详细介绍

波长可调谐滤波器OTF-930是一款偏振无关的80nm可调滤波器。Santec的"Linear Sliding"技术使得在PDL,带宽和插入损耗等光学特性恒定不变的情况下,进行准确持续的波长调谐。OTF-930能实现非常低的插入损耗。OTF-930利用串联的形式增加滤波隔离来实现最小的插损增益。OTF-930的十几款型号基本覆盖了绝大部分的光纤应用。

  • 80nm可调范围
  • 低插入损耗
  • 低PDL(<0.1dB)&PMD(<0.1ps)覆盖所有可调范围
  • 0.01nm波长分辨率
  • 使用LabView软件驱动,支持GP-IB
  • ASE噪音抑制
  • 波长选频
  • 波长可调谐激光器:相干光源
  •  

    应用举例 光通信收发器信号劣化强度确认
