Method for transmitting laser signals (L), wherein an electric signal (S) containing information to be transmitted is received by an input interface (IN) and sent to a laser emitter (LE) which emits a laser signal (L) containing said information, wherein before reaching the laser emitter (LE) said electric signal (S) or one or more electric signals (I, Q) corresponding thereto modulate one or more carrier signals at intermediate frequencies comprised between the frequencies of the laser signal (L) and the electric signal (S) received by the input interface (IN). The present invention also relates to a method for receiving the laser signals so transmitted, as well as a transmitter and a receiver which carry out said methods. |
