A coding scheme is provided transporting encoded information over an optical
communications
link to a network. Multi-word information groups are analyzed to determine whether
each of the information groups includes control characters. If the information
group does not include any control characters, an encoded information stream including
a set data indicator and data words is generated. If the information group includes
one or more control characters, an encoded information stream is generated which
includes control code counters, a transition indicator, location pointers, control
codes that are encoded from the control characters, and any data. Accordingly,
the necessary bandwidth for transporting the information is reduced by using this
encoded information stream without sacrificing any control information.
