Abstract
A system for precoating a preform for drawing optical fiber including a diameter sensor to determine a diameter of pulled optical fiber, a cooling system to cool the optical fiber once it is pulled from a furnace, a coating system to apply a coating to the optical fiber once it has cooled and an ultra-violet lamp to cure the coating.
Claims17
A system comprising:
- a vacuum chamber to hold a preform, wherein a gas is applied within the vacuum chamber with the preform from which an optical fiber is pulled;
- at least one sensor to measure a parts per million (PPM) of water moisture level within the vacuum chamber;
- an environmental control unit to provide a closed system within the vacuum chamber having at least a molecular sieve and a filter membrane to remove water moisture to maintain water moisture level at a given range;
- a coating system to apply a coating to the fiber pulled from the preform while the PPM of water moisture level remains within the given range and to apply a coating to the surface of the pulled fiber;
- and
- an ultra-violet lamp to illuminate an ultra-violet light to cure the coating.
