WDM Optical Networking Solutions
WDM (Wavelength Division Multiplexing) is a concept that describes combination of several streams of data/storage/video or voice on the same physical fiber optic cable by utilizing several wavelengths (or frequencies) of light with each frequency carrying a different sort of data. There's two types of WDM architectures: CWDM (Coarse Wavelength Division Multiplexing) and DWDM (Dense Wavelength Division Multiplexing). CWDM systems typically provide 18 wavelengths, separated by 20 nm, from 1470nm to 1610nm according to ITU-T standard G.694.2. However, for different applications, there are different ITU-T standard to define the specific wave range and channels. Compared to CWDM, DWDM is defined in terms of frequencies. Some DWDM network systems provide up to 96 wavelengths, typically without any more than 0.4 nm spacing, roughly over the C-band range of wavelengths.
CWDM network are a flexible, low-cost solution that enables the expansion of existing fiber capacity and let operators make full of use of available fiber bandwidth in local loop and enterprise architectures. Our CWDM Mux/Demux units are universal devices capable of multiplex CWDM (1270~1610nm) up to 18 channels or optical signals into a fiber pair or single fiber. Rollball provides full complete configuration like 2, 4, 5, 8, 9, 16, 18 channels. Optional wide band for existing 1310nm or 1550nm to multiplex with these CWDM channels. Fully utilize with the existing equipments. Together with our CWDM transceivers or the wavelength converters, the bandwidth of the fiber can be utilized in a cost effective way.
DWDM Mux/Demux units are universal devices provide the most robust and low-cost bandwidth upgrade for fiber optic communication networks. Rollball provides full complete configuration like 8, 16, 20, 24, 32 channels with different housing types. OEM is available.
