Copper Cable
Types of Copper Cables
A copper cable, also known as the Direct Attach Copper (DAC) cable, consists of connectors and copper wires and is easy to use. It can directly connect to an optical port on a device. The difference between copper cables and AOC cables is that copper cables use copper wires to transmit signals, whereas AOC cables use optical fibers to transmit signals.
Table 9-22 shows the types of copper cables.

The two ends of a copper cable must be covered by electrostatic discharge (ESD) caps.
- The SFP-10G-CU1M and SFP-10G-CU2M copper cable can connect the S6730-H28Y4C or S6730-H24X4Y4C to the S5700-28C-HI-24S (used the LS5D00X4SA00 card), S5720-28X-LI-AC, S5720-28X-LI-24S-AC, S5720-28X-LI-24S-DC, S5700-28X-LI-24S-AC, S5700-28X-LI-24S-DC, S5700-28X-LI-AC, and S5701-28X-LI-24S-AC. The SFP-10G-CU2M can only be used for interconnection between the preceding devices.

Stack Description
In addition to data transmission, copper cables can be used for stack connection.
Before setting up a stack, familiarize yourself with the device-supported stack connection modes and software and hardware requirements. For details, see "Determining the Stack Connection Support and Mode" under "Typical Stack Configuration of Fixed Switches" in the Typical Configuration Examples.
