Coated optical fiber, optical fiber tape core using it and optical fiber unit |
摘要 |
The present invention provides a coated optical fiber in which a silica type optical fiber is coated with n layers (n being an integer of 2 or greater) of UV-curable resin, wherein the sum of respective contraction stress indices FI defined in the n layers of UV-curable resin by the following expression: FI [N]=(Young's modulus [MPa] of the UV-curable resin layer at -40° C.)x(cross-sectional area [mm<2>] of the UV-curable resin layer)x(effective linear expansion coefficient [10<-6>/° C.]/10<6>)x(temperature difference 190[° C.]) is 3 [N] or less. The present invention can sufficiently prevent transmission characteristics from deteriorating in a low temperature environment.
