The high bandwidth of 10 Gigabit Ethernet poses challenges to transmissions that are met by the transceiver and
cabling options supported by the Cisco Nexus 5000 Series.
The product family supports an innovative Twinax copper cabling solution that connects to standard SFP+
connectors for in-rack use, and optical cabling for longer cable runs (Table 2).
For in-rack or adjacent-rack cabling, the Cisco Nexus 5000 Series supports SFP+ direct-attach 10 Gigabit
●
Ethernet copper, an innovative solution that 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
watt (W) of power per transceiver and introduce only approximately 0.25 microsecond of latency per link.
For longer cable runs, the Cisco Nexus 5000 Series supports multimode, short-reach optical SFP+
●
transceivers. These optical transceivers use approximately 1W per transceiver and have a latency of less
than 0.1 microsecond.
Both these options provide lower latency and higher energy efficiency than 10GBASE-T. This standard uses
transceivers that consume 4 to 8W per transceiver and contribute a latency of up to 2.5 microseconds per link,
making the 10GBASE-T standard a significant contributor to network-level power consumption.
