Compact CWDM

VSunlight’s Compact CWDM series of multi-channel filters are used to increase/decrease several sets of CWDM optical wavelengths, of which the wavelength is 1271,1291......1611 nm in the CWDM ITU grid (20 nm spacing), and the number of common channels is 4CH, 8CH,18CH.. The filter has the advantages of small size, low insertion loss and so on. All versions are designed for outdoor use with temperatures ranging from -40℃to +85℃.
