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 Table 52: DWDM X2 Transceivers
, on page 222, there 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 Figure 148: 10-Gigabit
X2 Transceiver (Latching Sleeve Not Extended), on page 219.
For the specifications that differentiate the 10GBASE-DWDM X2 transceivers, see the http://www.cisco.com/
