The Vi-Link EN22 Industrial Web Managed Ethernet Switch is designed to operate in a high-temperature NEMA environment with 2* 10/100/1000Mbps TX and 2* 1000Base LX SFP. It is primarily intended for large, higher speed/bandwidth-demanding workgroups that require expansion of the Ethernet network. It can extend the conventional 10M, 100M, or 1000M Ethernet to 20Km~100Km via the SFP Gigabit Fiber-optical Line. It is a high-performance, cost-effective, and flexible solution for a wide range of applications in the field of LAN campus networks.
With its built-in Web-based management, the EN22 offers an easy-to-use and configuration facility, via the WEB interface, it can be programmed for basic management functions such as port speed duplex settings, Port Trunking, VLAN, Port Mirroring, network security authentication, and misc configurations. Additionally, the firmware includes advanced features such as IGMP snooping, QoS (Quality of Service), broadcast storm, and bandwidth control, to enhance bandwidth utilization. The extended temperature capability for meeting NEMA specifications satisfies very critical applications requiring high-quality data transmission performance with high reliability.
Applications include ITS Intelligent Traffic System, Metro Operation, HDTV Broadcasting System, IP cameras Surveillance, Homeland Security, Utility Management, Premise Networks, Military Hardened applications, or anything requiring high-speed Ethernet Network performance.
