Polarization multiplex signals optical transmission method for wave division multiplex system, involves forming polarization-multiplex signals from two optical data signals with phase shift of ninety degree in its carrier signals

摘要

The method involves forming polarization-multiplex signals (PMS1, PMS2) from two modulated optical data signals (PS1x, PS1y, PS2x, PS2y) with a phase shift of 90 degree in its carrier signals (TS1z, TX1y, TX2x, TX2y). The polarization multiplex signals are circularly polarized in opposite directions. The data signals (PS2x, PS2y) are transmitted with polarizations rotated around 45 degrees from the data signals (PS1x, PS1y).
