4/8/16/24 Port Gigabit PoE Switch

Power Over Ethernet, Plug And Play Compliant with IEEE 802.3af/at POE standard, this gigabit unmanaged PoE switch 4 port can automatically detect and identify PD devices that comply with the standard and supply them with power through the network cable. 250 Meters Extend Transmission Automatically detect the transmission distance and adjust the transmission rate, extend up to 250m(820ft) data and power PoE transmission range (Speed will drop to 10 Mbps).   PoE Auto Recovery It can intelligently detect the data exchange between the PoE port and the terminal device. When an abnormality is detected, it will automatically restart and return to normal without affecting other ports, reducing maintenance costs. QoS for Fluent Experience Qos function of gigabit poe switch can optimize network management by monitoring traffic and usage. Reduce network data latency to ensure stable and reliable data transmission.
