使用掺铒光纤放大器的光接收机特性的研究

Optical Receiver Using Er+ Doped Fiber Amplifier

本文从理论上对强度调制－直接检测ＷＤＭ光传输系统中使用掺铒光纤放大器做前放的光接收机灵敏度及功率恶化进行了分析和计算。采用近似方法导出了光接收机灵敏度的数学表达式。

:In this paper,we calculate and analyse the sensitivity and power penalty of the optical receiver on theory in IDDI WDM system which uses EDFA as preamplifier.Through approximate method,the concrete expression of sensitivity is derived.
