10GBASE-DWDM X2 Transceivers
The Dense Wavelength Division Multiplexing (DWDM) X2 transceivers are part of a DWDM optical
network to provide high-capacity bandwidth across a fiber-optic network. As listed in
are 32 fixed-wavelength DWDM X2 transceivers that support the International Telecommunications
Union (ITU) 100-GHz wavelength grid. These transceivers have duplex SC connectors. DWDM X2
transceivers can transmit and receive optical signals up to 50 miles (80 km) depending on the quality of
the fiber-optic cable used.
DWDM X2 transceivers look like the typical 10GBASE-X X2 transceivers as shown in
page
For the specifications that differentiate the 10GBASE-DWDM X2 transceivers, see the 10-Gigabit
Ethernet Transceiver Modules Compatibility Matrix.
