Optical fiber transmission-line |
摘要 |
A dispersion-managed optical fiber transmission-line with which the formation of side bands around the optical signal wavelength can be suppressed even when carrying out high-speed signal transmission. An optical fiber transmission-line 1 constitutes one repeater span installed between a transmitter (or repeater) 2 and a receiver (or repeater) 3 and is made up of N sections 41 through 4N in sequence from the transmitter 2 to the receiver 3. The chromatic dispersion at the wavelength 1.55 mum is positive in the sections 4n where the value of n is odd and is negative in the sections 4n where the value of n is even. The ratio between the maximum value and the minimum value of the average chromatic dispersions Dn of the sections 4n is at least 1.3 and not greater than 10.0.
