Two fragments of a fiber-optic data transmission line are considered round and elliptical (at the junction) in their cross section. For a single-mode operation, analytical expressions are obtained for the energy losses when connecting two such fragments. It is shown that energy losses increase with increasing eccentricity and simultaneously decrease with increasing waveguide number.

两根光纤分开时的能量损失，其中一根在连接处椭圆形变形

光纤数据传输线的两个片段的横截面被认为是圆形和椭圆形（在连接处）。对于单模运行，当连接两个这样的片段时可获得能量损失的解析表达式。结果表明，能量损失随着偏心率的增加而增加，同时随着波导数的增加而减少。
