Abstract The error extension of 4B‐3T code causes some problems to destuff error of the stuff indicating pulses. This paper investigates the characteristics of error extension associated with 4B‐3T code transmission, and proposes a method to eliminate the adverse effects of the error. Involved are the interlease and rearrangement of the stuff indicators, pulses in the binary code before conversion to ternary code. The optimum conversion method is described. An experimental 4B‐3T code transmission system is constructed to evaluate the characteristics of error extension and destuff error. Further, this system demonstrates that the proposed 16 bits interleave method results in a destuff error rate comparable to that of the AMI transmission method and only a few hundredth of that of the conventional 4B‐3T code transmission without interleave.
