Dense Wavelength Division Multiplexer
The Dense Wavelength Division Multiplexer series is designed and manufactured based on Telcordia standard and ITU standard. The devices use environmentally stable thin film filter and advanced packaging technology to achieve wide pass band, low insertion loss, high channel isolation and excellent environmental stability. They can be used to perform single channel add or drop function or can be cascaded into sequence for multi-channel applications in DWDM systems.
