| 摘要 |
An optical transmitting device suitable for use in a wavelength division multiplexing optical transmission system for transmitting a plurality of optical signals different in wavelength through a transmission line. The optical transmitting device includes a plurality of electro-optical converters for respectively converting electrical signals into a plurality of optical signals different in wavelength, a plurality of pre-compensators for chromatic dispersion respectively connected to the plural electro-optical converters, for respectively giving certain chromatic dispersions to the plural optical signals, and an optical multiplexer connected to the plural pre-compensators for chromatic dispersion, for multiplexing the plural optical signals to which the certain chromatic dispersions have been given. Each pre-compensator for chromatic dispersion compensates for a chromatic dispersion difference in the transmission line due to a wavelength difference between a wavelength of each optical signal and a specific wavelength at which a chromatic dispersion in the transmission line becomes zero. |
