The Gigabit Uplink Port To Guarantee the Transmission Smooth and StableIt provides 8 10/100M RJ45 ports and 1 gigabit port. By using CAT5e twisted pairs, it can provide power and data transmission to APs, IP cameras, IP phones, and so on, fully loadedTransmission Distance up to 250mWith the extension technology,data can be transmitted through 250 meters cable which would be a cost-effective replacement for extenders and optical fibers.Excellent Lightning ProtectionThe switch supports 6 kV lightning protection for uplink port, protecting the switch from thunderstorms and making it more stable.What's Special for TEF1109TP-8-102W :Simple Port VLAN SetupWith VLAN Mode on , ports 1 to 8 are isolated from each other, enabling the switch to isolate broadcast storm, improving LAN security and data transmission.Network standards IEEE 802.3?
