Industrial grade gigabit optical multiplexer switch is a new generation of multi service access network management Gigabit redundant Ethernet switch, which has the characteristics of high integration, rich functions, simple and convenient, and represents the highest level in the industry. It contains 8ch Gigabit ethernet port, 16 way gigabit optical port and 4 gigabit SFP/UTP combo port, especially suitable for video transmission and other occasions with 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 temperature, has strong anti electromagnetic interference, anti salt fog, anti shock and anti shake, meets the strict working environment requirements of industrial site, and provides efficient, reliable and fast solutions for industrial Internet of things.
