Abstract
Official abstract text for this publication.
An optical fiber includes a glass fiber that includes a core and a cladding and a coating resin layer that coats the glass fiber by being in contact with the glass fiber. The coating resin layer includes a cured material of an ultraviolet ray curable resin composition having a dissolved oxygen concentration of greater than or equal to 8.5 mg/L.
First claim
Opening claim text (preview).
What is claimed is: 1. An optical fiber comprising: a glass fiber that includes a core and a cladding; and a coating resin layer that coats the glass fiber by being in contact with the glass fiber, wherein the coating resin layer includes a cured material of an ultraviolet ray curable resin composition having a dissolved oxygen concentration of greater than or equal to 8.5 mg/L. 2. The optical fiber according to claim 1 , wherein the dissolved oxygen concentration is greater than or equal to 8.5 mg/L and less than or equal to 35 mg/L. 3. The optical fiber according to claim 1 , wherein the dissolved oxygen concentration is greater than or equal to 8.5 mg/L and less than or equal to 25 mg/L. 4. The optical fiber according to claim 1 , wherein the coating resin layer includes a primary resin layer that coats the glass fiber by being in contact with the glass fiber, and a secondary resin layer that coats the primary resin layer by being in contact with the primary resin layer, and at least one of the primary resin layer and the secondary resin layer includes a cured material of an ultraviolet ray curable resin composition having a dissolved oxygen concentration of greater than or equal to 8.5 mg/L.
