JetNet 3806G - Industrial Networking Solutions – Industrial Ethernet Switches and Routers

JetNet 3806G



JetNet 3806G is a PoE Boost Switch designed with 4 Fast Ethernet PoE ports and 2 Gigabit uplink ports to ensure high-bandwidth uplink connection for large-scale surveillance in transportation system networks. JetNet 3810G integrates Korenix patented vehicle PoE technology – the 12V to 48V power booster for making the deployment of standard PoE IP cameras feasible on buses, railcars, ships, etc. Moreover, the compact size with aluminum alloy metal enclosure allows JetNet 3806G to reliably operate under -25~60℃ wide temperature range applications.

For Bus/Railway PoE

JetNet 3806G, designed with Korenix patented DC 12V to 48V boost technology, is the best solution for the vehicle PoE applications, where DC 48V power supply is not available. With the built-in power booster, the JetNet 3806G can be powered by DC 12~24V to deliver 15.4W per port and 60W* per unit at DC 48V to PoE-enabled devices such as IP cameras, PoE Wireless APs, PoE IP phones…etc. and therefore, be easily applied in vehicles or carriages.  JetNet 3806G provides a fast, easy and cost-effective solution for configuring PoE networks on transportation and automation applications.
