10Gb/s EML-TOSA及其在中长距离光通信中的应用

摘要

The work principle, subassembly structure, main performance of 10Gb / s EML TOSA were introduced .According to test results and comparing, They have given out of "1" code level and the peak to peak modulation voltage optimum condition for EAM ;The dynamic spectrum, eye diagram, dispersion tolerance and impedance matching problems of l0Gb/s EML TOSA have analysed and discussed;They have pointed out that the dynamic spectral width and the dispersion Penalty for l0Gb/s EML TOSA is smaller.%介绍了10Gb/s EML-TOSA的工作原理、主要结构和性能；通过调测和比较,给出了EAM的“1”码电平和峰-峰调制电压最佳条件；分析、讨论了10Gb/s EML-TOSA的动态谱宽、眼图、色散容限和阻抗匹配等问题；指出了10Gb/s EML-TOSA具有动态谱宽较小,色散代价较小的特点,在中、长距离实用化光通信中将有广泛的应用.
