Dispersion Characteristics in Optical Fiber Transmission

基于光纤传输对于光纤通讯技术的重要意义,数值模拟光纤传输过程中的色散关系,得到随着光纤长度的增加,光纤传输中比特率减小,当入射波长为1.28μm时,光纤色散为0ps.nm-1.km-1,研究结论为光纤传输器件设计提供理论依据。

Based on the optical fiber transmission has a significance effect on optical communication technology,and the dispersion relation in optical fiber transmission was numerically simulated.The optical fiber transmission bitrate reduced along with increase fiber length,when the incidentwavelength was 1.28μm,optical fiber dispersion was 0ps·nm-1·km-1.The results provide the theory basis for designing of optical fiber transmission devices.
