CWDM 2×0 Comb Filter
Iridian now offers CWDM comb filters. Comb filters are alternating pass/reflect band of a given channel spacing (2x0 or 1x0). These comb filters provide CWDM module designers more options in minimizing packaging cost and size. The standard bandwidth of the pass/reflect channels is 15nm with a transmission isolation greater than 15 dB and a reflection isolation greater than 13 dB
