掺铒光纤(EDF)
产品介绍
北亿纤通科技有限公司提供全系列掺铒光纤产品,可满足最苛刻的光放大器设计要求以及ASE光源设计,放大范围覆盖C波段和L波段。C-Band和L-Band掺铒光纤都可以采用1480nm和980nm泵浦。该掺铒光纤采用特有的掺杂技术制作,光纤具有良好的批次一致性和光谱性能的重复性,可以和通信光纤低损耗连接,具有极其出色的机械性能。
产品特点
● 高一致性,批次光纤光谱重复性好,不需要匹配增益平坦滤波器(GFF)
● 严格的光学性能和机械性能公差
● 出色的纤芯同心度,低损耗连接
● 详细的批次光纤特性数据提供
应用范围
● C-Band和L-Band光纤放大器
● 小型化ASE光源
● 小尺寸光纤放大器
