两种实现方式的改进型光双二进制性能分析
Performance analysis of modified optical duobinary in two different implementation methods
摘要
Abstract
This paper studies by simulation two kinds of modulation formats for modified optical duobinary.It first compares and analyzes the structures of the transmitters that generate these formats,and their code type and spectrum characteristics. Afterwards,it simulates the system transmission performances.The results show that when the residual dispersion is large, the modified type Ⅱ optical duobinary modulation format has better performance.However,within the incident optical power range of -13.2 ~ 2.8 dBm,the modified type I optical duobinary modulation format has the highest Q value and hence the strongest resistance to nonlinear effects compared with the modified type Ⅱ optical duobinary and NRZ modulation formats.关键词
