PM DWDM (100 G, 200 G)

产品详细信息

The PMDWDM series is designed and manufactured according to Telcordia standard and ITU standard, it preserves the polarization of optical signals. The devices use environmentally stable thin film filter and advanced packaging technology to achieve wide passband, low insertion loss, high channel isolation, excellent environmental stability and high extinction ratio. They can be used individually to perform single channel add or drop function or can be used in DWDM systems and fiber sensor systems, etc.
