1000BASE-DWDM SFP Transceivers
The Dense Wavelength Division Multiplexing (DWDM) SFP transceivers are part of a DWDM optical
network to provide high-capacity bandwidth across a fiber-optic network. There are 40 fixed-wavelength
DWDM SFP transceivers that support the International Telecommunications Union (ITU) 100-GHz
wavelength grid. These transceivers have duplex SC connectors. DWDM SFP transceivers can transmit
and receive optical signals up to 50 miles (80 km) depending on the quality of the fiber-optic cable used.
DWDM SFP transceivers look like the typical 1000BASE-X transceivers as shown in
