PROCEDURE FOR THE COMPENSATION OF BITS DURATION VARIATIONS IN SIGNAL TRANSMISSION SYSTEMS BY OPTICAL FIBER AND RESINCRONIZER FOR THE PERFORMANCE OF THE PROCEDURE.

摘要

Procedure for the elimination of logical states of time durations, which deviate from the theoretical course, of digital signals transmitted by optical fiber, by at least one optoelectric transformer (O / E transformer), and an electro-optical transformer (transformer I / O), connected in the transmission path, as well as resynchronizers having a regulation member, connected in an intermediate manner, directed by a regulation signal, characterized in that the duration of time of, respectively, the same number of bits, one after the other, of the same polarity (series of bits) of both the High and Low logic states of the digital signal derived from the signal branch that joins the two transformers, is measured continuously, stored in an intermediate way, as well as mutually compared, and because, from the difference of these time durations (time deviation), the regulation signal is generated, whose input signal , supplied by the O / E transformer, influences the regulating member, so that the time deviation is compensated by temporal displacement of at least one edge of the bit series, and the High and Low bit series of the signal of Output supplied to the I / O transformer have the same magnitude.
