The present document relates to an optical multiplexing system (500a) comprising:
- a first multiplexer (510) comprising a first input (511) for receiving a first optical channel set comprising one or more optical channels of an optical channel grid;
- a second multiplexer (520) comprising a first input (521) for receiving a second optical channel set comprising one or more optical channels of the optical channel grid; and
- an optical coupler (530) for transmitting the first and second channel sets via a common optical transmission path (540), the inputs (531) of the optical coupler (530) coupled with the outputs (512, 522) of the first and second multiplexers (510, 520),
wherein
- one channel of the first optical channel set and one channel of the second optical channel set are adjacent channels of the optical channel grid;
- the first multiplexer (510) comprises a first filter unit having a first filter function for filtering the optical signals of one or more optical channels received at the first input (511) of the first multiplexer (510);
- the second multiplexer (520) comprises a second filter unit having a second filter function for filtering the optical signals of one or more optical channels received at the first input (521) of the second multiplexer (520); and
- the bandwidths of the first and second filter functions overlap. |
