  • PoE switch power supply distance

    PoE switch power supply distance

    In PoE (Power over Ethernet) technology, the Ethernet link between the Power Sourcing Equipment (PSE) and the Powered Device (PD) has a clearly defined maximum distance limit—100 meters (328 feet). 3bt (PoE++) are the three primary power supply specifications for PoE. This limitation is not arbitrary; it is defined by the IEEE Ethernet standards that govern PoE. The max PoE distance over Ethernet is 100 meters (328 feet) between a PoE power sourcing equipment (PSE) port and a powered device (PD). This PoE max distance is set in the IEEE 802. This limitation stems from the signal attenuation characteristics of twisted pair cables - the higher the data transmission rate, the more. PoE allows electrical power and network data to be transmitted together through a standard Ethernet cable (such as Cat5e or Cat6).
