Industrial grade L3 core layer switch is a layer 3 network management Ethernet Switch independently developed by TH that is positioned at the convergence layer and core layer applications. It is a large-port and high-specification product in the industrial control field. This product adopts the industry's leading Technical standards, can provide stable and reliable Ethernet transmission, with high-quality design and reliability. It can provide users with high-efficiency bandwidth and reliable optical fiber network solutions for Ethernet data exchange, convergence and remote optical transmission. The product has the characteristics of no fan, low power consumption, high reliability, good stability, and easy maintenance. Industrial Ethernet Switch adopt mature technology and open network standards, adapt to low temperature and high temperature, strong anti-electromagnetic interference, anti-salt fog, anti-vibration and anti-shake, equipped with redundant dual power supply (AC/DC), which can offer redundant mechanisms for critical applications that need always-on connections. It can also operate at standard operating temperature range -40 to 75°C. Industrial switches support standard 19” rack mounts with IP40 protection and are perfect choices for harsh environments, such as industrial networking, intelligent transportation systems (ITS) and are also suitable for many military and utility market applications where environmental conditions exceed commercial product.
