Polarization-maintaining DWDM
Introduce
The 100G/200G polarization-maintaining DWDM ITU wavelength division multiplexers/PM filters/DWDM devices utilize environmentally stable thin-film filters 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 functions, or integrated into DWDM systems and fiber optic sensor systems.
Features
- High isolation
- ITU standard
- High stability and reliability
- Telcordia standard testing
Application
- Fiber optic amplifier
- Optical add-drop multiplexing system
- Laboratory research
