The TP-LINK 5-Port Gigabit Desktop Switch TL-SG1005D offers an easy way to transition to Gigabit Ethernet. Increase the speed of your network servers and backbone connections, or make Gigabit a reality in your workplace. Additionally, the TL-SG1005D is designed for lower power consumption. With the innovative, energy-efficient technology of the TL-SG1005D, you can save up to 70% energy, making this device an environmentally friendly solution for your office network. When a computer or network device is turned off, the corresponding port of a traditional switch continues to consume a significant amount of power. The TL-SG1005D automatically detects the link status of each port and reduces the power consumption of the ports that are idle, saving up to 70% energy in this case. Ideally, shorter cables would consume less power because less energy is lost over the length of the cable. However, this is not the case with most devices, as the same amount of energy is sent over the cable regardless of the length used.
