Optical demultiplexing system for wavelength bands |
| 摘要 |
<p>The optical demultiplexing wavelength band separation has a front filtering stage (210) of low pass band and high selectivity extracting an assembly of inter band channels. A second stage of filtering (240) has a high pass band and low selectivity extracting the wavelength bands delivered by the first filtering stage.</p> |
