摘　　要：介绍了耐高温金属衣层光纤的用途、特点及制作工艺。分析了金属衣层光纤的热应力,探讨了金属衣层材料的物理特性(弹性模量、热延展率和泊松比)以及衣层的厚度对热应力的影响。通过选择性能较好的金属材料以及控制镀层的厚度来减少金属衣层光纤的热应力,从而得到金属衣层光纤的优化设计方法。The purposes,characteristics and process of metal-coated optical fibers with high temperature-resistance are introduced.The thermal stresses in metal-coated optical fibers are analyzed.The physical properties（Young’s modulus,Thermal expansion coefficient,Poisson’s ratio） of the metal coating and its thickness had an effect on thermal stresses is discussed.There is an optimal design by appropriately selecting physical properties of the metal coating and its thickness.

关 键 词：金属衣层光纤 热应力 优化设计
