Vorrichtung und Verfahren zum Herstellen einer metallbeschichteten Glasfaser

摘要

An apparatus for fabricating an optical fiber coated with metal, constructed with a crucible for melting the optical fiber preform to draw an uncoated optical fiber, a diameter measuring device for measuring the diameter of the uncoated optical fiber to regulate it, a metal coater for coating the uncoated optical fiber with metal to prevent penetration of moisture, a temperature controller for controlling the inside temperature of the metal coater, a post-cooler for cooling the metaled optical fiber from a high temperature, a capstan for drawing the optical fiber from the optical fiber preform by applying a rotational force against a portion of the metaled optical fiber, and a spool for winding the metaled optical fiber. The metaled optical fiber includes a core for transmitting light, a cladding on the core having lower refractive index than the core, and a metal coating formed on the cladding for preventing penetration of moisture.
