Abstract
A method for transmitting on an optical connection an input data sequence having first and second logic states, includes encoding the input data sequence prior to transmission on the optical connection, where the encoding minimizes the first logic states in the encoded data sequence. The encoding includes: arranging the input data sequence in parallel on a number of bus lines; counting the first logic states in the input data sequence; comparing the counting result with a value equal to half of the lines; and logically inverting the input data sequence on the lines if the counting result is greater than half of the lines of the input data sequence. The method further includes: ordering values of the input data sequence; identifying the first value having the first logic state; and applying the encoding operation just to the ordered values subsequent to the first value having the first logic state.
