Iridian’s Dual Pass Band Filter features two pass bands in one filter chip. This filter allows for modern CWDM designs that reduce the number of required filters, minimize insertion loss and allow smaller packaging.
To meet the needs of cCWDM (compact CWDM) Demux modules, Iridian has recently developed high AOI dual band filters to make free space Demux module design possible using our multiband filters. These filters are designed for AOI’s from 10 to 13.5 degrees and cover the full band blocking wavelength range from 1260 to 1620 nm. Iridian’s high AOI dual band CWDM filters inherit our low AOI dual band filter’s functionality and performance.
