PoE power supply distance of the switch
The standard PoE switch distance limit is 100 meters, as defined by Ethernet transmission properties. When the transmission distance exceeds 100 meters, data delay, packet loss, etc. Because the farther the distance, the greater the resistance, the higher the requirements. 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). The pair 1-2 act as the positive polarity, while the pair 3-6 act as the negative polarity.

Standard power supply pins for PoE switches
PoE utilizes specific pins within the standard RJ45 pinout to transmit power alongside data. The exact pins used depend on the PoE mode employed: Mode A: This mode, the more common standard in modern PoE devices, uses pins 1, 2, 3, and 6 for power transmission. Power over Ethernet is a technology that allows IP telephones, wireless LAN Access Points, security network cameras and other IP-based terminals to receive power, in parallel to data, over the existing CAT-5 Ethernet infrastructure without the need to make any modifications. We know that there are different types of network cables available such as cat6, cat7, cat5, etc, and different types of ports also available such as RJ45. But have you ever stopped to consider the intricate wiring that makes this technology possible? Understanding the PoE pinout – the specific. Proper PoE pinouts support easy device installations, reduce cable clutter, and enable remote power supply.
