10GBASE-CX specifications
The 10GBASE-CX is a 2-pair twinaxial copper cable that plugs into the SFP+ socket and connects
two 10-gigabit ports. The reach for this cable is up to 15 m with a bit error rate (BER) better than
10
-12
.
The 10GBASE-CX is a lower cost alternative to the optical SFP+ devices.
For more information about the 10GBASE-CX, including test and measurement information and
more specifications, see the IEEE 802.3–2012 standard. The following table identifies the part
numbers for specific cable lengths.
