Experimental confirmation:The gain and noise characteristic of 5 km DCF-50 km G652 fiber configuration dispersion compensation FRA is better than 50 km-G652-5 km DCF FRA and 25 km G652-5 km DCF-25 km G652 FRA.

• 实验证明:5kmDCF 50kmG652光纤色散补偿型分布式FRA的增益和噪声特性优于50km、G652 5kmDCF光纤和25kmG652 5kmDCF 25kmG652光纤色散补偿型分布式FRA。
