Coating forming device of optical fiber

Abstract

An optical fiber coating forming device forms a coating of an ultraviolet light hardening type in an optical fiber by precisely controlling an ultraviolet light output of a light source. The optical fiber coating forming device has a light source (2) for irradiating ultraviolet light to resin for coating formation molded to a coating removing portion (4) of an optical fiber core wire (3), a light receiver (5) for detecting intensity of the ultraviolet light by receiving the ultraviolet light irradiated to the resin for coating formation from the light source (2), and an environmental sensor (20) for detecting environmental information. The environmental sensor (20) includes at least a temperature sensor (6) and selectively includes a humidity sensor (7) and an atmospheric pressure sensor (8). An optical output controller (1) feedback-controls the optical output of the light source (2) on the basis of the environmental information detected by the environmental sensor (20), the ultraviolet light intensity detected by the light receiver (5), and control data for controlling the optical output of the light source (2) based on the ultraviolet light intensity and the above environmental information.
