Abstract

Dans ce système, la distance a à laquelle il faut prévoir un amplificateur-relais est augmentée par la répartition spectrale des données avant l'émission, par un codeur placé avant l'émetteur optique, et la suppression de cette répartition après la réception, par un décodeur prévu à la suite du récepteur optique.In this system, the distance a at which a relay amplifier must be provided is increased by the spectral distribution of the data before transmission, by an encoder placed before the optical transmitter, and the elimination of this distribution after reception, by a decoder provided following the optical receiver.
