Title (EN) METHOD AND DEVICE FOR DETERMINING A PRESENCE OF A LOCKING SIGNAL IN A SIGNAL RECEIVED BY AN OPTICAL RECEIVER DEVICE.
(FR) PROCÉDÉ ET DISPOSITIF POUR DÉTERMINER LA PRÉSENCE D'UN SIGNAL DE VERROUILLAGE DANS UN SIGNAL REÇU PAR UN DISPOSITIF RÉCEPTEUR OPTIQUE
Abstract:
(EN) The invention relates to a method for determining a presence of a locking signal in a signal received by an optical receiver device, the optical receiver device being intended to be used in an optical communications network, the locking signal being a signal exchanged by optical communication devices of the optical communications network in a phase preceding setting up communications between said optical communication devices. The presence of the locking signal is determined by obtaining the direct current component or the component at twice a frequency at which the locking signal is supposed to be modulated, and by obtaining the contribution of the communication signal, if any, on said component.
(FR) L'invention porte sur un procédé pour déterminer la présence d'un signal de verrouillage dans un signal reçu par un dispositif récepteur optique, le dispositif récepteur optique étant destiné à être utilisé dans un réseau de communication optique, le signal de verrouillage étant un signal échangé par des dispositifs de communication optique du réseau de communication optique dans une phase précédant un établissement de communication entre lesdits dispositifs de communication optique. La présence du signal de verrouillage est déterminée par obtention de la composante continue ou de la composante à deux fois la fréquence à laquelle le signal de verrouillage est supposé être modulé, et par obtention de la contribution du signal de communication, si elle existe, sur ladite composante.
