Optical fiber preform fabricating apparatus

摘要

An optical fiber preform fabricating apparatus capable of simultaneously mounting and fabricating a plurality of preforms and adaptable according to the length of performs is provided. The apparatus heats a plurality of quartz tubes using at least one burner to deposit chemical reactants on the outer walls of the quartz tubes. To this end, the apparatus includes a chamber housing extending longitudinally and a variable-length structure mounted within the chamber housing in a longitudinal direction, wherein the variable-length structure is adjustable in accordance with the length of the quartz tubes and horizontally moves back and forth in the longitudinal direction.
