摘要： The invention relates to a passive optical network including an optical exchange connected by at least one optical fibre defining a branch of said network to at least one first optical component, said optical exchange including: a means for transmitting/receiving at least one optical data signal; a means for transmitting at least one optical amplification signal; said branch allowing the bi-directional transmission of the optical data signal and of the optical amplification signal. In this network, the branch includes at least one passive amplification device for the optical data signal, said device including: a first passive amplification medium capable of amplifying the optical power of the optical data signal when the latter is transmitted through the branch in a first direction; a second passive amplification medium capable of amplifying the optical power of the optical data signal when the latter is transmitted through the branch in a second direction, the first and second passive amplification media being excited by the optical amplification signal; a means for the selection of optical power gain of the first and second amplification media based on the optical losses respectively associated with the first and second transmission directions of the optical data signal.
