Abstract: A mass production method of and apparatus for hermetically coating optical fiber (1) where a bare fiber (1) drawn from a preform is hermetically coated by CVD method in a reactor vessel (2), wherein a liquid (13) flushes solid particles or by-products sticking to the reactor inner wall. The liquid (13) may be supplied continuously or intermittently, to flush carbon particles generated during carbon coating process. The invention enables to produce a long hermetic coating optical fiber (1) without choking the reactor, and improves a yield rate and productivity.
