InfiniBand using 8B10B coding, which yields a data rate of 2 Gbps. The more capable 4X specification quadruples the signaling rate to 10 Gbps and the data rate to 8 Gbps by spreading a datastream over four bonded links. The 12X specification supports a signaling rate of 30 Gbps and a data rate of 24 Gbps. Double-rate and quad-rate options effectively double and quadruple each of these theoretical speeds.
