可编程波长&带宽可调谐滤波器OTF-970
中心波长和带宽可调
Santec开发的OTF-970是一款通用的可编程光学可调谐滤波器，实现了中心波长和C&L波段的带宽同步独立可调。OTF-970基于新的自由空间光学配合超精细调谐机制，以确保***的过滤控制和平顶的通带形状。
※OTF-970将于2019年3月底停止生产。
替代产品：OTF-980
根据传输带宽范围和斜坡形状的不同有两种版本可供选择。标准款(Standard type)：0.1-15nm可调带宽，200dB/nm侧波斜率。超精细款(Ultra-Fine)具有0.08-4nm可调带宽和极为陡峭的侧波斜率400dB/nm。OTF-970具有自动调节滤波中心波长和带宽的功能。此外，在输出端口配有集成功率计以便实时监测光功率并具备自动峰值搜索功能。符合工业标准的SCPI命令集的GPIB和USB接口可实现全面的远程控制与测量自动化。
