| 摘要 |
<p>The invention relates to an optical soliton transmission system and a process for transmitting optical soliton pulse signals in such a system at a predetermined transmission speed. The system comprises at least one source (1, 2, 3, 4; 28a-28d; 29) of optical soliton pulse signals having a wavelength in a predetermined transmission wavelength band and an optical fibre line (9, 42a-e) into which said signals are launched. The optical-fibre line (9, 42a-e) comprises an optical fibre (9, 42a-e) having a chromatic dispersion increasing with the wavelength wherein said chromatic dispersion exhibits a nominal zero value at a wavelength of greater than 1500 nm and smaller than 1600 nm and lower than the minimum wavelength of said transmission band by such an amount that no local zero value of chromatic dispersion, present in the optical fibre and capable of generating a spectral modification of said optical soliton pulse signals, is included in said transmission band. <IMAGE></p> |
