摘要： Methods for preform and tube draw based on controlling forming zone viscosity determined by calculating a holding force exerted by the glass component in the forming zone on the strand being drawn below. The holding force may be calculated by determining a gravitational force applied to the strand and a pulling force applied to the strand by a pulling device, where the holding force is equal to the opposite of the algebraic sum of the gravitational and pulling forces. The holding force may also be calculated by measuring a stress-induced birefringence in the strand at a point between the forming zone and the pulling device, determining an amount of force applied to the strand at the point corresponding to the birefringence, and calculating the holding force by correcting the amount of force for a gravitational effect of the weight of the strand between the forming zone and the point.

摘要： Prior to fabrication of an optical fiber with desired optical properties, a preform geometry is determined dependent upon a fiber geometry that possesses the desired optical properties. The desired geometry may contain a large number of channels. The processor determines the preform geometry by tracking backwards in time the parameters of a set of conformal mappings that describe the cross section of the fiber. Some of the drawing process parameters may be specified, while other parameters may be determined along with the preform geometry. The determined preform geometry may be used to fabricate the required preform. Using this preform, the determined drawing process parameters may be used to draw the desired fiber.

摘要： When a GRIN lens fiber is drawn from a preform, control of a fiber diameter is improved in order to increase a production yield of the GRIN lens fiber having a fiber diameter within a desired range. The problem is solved by controlling the drawing speed using a fiber diameter c, which is obtained by correcting a fiber diameter a using the fiber diameter b and a fiber diameter α. The fiber diameter a is measured using a diameter measuring instrument A that measures an outer diameter of the GRIN lens fiber, which is being elongated inside a heating furnace, the fiber diameter b is measured using a diameter measuring instrument B that measures an outer diameter of the GRIN lens fiber outside the heating furnace, and the fiber diameter α is a value of the fiber diameter a measured a specified period of time T earlier.

摘要： Methods for modifying preform core ovality during and subsequent to the formation of an optical fiber preform. After MCVD deposition forms the core rod, but prior to overcladding of the core rod, the code rod may be etched to change its ovality. In order to etch the core rod, the core rod may be mounted to lathe, rotated by at least two rotors, and subjected to a heat source. Additionally, one of the at least two rotors may be phase-shifted from another one of the at least two rotors after the core rod is mounted on the lathe.
