Easily expand or upgrade your home or business network with fast and energy-saving Gigabit connectivity. Optimized for intensive 4K video streaming, video surveillance, large downloads, and online conferences. The DGS-105GL is a plug-and-play device that requires no complex configuration. You can connect multiple computers within minutes and share an internet connection, files, music, and videos in your office or home network. With Gigabit transfer rates on all ports, file transfers between connected devices are completed in a flash. Using 802.1p Quality of Service (QoS), the switch automatically organizes and prioritizes time-sensitive and essential data to deliver them efficiently, enabling seamless video streaming without buffering and smooth video and voice calls. The DGS-105GL operates without fans, ensuring silent operation, reduced energy consumption, and increased reliability by eliminating a potential point of failure. Its robust and compact metal housing is designed for a wide temperature range, dissipating heat and reducing stress on internal components. Thanks to its compact metal casing and fanless design, the switches can be operated virtually anywhere and without noise. Energy efficiency was also a key consideration in the development of the DGS-105GL. The switches automatically reduce power to inactive or unused ports and support the IEEE 802.3az Energy-Efficient Ethernet standard.
