Our take on the Cisco 10Gb/s Cx4 10GBase-CX4 Ethernet X2 Module

The Cisco 10GBase-CX4 X2 module is a 10-gigabit Ethernet transceiver that plugs into an X2 slot on a Cisco switch or router and carries traffic over a short CX4 copper cable. It is a legacy 10G option: CX4 tops out around 15 meters and uses bulky, stiff cable, while SFP+ has largely replaced it. It suits owners of older X2-equipped gear who need a cheap 10G copper uplink between racks, not new deployments.

Pros
  • 10 Gb/s over short CX4 copper runs
  • Plugs into standard X2 slots on supported Cisco gear
  • Copper cabling avoids the cost of optics
  • Simple plug-in module with no configuration
Cons
  • CX4 is a legacy standard, superseded by SFP+
  • Roughly 15-meter cable limit
  • Bulky, inflexible CX4 cables
  • Only works in X2 slots, not SFP+ cages

Questions and answers

What is this module used for?
It gives an X2-equipped Cisco switch or router a 10 Gb/s Ethernet port over a short CX4 copper cable, typically within a rack or between adjacent racks.
How far can the CX4 cable run?
CX4 copper is specified for about 15 meters. Longer runs need fiber or a different 10G interface.
Will it fit my switch?
Only if your device has an X2 slot and supports this module. It will not fit SFP+ or QSFP cages.
Is CX4 still a good choice?
Only for existing X2 hardware. New builds use SFP+ or DAC cables, which are smaller, cheaper and more widely supported.
Does it need configuration?
No. It is a physical-layer transceiver; the port is configured on the switch itself.
Where is the Cisco 10Gb/s Cx4 10GBase-CX4 Ethernet X2 Module cheapest?
At Gotodirect, for $169.31, as of our latest check.
