Title
(EN) COMMON-MODE DATA TRANSMISSION FOR POWER OVER ETHERNET SYSTEM
(FR) TRANSMISSION DE DONNEES EN MODE COMMUN POUR SYSTEME A ALIMENTATION ELECTRIQUE PAR CABLE ETHERNET (POE)
Abstract
(EN) Circuitry and methodology for providing data transmission in a Power over Ethernet (PoE) system having a Power Sourcing Equipment (PSE) for providing power to a PoE link, and a Powered Device (PD) coupled to the PoE link for receiving the power from the PSE. The PSE and PD support data communication with each other in a common mode between two pairs of lines in an Ethernet twisted pair cable.
(FR) La présente invention concerne des ensembles de circuits et un procédé permettant de mettre en oeuvre la transmission de données dans un système à alimentation électrique par câble Ethernet (Power over Ethernet (PoE)) comprenant un équipement d'alimentation électrique (PSE) conçu pour fournir de l'électricité à une liaison PoE, et un dispositif électrique (PD) couplé à la liaison PoE conçu pour recevoir l'électricité provenant de l'équipement d'alimentation électrique. L'équipement d'alimentation électrique (PSE) et le dispositif électrique (PD) sont conçus pour permettre la transmission de données de l'un vers l'autre dans un mode commun entre deux paires de lignes dans une paire de câbles torsadés Ethernet.
