Abstract

The invention belongs to the technical field of optical fiber and cable, and discloses an optical fiber heat treatment method and device, including a temperature controller, an optical fiber clamping device and a tube furnace, wherein the optical fiber clamping device is used to clamp the optical fiber, and the optical fiber passes through In the tube furnace, the temperature controller is used to set the fiber heat treatment temperature conditions of the tube furnace, release the internal residual stress of the fiber and introduce material thermal stress through the heat treatment process. Using the heat treatment device of the present invention to heat-treat the optical fiber can effectively release the residual stress inside the optical fiber, and introduce the thermal stress of the gradient material through slow cooling conditions, and obtain the thermal stress result of the optical fiber through the conventional optical fiber stress testing method.

Description

technical field [0001] The invention belongs to the technical field of optical fiber and cable, and more specifically relates to a method and device for heat treatment of optical fiber. The device for heat treatment of optical fiber is used to test the thermal stress of silica glass optical fiber, and it is a manufacturing technology for in-depth research on the performance mechanism and optimization process of silica optical fiber. support. Background technique [0002] Attenuation and stress sensitivity are the key characteristics of optical fiber. The attenuation of the optical fiber working window wavelength between 600nm and 1600nm mainly comes from Rayleigh scattering. When light energy is incident on an inhomogeneous medium, the medium will produce isotropic scattered light due to the inhomogeneous refractive index, that is, Rayleigh scattering. [0003] During the fiber drawing process, due to the rapid cooling of the glass material and the influence of mechanical t...
