The coat which includes the primary coat material whose gelation speed is quick the optical fiber and the optical fiber coat system null

摘要

This invention the optical fiber coating system and offers the optical fiber which coating is done. According to one execution example of this invention, the optical fiber which coating is done the primary coating material which includes the optical fiber and the said optical fiber which possess the core and clad and, consists of, the said primary coating material young's modulus is below approximately 5MPa, as for the said primary coating material gelation time is the hardening reaction item of the short primary hardening composition from approximately 1.4 seconds in the ultraviolet ray strength of 3.4 mW/cm2.
