Abstract
A data stream (b(t)) including high ('1') and low ('0') logical states is transmitted over an optical link by means of an optical source adapted to be driven via the data strema, to generate an optical signal for transmission over the optical link. The optical signal includes optical pulses generated at the occurrence of high logical states in the data stream b(t). The input data stream b(t) is coded into a coded data stream B(t) prior to the transmission over the optical link. The coding step minimizes the logical high states in the coded data stream, and the optical source is driven by means of the coded data stream wherein the number of logical high states has been minimized.
