Plastic optical fiber for weaving

[0028] Example one

[0029] In this embodiment, the overall diameter of the optical fiber is 0.25 mm, that is, the outer diameter of the cladding 1 is 0.25 mm. For the selection of optical fiber materials, this embodiment selects A1 type polymethyl methacrylate with a tensile strength of 66 MPa as the core material, and the outer diameter of the core layer is 0.23 mm, and selects B1 type with a tensile strength of 355 MPa The fluororesin as the cladding material has a light transmittance of 92%. The loss of the plastic optical fiber produced by such a combination is 0.3dB / m~0.5dB / m. When processing this kind of optical fiber, the temperature of the core extruder and cladding extruder is controlled at 220℃~240℃, and then the core material is melted and plasticized by the core extruder and extruded into it. The die is formed into a core, and the cladding material is melted and plasticized by the cladding extruder and extruded into the die, so that the cladding material is wrappe

[0030] Example two

[0031] In this embodiment, the overall diameter of the optical fiber is 0.5 mm, that is, the outer diameter of the cladding 1 is 0.5 mm. For the selection of optical fiber materials, the selected optical fiber material combination in this embodiment is the same as that in Embodiment 1, and the outer diameter of the core layer is 0.23 mm, and the loss of the optical fiber is also 0.3dB / m-0.5dB / m. When processing the optical fiber, the temperature of the core extruder and the cladding extruder is controlled at 200℃~220℃, and then the core material is melted and plasticized by the core extruder and extruded into the die. For the core, the cladding material is melted and plasticized by the cladding extruder and extruded into the mold so that the cladding material is wrapped around the core. Finally, the core extruder and the cladding extruder work simultaneously to extrude the material from the mold After drawing and winding into a coil, the mold specification

[0033] In this embodiment, the overall diameter of the optical fiber is 0.25 mm, that is, the outer diameter of the cladding 1 is 0.25 mm. For the selection of optical fiber materials, this embodiment selects A2 model polymethyl methacrylate with a tensile strength of 78 MPa as the core material, and the outer diameter of the core layer is 0.23 mm, and selects B2 model with a tensile strength of 480 MPa The fluororesin as the cladding material has a light transmittance of 90%. The loss of the plastic optical fiber produced by such a combination is 1.0dB / m~2.0dB / m. When processing this optical fiber, the temperature of the core extruder and cladding extruder is controlled at 220℃~240℃, and then the core material is melted and plasticized by the core extruder and extruded into it. The die is formed into a core, and the cladding material is melted and plasticized by the cladding extruder and extruded into the die, so that the cladding material is wrapped ar
