Optical transmission line and optical transmission system |
摘要 |
An optical transmission line and an optical transmission system, the handling of which is easy, and in which transmission loss and the absolute value of cumulative chromatic dispersion is small over a wide wavelength range are proposed. The optical transmission system has a transmitter, a receiver and an optical transmission line. The optical transmission line has an optical transmission fiber and a dispersion-compensating fiber. The optical transmission fiber has a chromatic dispersion of +4~+10 ps.nm-1.km-1 and a dispersion slope of 0~+0.04 ps.nm-2.km-1 at the 1550 nm wavelength and is installed in a relay section. The dispersion compensating fiber has a chromatic dispersion of -40 ps.nm-1.km-1 or less and a dispersion slope of -0.10 ps.nm-2.km-1 or less at the 1550 wavelength and is wound in a coil to be put in a repeater.
