光学仪器-编程可调光滤波器  OTF-930

台式可调光滤波器OTF-930可已根据客户要求选配滤波片型号和级数（S1,S2,S3），内部结构进行优化后，实现了80nm的波长调谐范围及超低插损。同时santec特有的“linear sliding”滤波片也具有低PDL、低PMD等特性。
OTF-930通过GPIB及RS-232接口，可以实现远程控制及数据采集。

性能特征 低插入损耗 80nm 波长调谐范围 低PDL (<0.1 dB) & 低 PMD (<0.1 ps) 0.01 nm 分辨率 GPIB接口
应用 放大信号ASE噪声抑制 WDM信号通道选择 Incoherent tunable light source combining with broadband light source
