Optical fiber line, optical transmission line, method of making optical cable, and method of laying optical transmission line |
摘要 |
The present invention relates to an optical fiber line for transmitting a plurality of wavelengths of optical signals in a wavelength division multiplexing transmission system, an optical transmission line, a method of making an optical cable, and a method of laying an optical transmission line. The optical fiber line in accordance with the present invention comprises a plurality of positive dispersion optical fibers, having a positive chromatic dispersion in a signal wavelength band, selected from a positive dispersion optical fiber group whose cumulative dispersion conforms to a distribution with an average value of DA (>0) and a standard deviation of sigmaA; and a plurality of negative dispersion optical fibers, having a negative chromatic dispersion in the signal wavelength band, selected from a negative dispersion optical fiber group whose cumulative dispersion conforms to a distribution with an average value of DB (<0) and a standard deviation of sigmaB; the positive and negative dispersion optical fibers being alternately arranged and coupled in a longitudinal direction. This optical fiber line has a high transmission quality and can be constructed inexpensively.
