4B/5B Coding

4B/5B Coding. In 4B/5B, the 5 bit output that replaces the 4 bit input has no more than one leading zero and two trailing zeros. So when different groups are combined to make a new sequence there are never more than three consecutive 0s Some unused groups are used for control purposes
