Multiplexer Optical 3CH CWDM MUX Module 5G Backbone Network 1310/1490/1550nm
Product Overview
CWDM Mux Demux
CWDM Mux/Demux (optical multiplexer/demultiplexer) Module are considered as a cheaper and simpler alternative to DWDM systems for metro access network applications. Since CWDM Mux/Demux systems have wide channel spacing (20 nm), they do not require precise wavelength control for transmitter lasers. Thus, cost-effective non-cooled lasers as well as lower-cost passive components may be used for CWDM Mux or Demux systems. GEZHI Photonics supplies a variety of WDM devices and are promoting higher speed and more reliable optical network.
