For the specifications that differentiate the 1000BASE-DWDM SFP transceivers, see the Cisco Gigabit
Ethernet Transceiver Modules Compatibility Matrix. For specifications and installation information that apply
to all CWDM SFP transceivers, see the Cisco SFP and SFP+ Transceiver Module Installation Notes.
1000BASE-T and 1000BASE-X SFP Transceiver Specifications
The 1000BASE-T and 1000BASE-X SFPs are hot-swappable transceivers that you plug into SFP-compatible
I/O modules. The 1000BASE-T transceiver, shown in the following figure, provides an RJ-45 connection for
copper cables.
