城域网和接入网发展需要的低水峰单模光纤

Guangtongxin yanjiu, 2005
密集波分复用（DWDM）的出现扩大了长途传输网的容量,但是DWDM技术的复杂性和使用了昂贵的器件,限制了DWDM在城域网的应用。最新研制的光纤,其在整个宽工作带,包括在（1380±3）nm上都具有低水峰。低水峰光纤与粗波分复用（CWDM）系统比用标准单模光纤（SMF）的同一系统所用的信道间隔宽33%。经过恶劣的环境试验证明,低水峰光纤具有稳定的抗氢气引起的衰减性能,可确保现场安装的低水峰光纤光缆长期可靠地工作。由于低水峰光纤具有优异的弯曲敏感性,使其与最近研制的宽带接入技术,即所谓的光纤到驻地（FTTP）
