Connector Specifications
10 Gigabit Ethernet CX1 (SFP+ Copper) Connectors
The 10-Gigabit Ethernet electrical modules use CX1 copper connectors similar to the one shown in
Figure B-2.
Note When ordering or using CX1 cables, ensure that the version identifier is 2 or higher.
The 10-Gigabit Ethernet optical modules use the connectors shown in Figure B-3 and Figure B-4.
Figure B-2 10-Gigabit Ethernet CX1 Copper Connector (example)
SFP and SFP+ Modules
Figure B-3, Figure B-4, and Figure B-5 show the SFP module connectors.
The Catalyst 3560-X switch supports the SFP module patch cable, a 0.5-meter, copper, passive cable
with SFP module connectors at each end (
Figure B-6). This cable can be used (only with 1-Gigabit
Ethernet SFP ports) to connect two Catalyst 3560-X switches in a cascaded configuration.
