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 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
watts 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 Table 1-8 shows details of the cables supported:
