For example, a data octet of 11001010 might be expressed the first time as 1000100111, and the second time as 0111011000.That encoding scheme yields direct current (DC) electrical balance on the line, as the number of 1s and 0s will be equal in the long term. This approach also ensures proper clocking as there is sufficient ones density. 8B/10B also provides an additional embedded error control mechanism similar to that discussed in 4B/5B, which is used in 100Base-TX. On the down-side, 8B/10B adds 25 percent overhead (10/8 = 1.25) to the serial datastream. Note: The 10B format also provides for a number of control characters. 8B/10B is used in 10 Gigabit Ethernet (10GbE or 10GigE), Gigabit Ethernet (GbE or GigE), ESCON and Fibre Channel Storage Area Networks (SANs). See also 10 Gigabit Ethernet, 4B/5B, 64B/66B, balanced, DC, encode, ESCON, Fibre Channel, GigE, ones density, and line coding. |
