The Application Of PoE Long-distance Power Supply Technology

- Apr 02, 2021-

PoE technology is developing rapidly at Present. With a series of advantages such as simplified installation and deployment of electrical equipment, and safety, energy saving and high efficiency, PoE technology has become widely used in project scenarios such as wireless network coverage and security video surveillance.

However, the maximum effective PoE transmission distance is 100 meters. In projects such as wireless coverage and security monitoring, if the terminal equipments are deployed too scattered, and the distance between a single node and the switch is too far, The application of PoE power supply technology will be severely restricted.


◆ PoE Long-distance Power Supply Technology

Aiming at the problem that the effective PoE transmission distance is less than 100 meters. HRUI has independently developed a series of network transmission equipment supporting long-distance power supply, covering PoE switches, PoE extenders and other products. Through the application of these technical equipment, on the basis of ensuring the smooth transmission of high-definition data signals, the maximum transmission distance of PoE power supply can be increased to 1KM, which greatly improves the coverage of wireless communication and video surveillance.


◆ Application Solution

1、Extend:250 Meters

HRUI PoE switch adopts self-developed high-power power chip, and supports one-key smart function: VLAN, Default, and Extend. The Extend mode, the network speed drops to 10M, and the maximum transmission distance can reach up to 250 meters.

2、PoE network repeater

Under the standard mode, The 3-port 10/100M industrial-grade PoE switch HR500-ATG-21 can be used as a network repeater.

After turns on the Extend mode, the network speed drops to 10M, the PoE transmission distance can reach up to 250 meters, and the overall PoE power supply solution has a maximum transmission distance of 350 Meter.

3、800 Meter PoE extender

HRUI-PE08-SV and HRUI-PE08-IPC is a pair of 800m PoE extenders, using advanced network cable drive and power supply technology. The switch is connected to HRUI-PE08-SV/IPC equipment in standard mode. After dialing to 10M rate mode, the PoE transmission distance can reach up to 800 meters. And the overall PoE power supply solution has a maximum transmission distance of up to 1KM, breaking the network transmission limit.
