    • An apparatus for compensating for dispersion of an optical fiber in an optical line, which compensates for dispersion generated in the optical fiber when an optical signal produced by an optical transmitter is transmitted to an optical receiver via the optical line, is provided. The apparatus includes a dispersion compensation fiber for compensating an optical signal produced by an optical transmitter in order to predict and compensate for dispersion generated in the optical line, a dispersion compensation filter for controlling the dispersion value of the optical signal dispersion-compensated by the dispersion compensation fiber, to gain zero overall dispersion, and an optical amplifier for amplifying a signal having a dispersion value adjusted by the dispersion compensation filter and outputting the result to the optical line. Accordingly, it is easy to zero a dispersion value of an optical fiber in the optical line by regulation of the dispersion compensation fiber and filter. When the dispersion value varies with the deterioration of the optical fiber in the optical line, continuous compensation is not possible using only the dispersion compensation fiber. However, continuous compensation is easily made by adding the dispersion compensation filter.
    • 提供了一种用于补偿光纤中的光纤在光线路中的色散的装置,其补偿当由光发射机产生的光信号经由光线路产生的光信号时在光纤中产生的色散。 该装置包括:色散补偿光纤,用于补偿由光发射机产生的光信号,以便预测和补偿在光线路中产生的色散;色散补偿滤波器,用于控制由色散补偿的光信号的色散值 补偿光纤,以获得零总体色散;以及光放大器,用于放大具有由色散补偿滤波器调整的色散值的信号,并将结果输出到光线路。 因此,通过色散补偿光纤和滤波器的调节,很容易使光纤中的光纤的色散值归零。 当色散值随着光学线路中的光纤的劣化而变化时,仅使用色散补偿光纤不能进行连续补偿。 然而,通过添加色散补偿滤波器可以容易地进行连续补偿。

    • An optical fiber having a multi-step core structure, and a method of fabricating the same, are provided. The optical fiber includes a central core having a predetermined radius a1 from an central axis and a refractive index n1, a first outer core having a radius a2 and a refractive index n2 smaller than the refractive index n1 and surrounding the central core, a second outer core having a radius a3 and a refractive index n3 smaller than the refractive index n2 and surrounding the first outer core, and a cladding having a radius a4 and a refractive index n0 smaller than the refractive index n3 and surrounding the second outer core, i.e., a1 n2>n3>n0. The diameter of the core is increased by making the refractive index distribution of the core multi-stepped, thus providing easy fabrication. The optical fiber has a low dispersion value in a 1550 nm wavelength, thus making superspeed long distance transmission possible.
    • 提供具有多级芯结构的光纤及其制造方法。 光纤包括具有中心轴的预定半径a1和折射率n1的中心纤芯,第一外芯具有半径a2,折射率n2小于折射率n1并围绕中心芯,第二外芯 芯部具有半径a3,折射率n3小于折射率n2并围绕第一外芯,以及包层,其具有半径a4,折射率n0小于折射率n3并围绕第二外芯,即, a1 n2> n3> n0。 芯的直径通过使芯的折射率分布多级增加,从而提供容易的制造。 光纤在1550nm波长处具有低色散值,从而使得超高距离传输成为可能。

    • A gas generator includes a lower shell, an upper shell, a holding portion, an igniter, and a filter. The lower shell is made of a press-formed product formed by press-working one plate-shaped member made of metal, and includes a protruding cylindrical portion and an opening provided in the protruding cylindrical portion. The holding portion is formed from a resin-molded portion formed by attaching an insulating fluid resin material to a bottom plate portion so as to reach a part of an outer surface from a part of an inner surface of the bottom plate portion of the lower shell through the opening and solidifying the same, and includes an accommodation recess portion in a portion opposed to a top plate portion. The igniter is held by the holding portion while it is inserted in the accommodation recess portion from a side of the top plate portion and fitted therein.
