PROCEDE ET SYSTEME DE CONTROLE DE LA TRANSMISSION DE SIGNAUX OPTIQUES

摘要

The optical signal control method has defined transmission channels (Ci) with a step of insertion of a control signal (S). The signals are regrouped on the same fibre and multiplexed. The modulation process modulates simultaneously the band (B) multiplexed signals as a function of the control signal providing carrier control signals for each signal.
