摘要： In the fiber-drawing method, a first preform is lowered along a fiber-drawing axis through a fiber-drawing oven so as to be heated and drawn down into an optical fiber, and a second preform is lowered along the fiber-drawing axis through the fiber-drawing oven so as to be heated and drawn down in turn after the first preform has been withdrawn. While the first preform is being drawn down into a fiber, the second preform is heated in a preheating oven disposed adjacent to the fiber-drawing oven so as to raise the second preform to a temperature which is slightly below the fiber-drawing temperature, and the preheated second preform is transferred quickly onto the fiber-drawing axis after the first preform has been withdrawn therefrom. This method contributes to increasing the capacity for producing optical fibers.
摘要翻译：在纤维拉伸法中，第一预成型体沿着拉丝轴线通过纤维拉伸炉降低，以被加热并拉伸成光纤，并且第二预成型体沿着拉丝轴线通过该纤维拉伸炉在第一预型件已经被取出之后依次被加热和拉下。当第一预成型件被拉伸成纤维时，第二预型件在与拉丝炉邻近设置的预热炉中加热，以将第二预制件升高到略低于拉丝温度的温度，以及在第一预制件从其中取出之后，将预热的第二预型件快速地转移到拉丝轴上。该方法有助于增加制造光纤的能力。

摘要： The invention relates to a method of assembling two optical fiber preforms together end-to-end, the method comprising the following operations: the two cylindrical preforms are placed in alignment along a common longitudinal axis; the preforms are rotated about the common longitudinal axis; the facing ends of said preforms are heated by a heater; and the preforms are moved towards each other parallel to the common axis to press them against each other so as to form intimate contact between the ends after cooling. According to the invention, the heating is performed by causing the preforms or heater to move in a radial direction orthogonal to the common longitudinal axis in such a manner as to heat the peripheries and then the cores of said preforms.
摘要翻译：本发明涉及一种将两个光纤预制件端对端组装的方法，该方法包括以下操作：将两个圆柱形预成型件沿着共同的纵向轴线对齐;预制件围绕公共纵向轴线旋转; 所述预制件的面对端由加热器加热; 并且预成型件彼此平行于公共轴线彼此移动，以将它们彼此压紧，以便在冷却之后在端部之间形成紧密接触。根据本发明，通过使预成型件或加热器沿与公共纵向轴线正交的径向移动，从而加热周边，然后加热所述预成型件的芯，来进行加热。
