ICCSZ讯 2019年3月18日,Dimension(www.dimension-tech.com)推出高性能光学滤波器POF-80-CL。这款高性能的超窄带宽和波长可调光学滤波器(Ultra-Narrow Bandwidth-Variable Tunable Filter),是一个电控的光学带通滤波器,带宽和波长可以同时调谐,并可进行编程控制,还可以实施远程调控。它具有前所未有的超窄带宽,最小可达30pm(3.7GHz),带宽调节范围从30pm到3nm(370GHz),可调中心波长范围从1525nm到1615nm,具有前所未有的边带抑制比,高达1500dB/nm(12dB/GHz)的滚边斜率。
POF-80-CL具有平顶带通响应,陡峭的滤波边缘,前所未有的带外抑制比。另外,该滤波器还具有插入损耗低、偏振无关、PDL可忽略等特性。更重要的是,POF-80-CL有特殊光学设计,不论调谐在哪个位置,引入的色散几乎可忽略,并且还有双向工作的选项。这些特性是其他同类产品不具有的。
POL-80-CL超窄带宽和波长可调光学滤波器可适用于WDM,CWDM,DWDM信道滤波,OFDM信号的窄带滤波,无色散光谱滤波,光纤传感,光信号选择/抑制,ASE噪声抑制,光信号自适应滤波及可变通带的应用,以及EDFA、OSNR/NF 增益和微弱信号接收和提取等。
