Abstract
Official abstract text for this publication.
An optical fiber includes a glass fiber and a coating resin layer with which the glass fiber is covered, wherein the coating resin layer includes tin and a cured ultraviolet curable resin composition containing 2,4,6-trimethylbenzoyldiphenyl phosphine as a photoinitiator, a percentage of uncured components having a molecular weight of 1000 or less included in the coating resin layer is 15% by mass or less, and a fraction of an amount of a phosphorus-tin complex with respect to an amount of hydrocarbon on the surface of coating resin layer is 1000 ppm or less.
First claim
Opening claim text (preview).
The invention claimed is: 1. An optical fiber comprising: a glass fiber and a coating resin layer with which the glass fiber is covered, wherein the coating resin layer has a primary resin layer and a secondary resin layer, the primary resin layer includes a cured ultraviolet curable resin composition containing 2,4,6-trimethylbenzoyldiphenyl phosphine as a photoinitiator, and the secondary resin layer includes tin and a cured ultraviolet curable resin composition containing 2,4,6-trimethylbenzoyldiphenyl phosphine as a photoinitiator, the content of 2,4,6-trimethylbenzoyldiphenyl phosphine is 0.5 to 2.0% by mass in the coating resin layer, a percentage of uncured components having a molecular weight of 1000 or less included in the coating resin layer is 15% by mass or less, and a fraction of an amount of a phosphorus-tin complex with respect to an amount of hydrocarbon on a surface of the coating resin layer is 1000 ppm or less, and a cured ultraviolet curable resin composition containing 25 to 45% by mass of a polyfunctional monomer having a bisphenol skeleton. 2. The optical fiber according to claim 1 , wherein a Young's modulus of the secondary resin layer is 800 MPa or more at 23° C. 3. The optical fiber according to claim 1 , wherein a Young's modulus of the secondary resin layer is 900 MPa or more at 23° C. 4. The optical fiber according to claim 1 , having an outer diameter of 260 μm or less. 5. The optical fiber according to claim 1 , having an outer diameter of 210 μm or less. 6. The optical fiber according to claim 2 , having an outer diameter of 260 μm or less. 7. The optical fiber according to claim 3 , having an outer diameter of 260 μm or less. 8. The optical fiber according to claim 2 , having an outer diameter of 210 μm or less. 9. The optical fiber according to claim 3 , having an outer diameter of 210 μm or less.
