【摘要】 本文推导出级联EDFA密集波分复用系统光信噪比表达式,并由EDFA噪声指数的定义推导出级联EDFA系统等效噪声指数的表达式,分析了级联EDFA系统输出端OSNRout与等效噪声指数之间的关系,并通过实验对之加以了验证。更多还原

【Abstract】 In this paper , the expression of optical signal-to-noise(OSNR) and effective noise figure of cascade EDFAs in DWDM systems are derived.They also introduce the expression of noise figure for a system consisting of a chain of EDFAs according the definition of individual EDFA.The relationship between the two expressions has been analyzed in this paper.更多还原
