Coarse Wavelength Division Multiplexing Dual Band

CWDM Dual Band filters are used to transmit one or more standard CWDM channels in two separate bands, also available for custom band width design in each band.

Iridian’s dual band filters have proved to be very popular in recent CWDM designs as they can reduce the number of required filters (and the associated packaging and alignment), minimize insertion loss and allow more compact module packaging.
