级联EDFA光通信系统传输特性研究

Study on Transmission Characteristics of Optical Communication Systems with Cascaded EDFAs

研究由级联掺铒光纤放大器(EDFA)构成的光纤通信系统的光信噪比和误码率的性能指标,给出光放大器级联系统的光信噪比和误码率之间关系的一般表达式,并分析了信号串扰对误码率的影响,在此基础上得出新的误码率表达式。

The performance indices of OSNR and BER in optic communication system with cascaded EDFAs are studied systematically and a general expression between OSNR and BER is deduced. The influence of crosstalk on BER is analyzied and then a new expression of BER is presented.
