CWDM Dual Band High AoI

High AOI dual band filters are designed for meeting the needs of cCWDM (compact CWDM) Demux modules. They 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. The high AOI dual band CWDM filters inherit our low AOI dual band filter’s functionality and performance.
