The 4CH Mini CCWDM (Compact CWDM) MUX/DEMUX is a 4-channel CWDM
device with super compact package designed for cost-effective multi-wavelength CWDM
network applications. It is based on the Thin Film Filter (TFF) technology and free-space
technology platform. It operates at 4 channels 20nm channel spacing ITU Grid CWDM
wavelengths from 1270nm to 1610nm. It is ideal for functioning with inexpensive,
uncooled lasers. With up to 4 low dispersion channels, it is a high capacity, low cost
product for 40G/100G, CATV, and metro/access network applications. We provides
a series of customized 4CH Mini CCWDM MUX/DEMUX devices packaged in metal box to meet different requirements on port configuration (1310nm and upgrade ports available),operating wavelength, fiber type, fiber length, input connector, and output connector
