| 摘要 |
The invention relates to an apparatus and a method for manufacturing a hermetically coated optical fiber (3), the apparatus having a single reaction chamber (25) into which a bare fiber (1) and raw gas are to be introduced for applying a hermetic coating to the bare fiber (1) while the bare fiber (1) passes through the reaction chamber (25). The reaction chamber (25) has a plurality of inlet tubes (25a, 25b, 25c, 25d) to introduce the raw gas, and the plurality of inlet tubes are open to the reaction chamber (25) at different positions from each other in a direction of movement of the bare fiber (1) passing through the reaction chamber (25). <IMAGE> |
