GS728TP is Gigabit PoE/ PoE+ Smart Switche that comes with PoE capabilities on all ports and supports PoE+ with up to 30W of power budget on the first 8 ports, providing hardware investment protections so that the switch can support many more PoE powered devices and higher-powered devices down the road. There has also been an addition of high-powered PoE+ Smart Switch into the portfolio. It also comes with 4 dedicated Gigabit SFP ports for fiber connectivity.
TL-SG1005P is a 5 10/100/1000Mbps ports unmanaged switch that requires no configuration and provides 4 PoE (Power over Ethernet) ports. It can automatically detect and supply power with all IEEE 802.3af compliant powered devices. In this situation, the electrical power is transmitted along with data in one single cable allowing you to expand your network to where there are no power lines or outlets, where you wish to fix devices.
