摻鉺光纖(EDF)
產品介紹
北億纖通科技有限公司提供全系列摻鉺光纖產品,可滿足最苛刻的光放大器設計要求以及ASE光源設計,放大范圍覆蓋C波段和L波段。C-Band和L-Band摻鉺光纖都可以采用1480nm和980nm泵浦。該摻鉺光纖采用特有的摻雜技術制作,光纖具有良好的批次一致性和光譜性能的重復性,可以和通信光纖低損耗連接,具有極其出色的機械性能。
產品特點
● 高一致性,批次光纖光譜重復性好,不需要匹配增益平坦濾波器(GFF)
● 嚴格的光學性能和機械性能公差
● 出色的纖芯同心度,低損耗連接
● 詳細的批次光纖特性數(shù)據(jù)提供
應用范圍
● C-Band和L-Band光纖放大器
● 小型化ASE光源
● 小尺寸光纖放大器
