SFW-D Dense Wavelength Division Multiplexer (DWDM)

Couplers, Splitters Wavelength division multiplexers (WDM, CWDM, DWDM)

SFW-D series dense wavelength division multiplexer and demultiplexer (DWDM) modules are reliable solutions to multiservice applications. They multiply the capacity of existing singlemode fibers, based on 100 or 200 GHz channel spacing. The SFW-D are available in a variety of packaging options for standard configurations of 4, 8, 16, 32 and 40 channels. Custom devices can be configured to meet customer demands concerning channel counts, wavelength plan and packaging requirements.

Wide channel bandwidth
High adjacent channel isolation
Low polarization dependent loss and chromatic dispersion
