A device for transmitting digital information (9), in the form of two information-carrying symbols, between two or a plurality of units and in which transmission is by optical means in free medium. The device contains an optical transmitter module (1) with a transmitter unit (5) for transmitting an optical transmission signal (11) and an optical receiver module (2) with a receiver unit (6) for receiving the optical transmission signal (11), and the device is arranged for high speed communications without a carrier wave. The transmitter module (1) is equipped with a formatting unit (3) devised to activate the transmitter unit (5) so this unit emits the transmission signal (11) only during part of a complete symbol interval (16) corresponding to one of the symbols, and the receiver module (2) is equipped with a normalizing unit (8) devised to recreate, from the transmission signal (11) received by the receiver unit (6), both the symbol corresponding to the transmission signal (11) throughout its entire symbol interval (16) and the residual information-carrying symbol in the digital information (9). The invention also relates to a medical implant to which the device for transmitting digital information is applied. <IMAGE> |
