The transmission system uses an optical signal phase modulated in dependence on the information to be transmitted at the transmission side, supplied to an optical fibre transmission path. An amplitude modulation is provided along the transmission path due to its group velocity dispersion, with the amplitude modulation of the transmission signal detected at the reception end. Pref. the transmission path is provided by a standard single-mode optical fibre, exhibiting a dispersion of 17 ps/(nm km), with the amplitude modulation detected directly at the reception end. |
