超窄带宽可调谐滤波器
CVF-300是目前市场上带宽最小的可调谐滤波器，同时具有高达1500dB/nm（12dB/GHz）的滚边斜率。带宽和中心波长同时可调，并可进行编程控制，实施远程调控。可用于DWDM信号的信道滤波，OFDM信号的窄带滤波，ASE噪声抑制，以及EDFA、OSNR/NF 增益和微弱信号接收和提取等。
* 生产线自动化检测系统 * DWDM系统的窄带滤波 * 脉冲整形和ASE噪声滤波 * 量子通信，量子秘钥 * 光纤传感
产品特点 典型应用 * 波长覆盖C&L波段
* 超快滚边率1500dB/nm
* 市面上最小的输出带宽30pm (3.7GHz)
* 输出波长和带宽均可调谐
