单模光纤种类繁多,在光缆链路中不可避免地会出现不同类别光纤相互连接的情况。从模场直径、折射率、截止波长、衰减、色散、偏振模色散、非线性效应等方面分析了光纤混接后可能对链路性能的影响。并列出了各类光纤与兼容性相关的部分性能要求。
A wide range of single-mode fiber, the optical cable link will inevitably appear in different types of optical fiber interconnection situation. From the aspects of mode field diameter, refractive index, cutoff wavelength, attenuation, dispersion, polarization mode dispersion and non-linear effect, the influence of the possible fiber coupling on the link performance is analyzed. And lists some of the performance requirements for various types of fiber related to compatibility.
