摘要： In the dispersion-compensating system of the present invention, a demultiplexer demultiplexes optical signals in a signal wavelength band of 1520 nm to 1620 nm propagating through a first common transmission line into C band (1520 nm to 1565 nm) and L band (1565 nm to 1620 nm). Then, the demultiplexer outputs the optical signals of C band into a first branched transmission line and the optical signals of L band into a second branched transmission line. A first dispersion-compensating device is provided on the first common transmission line and compensates for the dispersion in C and L bands. A second dispersion-compensating device is provided on the second branched transmission line and compensates for the dispersion in L band, which has not fully been compensated for by the first dispersion-compensating device. Hence, the dispersion of optical transmission line can fully be reduced in a wide signal light wavelength band.

摘要： The present invention relates to an optical transmission line suitably used for a large-capacity high-speed WDM optical transmission system, and an optical fiber suitably used for such an optical transmission line. The optical transmission line is formed by connecting a single-mode optical fiber (SMF) and a dispersion compensating optical fiber (DCF). The dispersion compensating optical fiber has a dispersion value DDCF (unit: ps/nm/km) and dispersion slope SDCF (unit: ps/nm /km) falling within the ranges of -82

摘要： The present invention relates to an optical transmission line enabling WDM communications in a wide signal light wavelength band centered at a wavelength of 1.55 mu m, in which nonlinear optical phenomena are less likely to occur; and an optical fiber constituting a part of the optical transmission line. The optical fiber has a dispersion D (unit: ps/nm/km) and a dispersion slope S (unit: ps/nm /km) satisfying the conditions of -83 or more and a bending loss of 50 dB/m or less when wound at a diameter of 20 mm.

摘要： An optical transmission line (5) includes a portion where a first optical fiber (1) and a second optical fiber (2) having different structures are fused and connected. The first optical fiber (1) has a mode field diameter smaller than that of the second optical fiber (2). The average viscosity of the first optical fiber (1) from the center to the outermost layer is higher than that of the second optical fiber (2). Low-viscosity core region (11) and first cladding region (12) of the first optical fiber (1) are sheathed by a high-viscosity second cladding region (13) and are closed at their end faces by a high-viscosity core region (21) of the second optical fiber (2). As a result, the two core regions (11 and 21) can be suppressed in their deformations to reduce the connection loss at the fused and connected portions.

摘要： A demultiplexer in a dispersion compensation system of the invention separates an optical signal in a 1520-1620 nm band propagating through a first common transmission path into two bands, i.e., C band (1520-1565 nm) and L band (1565-162O nm). The demultiplexer then sends the optical signal in the C band and the optical signal in the L band to a first branch path and a second branch path, respectively. A first dispersion compensation device is provided in the first common transmission path to compensate for dispersion in the C and L bands. A second dispersion compensation device is provided in the second branch path to compensate for dispersion in the L band if the dispersion compensation by the first dispersion compensation device is insufficient. It is thus possible to sufficiently compensate for the dispersion of an optical transmission path in a wide signal band.
