摘要： The invention relates to an interleaver circuit (10, 10′) for interleaving optical signals, comprising a first and a second input port (12, 14), an output port (16), a first optical filter (18; 18′) that has a first filter function with periodic passbands (32, 34, 36) and is connected to the first input port (12), a second optical filter (20; 20′) that has a second filter function with periodic passbands (38, 40) and is connected to the second input port (14), and an optical interleaver (22). The latter comprises a multiplexing port (23) connected to the output port (16) and two de-multiplexing ports (24, 26) connected to the first input port (12) via the first optical filter (18; 18′) and the second optical filter (20; 20′), respectively. At least one optical filter (18, 20; 18′, 20′) is tunable such that the passband frequencies are collectively shiftable without altering the periodicity of the filter function.

摘要： The invention relates to a wavelength division multiplex transmission system; for one channel, the spectral interval between adjacent channels on one side is different from the spectral interval between adjacent channels on the other side. A demultiplexing filter is used which attenuates more strongly the spectrum of the channel on the side on which the spectral interval between adjacent channels is smaller. The invention improves spectral efficiency and retains frequencies chosen from a grid of regularly spaced frequencies.
