Extralink Nemezis Pro | PoE Switch | 48x RJ45 1000Mb/s PoE, 4x SFP+, 500W, L3

The 48-port Gigabit Smart PoE switch with 48 1000BASE-T PoE ports and four 10G SFP slots provides advanced management features with 256 Gbps switching capacity. The Extralink Nemesis Pro is equipped with 1000BASE-T PoE ports , which provide higher gigabit speeds of up to 1000 Mbps with existing Cat5e or better cabling. This switch provides 48 PoE connections with a maximum power budget of 500 wat ts and delivers up to 30 watts of power per port for devices such as access points, IP PTZ cameras and VoIP phone systems.
With data rates of 802.11ac wireless access points reaching as high as 1 Gbps, 100M ports cannot meet the bandwidth demand. Supporting speeds of 1 Gbps and 802.3af/at PoE output, the Extralink Nemesis Pro can not only deliver data to 802.11ac wireless access points, but also power other devices such as access points and IP cameras.
The Extralink Nemesis Pro provides higher throughput and powerful computing power. It offers a maximum uplink throughput of 40 Gbps through four 10 Gbps SFP ports . In addition, the administrator can flexibly choose the appropriate SFP/SFP module depending on the transmission distance or transmission speed required to effectively expand the network.
Achieving 6 kV surge protection, the Ethernet ports of the Extralink Nemezis Pro switch have immunity to lightning and other electrical surges, offering reliable operation even in harsh environments.
