  • Publication number: 20240279104
    Abstract: The present invention relates to a method (200, 400, 500, 600) for drawing a bare optical fiber (118) from a cylindrical glass preform (102) in a furnace chamber (104) by hanging the cylindrical glass preform (102) near a first end (104a) of the furnace chamber (104), injecting first and second inert gasses inside the furnace chamber (104) in a predefined ratio of 0.3 to 5, and melting the cylindrical glass preform (102) while maintaining a positive pressure in the furnace chamber (104) to form the bare optical fiber (118) such that a Bare Fiber Diameter (BFD) variation of the bare optical fiber (118) is less than 0.1 micrometers (?m) from a mean diameter of the bare optical fiber (118).

  • Patent number: 12032203
    Abstract: The present disclosure provides an optical fibre. The optical fibre includes a glass core, a glass cladding, a primary coating layer, and a secondary coating layer. The glass cladding surrounds the glass core. In addition, the primary coating layer sandwiched between the glass cladding and the secondary coating layer. Further, the secondary coating layer surrounds the primary coating layer. The primary coating layer has diameter of up to is in the range of 130 to 155 micrometers. Furthermore, the secondary coating layer has diameter in a range of about 160 micrometers to 180 micrometers. Moreover, diameter of the optical fibre is about 190 micrometers.

  • Publication number: 20230295033
    Abstract: The present invention relates to a flexible sealing assembly (100) for an optical fiber draw furnace (500) comprising a first plurality of curved ring sections (110) arranged in a circular arrangement and a plurality of tension loaders (114) exerting continuous radially inward force on at least one curved ring section. Each curved ring section of the first plurality of curved ring sections (110) is separated from each other and defined by the same radius of curvature. Further, the first plurality of curved ring sections (110) is radially movable such that the first plurality of curved ring sections (110) creates a seal between a glass preform (504) and a vertical hollow body (506) in the optical fiber draw furnace (500). The diameter of the glass preform (504) varies.

  • Patent number: 11719878
    Abstract: An optical fibre includes a glass core, a glass cladding, a primary coating layer and a secondary coating layer. The glass cladding surrounds the glass core. The glass cladding has a cladding refractive index. The primary coating layer is sandwiched between the glass cladding and the secondary coating layer. The primary coating layer may have one of a primary in-situ modulus in the range of 0.1 to 0.2 mega pascal and a primary coating thickness in the range of 2.5 micrometers to 10 micrometers. The secondary coating layer may have one or more of the secondary in-situ modulus greater than or equal to 1.2 giga pascal and the secondary coating thickness in a range of 2.5 to 17.5 micrometers.
