For CWDM and DWDM applications we can supply 8 or 16 channel mux / demux units in small form factors ideally suited for use in video modular products. The filters are bidirectional and can be terminated with SC or LC connectors. The filters combine directly with the range of CWDM SFP Video Optical Modules from Gennum Corporation for use in the 1270 - 1410 nm and 1470 - 1610 nm bands. The 8 way filters have an "express" channel that allows the filters to be cascaded making a 16 way solution.

We also have a wide range of optical passive components including circulators, switches, couplers, attenuators and patchcords. Please contact use for more information and for inquiries on custom optical designs.
