OPTICAL FIBER MANUFACTURING METHOD WHICH HAS AN IMPROVED BENDING LOSS PROPERTY, CAPABLE OF FORMING A SECOND CLAD LAYER THROUGH A OVERCLADDING BONDING PROCESS BY USING A PREPARED TUBE, AND AN OPTICAL FIBER THEREOF

摘要

PURPOSE: An optic fiber manufacture method and an optical fiber thereof are provided to reduce process time and improve productivity.;CONSTITUTION: A core(a) is located in the center. A first cladding layer(b) is formed in the adjacent of the core. A second cladding layer(c) is formed in the neighboring of the first cladding layer. A third cladding layer(d) is formed in the neighboring of the second cladding layer. The maximum refractive index of the core is greater than that of the first cladding layer, the second cladding layer, and the third cladding layer. The maximum refractive index of the second cladding layer is less than that of the first cladding layer and the third cladding layer.;COPYRIGHT KIPO 2010
