10GBASE-CX specifications
The 10GBASE-CX is a 4-pair twinaxial copper cable that plugs into the SFP+ socket and
connects two 10 Gb ports. The reach for this cable is up to 15 m with a bit error rate (BER)
better than 10
-12
. The signaling speed for each lane is 3.125 GBd ± 100 ppm. 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 802.3ak standard. The following table identifies the part
numbers for specific cable lengths.
