Transmission system for polarization-independent transmission of signals via a signal trajectory between a first and a second transceiver, each of which comprise a transmitter T and a receiver R. The receiver comprises a detector D, a local oscillator LO and an arrangement for injecting the output signal of the oscillator into the detector. A high-order retarder HR is connected, on one side, to the signal trajectory ST and on the other side to a port of a hybrid circuit H. Connected to the other ports of the hybrid circuit H are a transmitter T and a receiver R, respectively.
