The TL-SG1005D 5-Port Gigabit Ethernet Switch allows you to upgrade your old network to a 1000Mbps network at an affordable cost. Increase the speed of network servers and backbone connections and make the Gigabit desktop a reality. More demanding users in home, office, workgroup or creative production environments have the ability to move large bandwidth-intensive files faster. Transferring graphics, CGI, CAD files, multimedia files and other applications that require moving large files is almost instantaneous. 5 RJ45 ports 10/100/1000Mbps auto data negotiation (Auto-MDI/MDIX). Automatically shut down ports that have no connection, and reduce output power based on cable length. Featuring Green Ethernet technology, the TL-SG1005D promotes energy saving and reduces network costs. It supports IEEE 802.3x flow control in Full Duplex mode and backpressure flow control in Half-Duplex mode. Non-blocking switching architecture that forwards and filters packets at their maximum throughput. It supports MAC address machine learning and auto-aging. Easy to use and offers high performance.
