Abstract
The present invention relates to an optical fiber containing a glass fiber and a coating layer in contact with the outer circumference of the glass fiber, and a method for manufacturing the optical fiber, in which the coating layer contains silane coupling agents represented by the following formulae (1) and (2): in the formulae, R1 represents a group capable of reacting with an acryl group or an acryl group, and R2 to R8 are each the same or different and represent an alkyl group.
Claims5
An optical fiber comprising a glass fiber and a coating layer in contact with the outer circumference of the glass fiber, wherein the coating layer contains silane coupling agents represented by the following formulae (1) and (2):
- wherein R1 represents a group capable of reacting with an acryl group by ultraviolet irradiation or an acryl group, and R2 to R8 are each the same or different and represent an alkyl group having 2 or more carbon atoms wherein the ratio of the silane coupling agent represented by the general formula (1) to the silane coupling agent represented by the general formula (2) in the coating layer is 1:11 to 11:1.
A method for manufacturing an optical fiber containing a glass fiber and a coating layer, comprising forming the coating layer so as to come into contact with the outer circumference of the glass fiber,
- wherein the coating layer is formed of a resin composition containing silane coupling agents represented by the following formulae (1) and (2):
- wherein R1 represents a group capable of reacting with an acryl group by ultraviolet irradiation or an acryl group, and R2 to R8 are each the same or different and represent an alkyl group having 2 or more carbon atoms wherein the ratio of the silane coupling agent represented by the general formula (1) to the silane coupling agent represented by the general formula (2) in the coating layer is 1:11 to 11:1.
