An optical fiber coating spreader comprises a spreader casing and an end cover. A conical coating liquid cavity and a water cooling cavity are formed in the spreader casing, a feed port is formed in the spreader casing, the feed port is communicated with the conical coating liquid cavity, the end cover is buckled at an upper end port of the conical coating liquid cavity of the spreader casing, and an optical fiber through hole is formed in the end cover. The optical fiber coating spreader can effectively guarantee optical fiber coating concentricity. The eccentricity of a coating layer can reduce the abrasion resistance of the coating layer to cause additional optical loss. The optical fiber coating spreader can guarantee strict alignment of end faces of optical fiber connectors, guarantees that the deviation of optical fibers is smaller than + / -2millimeters, can reduce optical loss of the optical fiber connectors, is suitable for various coating materials of polyurethane, ethylene fuel, nylon, thermoplastic rubber, FED, DFA and the like and can enable the coating thickness to meet design requirements.
Description
technical field [0001] The invention relates to the field of laser technology, in particular to an optical fiber coating coater used for optical fiber coating. Background technique [0002] In order to protect the optical fiber from being scratched and scratched and to isolate the low-loss optical fiber from the external environment, the optical fiber should be coated. [0003] For optical fibers, surface cracks can generally be classified as hot defects or cold defects. Thermal defects include stones, crystallization or similar defects. Cold defects include scratches, bruises, abrasions, etc. Coating must be carried out before the surface of the fiber has no cracks. [0004] Optical fiber coating, for a specific material, the thicker the coating, the stronger the anti-wear ability and anti-microbend loss ability. However, if the coating layer is too thick, the cross-section of the optical fiber will increase. When the optical fiber adopts a layered arrangement, the impa...
