Claims

[Claims for Utility Model Registration] (1) A reaction chamber in which a hermetic coating is applied to an optical fiber inserted therethrough, and a reaction chamber provided in communication with one side of the reaction chamber with the optical fiber passing through it, a gas seal chamber into which active gas is introduced;
an air seal chamber provided in communication with the other side of the reaction chamber with the optical fiber passing therethrough and into which air is introduced; and an air seal chamber provided in the reaction chamber on the side of the gas seal chamber and the hermetic coating inside the reaction chamber. 1. A hermetic coating device comprising: an inlet for introducing a raw material gas for use in the coating; and an outlet provided in the reaction chamber on the side of the air seal chamber for discharging the reaction gas in the reaction chamber to the outside. (2) A reaction chamber that hermetically coats the optical fiber that is inserted through it, and a gas seal that is provided in communication with one side of the reaction chamber with the optical fiber passing through it and into which an inert gas is introduced. room and
an inlet provided in the reaction chamber on the side of the gas seal chamber for introducing the raw material gas for the hermetic coating into the reaction chamber; and an inlet provided in the reaction chamber on the opposite side of the gas seal chamber to introduce the reactant gas in the reaction chamber. A hermetic coating device characterized by comprising a discharge port for discharging the water to the outside.
