8B/10B Translation Table

Table B.3 displays the 8B/10B (8-bit to 10-bit) translations between data bytes and 10-bit code-groups that are used for 1000BASE-SX, 1000BASE-LX, 1000BASE-CX, and fibre channel transmission.

Table B.3 uses conventions that were used in the 802.3 standards:

• The binary form of each 8−bit data byte is written with the most significant bit at the left.

• Each binary 10−bit code−group is written with the least significant bit at the left.

• Each 10−bit code−group is written as a 6−bit subblock followed by a 4−bit subblock.

The name assigned to a data code−group is based on the two parts of the binary expression and is

D(decimal value of 5−bit part).(decimal value of 3−bit part)

There are two ways to translate each byte, depending ...
