Abstract

The present invention refers to an optical multiplexing device (10, 10', 10a, 10b) destined to be coupled to an optical transmission line (14) for transmitting a multiplexed signal comprising a plurality of multiplexed wavelength channels within a given waveband, the said optical multiplexing device comprising: - a first wavelength selective switch "WSS" (12, 26) comprising a plurality of input/output ports (121, 123, 125, 127, 261, 263, 265, 267), - a first optical amplifier (18) having an output configured to be coupled to an input/output port (125, 265) of the first wavelength selective switch (12) and configured for emitting amplified spontaneous emission signals on the given waveband, wherein the first wavelength selective switch (12) is configured for transmitting the amplified spontaneous emission signals on the idle wavelength channels of the multiplexed signal, - a second wavelength selective switch (22, 26), - a second optical amplifier (20) having: - an input configured to be coupled to an input/output port (127, 267) of the first wavelength selective switch (12, 26) and - an output configured to be coupled to an input/output port (225, 269) of the second wavelength selective switch (22, 26), the first wavelength selective switch (12, 26) being configured for transmitting the spontaneous emission signals received from the first optical amplifier (18) toward the second optical amplifier (20) and the second wavelength selective switch (22, 26) being configured for transmitting the amplified spontaneous emission signals received from the second optical amplifier (20) toward the optical transmission line (14).
