Product Description

16 Channels Optical WDM Device Filters Mux Demux CWDM 1U Rackmount 8 Channel CWDM MUX


DYS is a manufacturer for famous WDM users and customers. We continuously tried to improve product quality, introducing OPTRUN coating machine from Japan , and have coating capacity ,which make the film stable and good quality , The WDM full parameter testing system,which has been developed by our team,has highly improve the WDM device and modules testing efficiency and data integrated services. we also do vertical integration ,this ensure the high quality and delivery in time.We accumulated product development and managerial experience in fiber optic field to satisfy different requirements.


Coarse Wavelength Division Multiplexing (CWDM) is an excellent choice for increasing bandwidth capacity while keeping costs down. The 6com splice/pigtailed ABS module family, based on standard Thin Film Filter (TFF) technology with a proprietary packaging, offers you smallest component dimensions combined with an outstanding performance and reliability.
