概述光学元件

滤光片 数据通信的光学滤光片

借助这些滤光片 低插入损耗、低波长依赖性(PDL)和高信道隔离度的滤光片 将数据中心收发器 扩展至100G甚至更高。

These filters enable construction of high-performance, reliable, 100G CFP/CFP2/CFP4/QSFP-28 transceivers based on the four CWDM4 wavelengths, the four LAN-WDM wavelengths, or the 850 nm wavelength range.

CWDM4 and LAN-WDM Filters

Choose CWDM4 or LAN-WDM filters at low angles of incidence (AOIs) or specify WDM filters for high AOIs plus beamsplitters with low polarization splitting.
