Dense Wavelength Division Multiplexer (Dense WDM)
Single channel
The Dense Wavelength Division Multiplexer DWDM series are designed and manufactured to Telcordial standard and ITU standard. The devices use environmentally stable Thin Film Filters and advanced packaging technology to achieve wide pass band, low insertion loss, high channel isolation and excellent environmental stability. They can be used individually to perform single channel add or drop function or can be cascaded into sequence for multi-channel applications in DWDM systems.


Dense Wavelength Division Multiplexer Mux/Demux
(4 /8/16 channel)
The multi-channel Dense Wavelength Division Multiplexer (DWDM) Modules are based on thin film DWDM devices by cascading individual channels into sequence. Channel numbers can be as high as 40(16) for 100(200)GHZ systems in C band or in L band, They are featured with wide pass band, low insertion loss, high channel isolation and high environmental stability. They can be used in Dense WDM systems to perform multiplexing or demultiplexing function.
