Managed Rackmount 24-Port Gigabit UTP + 4-Port Gigabit SFP/UTP Combo Industrial Switch

Industrial grade 24 + 4 gigabit optical switch is a new generation of multi-service access network management Gigabit redundant Ethernet switch, with high integration, rich functions, and simple and convenient features, representing the highest level in the industry. It contains 24 Gigabit Ethernet ports and 4 gigabit optical ports, especially suitable for video transmission and other occasions with a large data stream.

It supports rich layer-2 management protocols for industrial switch applications, and supports ITU g.8032 redundant ring network protocol. The self-healing time is less than 20ms, which ensures the real-time and stability of the network. The switch adopts mature technology and open network standard, adapts to low temperature and high temperatures, has strong anti-electromagnetic interference, anti-salt fog, anti-shock, and anti-shake, meets the strict working environment requirements of industrial sites, and provides efficient, reliable, and fast solutions for industrial Internet of things.
