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 3).
●
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.

Features and Benefits
The Cisco Nexus 5000 Series’ rich feature set makes it ideal for top-of-rack, middle-of-row, or end-of-row access-
layer applications. It protects investments in data center racks with standards based 10 Gigabit Ethernet and FCoE
features, and virtual machine awareness features that allow IT departments to consolidate networks based on their
own requirements and timing. The combination of high port density, lossless Ethernet, wire-speed performance, and
extremely low latency makes the switch family ideal for meeting the growing demand for 10 Gigabit Ethernet that can
support unified fabric in enterprise and service provider data centers, protecting enterprises’ investments. The switch
family has sufficient port density to support single and multiple racks fully populated with blade and rack-mount
servers.
●
Built for today’s data centers, the switches are designed just like the servers they support. Ports and power
connections are at the rear, closer to server ports, helping keep cable lengths as short and efficient as
possible, delivering benefits traditionally offered on blade servers to rack servers as well. Hot-swappable
power and fan modules can be accessed from the front panel, where status lights offer an at-a-glance view of
switch operation. Front-to-back cooling is consistent with server designs, supporting efficient data center hot-
and cold-aisle designs. Serviceability is enhanced with all customer-replaceable units accessible from the
front panel. The use of SFP+ ports offers increased flexibility, enabling use of a range of interconnect
solutions, including copper Twinax cable for short runs and fiber for long runs.
