The TP-Link TL-SG1048 is a 48-port Gigabit Ethernet unmanaged switch designed for workgroup, departmental, and network infrastructure applications. It provides 48 × 10/100/1000 Mbps RJ45 ports, with automatic speed negotiation and Auto MDI/MDIX for straightforward plug-and-play connectivity.
The switch uses a non-blocking wire-speed architecture with a 96 Gbps switching capacity and supports IEEE 802.3i, 802.3u, 802.3ab and 802.3x standards. It is housed in a 1U, 19-inch rack-mountable steel chassis, making it suitable for server rooms, network cabinets, and other structured-network installations.
