    • A core torch for fabricating a single-mode optical fiber preform wherein fine glass particles are produced eccentrically with respect to the center area of a flame stream, the core torch being so arranged as to blow the flame stream at an angle inclined to a seed rod. The porous glass body forming the core is grown on one end of the rod and in the direction of the axis of the rod. A cladding layer is formed on the periphery of the porous glass core body by at least one torch for forming the cladding. The obtained porous glass body is heated and vitrified into a transparent glass body, which is sealed in a silica tube for jacketting to form a single-mode optical fiber preform. At least one exhaust port is disposed within a distance of 1 mm to 50 mm from the periphery of the porous glass body and in the vicinity of the growing surface of the glass body to exhaust residual glass fine particles and undesired gases. A porous glass body having a diameter of 20 mm or less is easily formed. Single-mode optical fiber having a cladding-to-core-diameter ratio of 3 or more is fabricated by the VAD method. Accordingly, a long-length and low-loss single-mode optical fiber is mass-produced.
    • 一种用于制造单模光纤预制件的核心手电筒,其中相对于火焰流的中心区域产生偏心的细玻璃颗粒,所述芯焊炬布置成以与种子杆倾斜的角度吹动火焰流 。 形成芯的多孔玻璃体在棒的一端和棒的轴线方向上生长。 通过用于形成包层的至少一个焊炬在多孔玻璃芯体的周边上形成包覆层。 将得到的多孔玻璃体加热并玻璃化成透明玻璃体,将其密封在用于夹套的石英管中,形成单模光纤预制棒。 至少一个排气口设置在与多孔玻璃体的周边1mm至50mm的距离内,并且在玻璃体的生长表面附近,以排出残余的玻璃微粒和不期望的气体。 容易形成直径为20mm以下的多孔玻璃体。 通过VAD法制造包芯到芯直径比为3以上的单模光纤。 因此,大批量生产长长度和低损耗的单模光纤。
