evaluate the advantage of using space–time coding in order to increase the tolerance of fiber-optic communications systems to polarization-dependent loss (PDL). Focusing on three particular codes, the Golden Code, the Silver Code (SC), and the Alamouti Code (AC), we calculate the amount of average PDL that can be tolerated for a given signal-to-noise ratio margin that is designed into the system. The SC is shown to be optimal in the case of low to moderate PDL, whereas, in the case of extreme PDL, the AC shows the best performance.

  17. We note that since the time constants characterizing the temporal variations of the channel matrix are typically much longer than the FEC frame, other commonly used quantities such as the ergodic capacity are of no relevance in our case.
