Title (EN) OPTICAL NETWORK TESTING
(FR) TEST DE RÉSEAU OPTIQUE
Abstract: front page image
(EN)A method includes generating a test signal and modulating the test signal. The method may also include transmitting the test signal on an optical path, where the optical path may include a number of add-drop multiplexer devices and amplifiers. The method may also include receiving the test signal at a destination device and converting the received test signal into an electrical signal. The method may further include identifying a portion of the electrical signal that is associated with the modulated test signal.
(FR)L'invention porte sur un procédé qui comprend la génération d'un signal de test et la modulation du signal de test. Le procédé peut également comprendre la transmission du signal de test sur un trajet optique, le trajet optique pouvant comprendre un certain nombre de dispositifs multiplexeurs à insertion-extraction et d'amplificateurs. Le procédé peut également comprendre la réception du signal de test au niveau d'un dispositif de destination et la conversion du signal de test reçu en un signal électrique. Le procédé peut en outre comprendre l'identification d'une partie du signal électrique qui est associée au signal test modulé.
