SFP+ Copper Cables
Copper cables are available for use with the 10-Gigabit Ethernet SFP+ module (see Table 1-5). The cables come in the following lengths:
•1 m, 30 AWG
•3 m, 28–30 AWG
•5 m, 26–28 AWG

Cables
On the Cisco Nexus 5500 Platforms, you can use an innovative Twinax copper cable that connects to standard SFP+ connectors for in-rack use and on the optical cable for longer cable runs.
For in-rack or adjacent-rack cabling, the Cisco Nexus 5500 Platform supports SFP+ direct-attach
10-Gigabit Ethernet copper, which integrates transceivers with Twinax cables into an energy efficient, low-cost, and low-latency solution. SFP+ direct-attach 10-Gigabit Twinax copper cables use only
0.1 W of power per transceiver and introduce only approximately 0.25 microsecond of latency per link.
For longer cable runs, the Cisco Nexus 5500 Platform supports multimode, short-reach optical SFP+ transceivers. These optical transceivers use approximately 1 W per transceiver and have a latency of less than 0.1 microsecond.
Table 1-7shows details of the cables supported.
