ICCSZ訊 2019年3月18日,Dimension(www.dimension-tech.com)推出高性能光學(xué)濾波器POF-80-CL。這款高性能的超窄帶寬和波長可調(diào)光學(xué)濾波器(Ultra-Narrow Bandwidth-Variable Tunable Filter),是一個電控的光學(xué)帶通濾波器,帶寬和波長可以同時調(diào)諧,并可進(jìn)行編程控制,還可以實(shí)施遠(yuǎn)程調(diào)控。它具有前所未有的超窄帶寬,最小可達(dá)30pm(3.7GHz),帶寬調(diào)節(jié)范圍從30pm到3nm(370GHz),可調(diào)中心波長范圍從1525nm到1615nm,具有前所未有的邊帶抑制比,高達(dá)1500dB/nm(12dB/GHz)的滾邊斜率。
POF-80-CL具有平頂帶通響應(yīng),陡峭的濾波邊緣,前所未有的帶外抑制比。另外,該濾波器還具有插入損耗低、偏振無關(guān)、PDL可忽略等特性。更重要的是,POF-80-CL有特殊光學(xué)設(shè)計(jì),不論調(diào)諧在哪個位置,引入的色散幾乎可忽略,并且還有雙向工作的選項(xiàng)。這些特性是其他同類產(chǎn)品不具有的。
POL-80-CL超窄帶寬和波長可調(diào)光學(xué)濾波器可適用于WDM,CWDM,DWDM信道濾波,OFDM信號的窄帶濾波,無色散光譜濾波,光纖傳感,光信號選擇/抑制,ASE噪聲抑制,光信號自適應(yīng)濾波及可變通帶的應(yīng)用,以及EDFA、OSNR/NF 增益和微弱信號接收和提取等。
