EDFA掺铒光纤放大器分类


1.功率放大器(booster-Amplifier),处于合波器之后,用于对合波以后的多个波长信号进行功率提升,然后再进行传输,由于合波后的信号功率一般都比较大,
所以,对一功率放大器的噪声指数、增益要求并不是很高,但要求放大后,有比较大的输出功率。
2.线路放大器(Line-Amplifier),处于功率放大器之后,用于周期性地补偿线路传输损耗,一般要求比较小的噪声指数,较大的输出光功率。
3.前置放大器(Pre-Amplifier),处于分波器之前,线路放大器之后,用于信号放大,提高接收机的灵敏度(在光信噪比(OSNR)满足要求情况下,较大的输入功率可以压制接收机本身的噪声,提高接收灵敏度),要求噪声指数很小,对输出功率没有太大的要求。
