1000BASE-DWDM SFP Transceiver Specifications

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 the following figure.
