Industrial Ethernet Switch – JetNet 3018G

industrial ethernet switch jetnet3018g


The Korenix JetNet 3018G is an Industrial Ethernet Switch, equipped with 16 RJ-45 10/100Mbps ports and 2 10/100/1000TX with 1000-SX SFP combo ports. The SFP ports accept all types of Gigabit SFP Transceivers, such as Gigabit SX, LX, LHX, ZX and XD for several connections and distances. The JetNet 3018G also supports Jumbo frame transmission, up to 9216-bytes packet size, which is crucial especially while the industrial applications requesting the transmission with large size files. The JetNet 3018G adopts the rigid aluminum case, the unique Korenix-Design, which is the right option for the hazardous environments.

  • 16 10/100-TX and 2 Gigabit RJ-45/SFP combo ports (10/100/1000 Base-TX, 1000Base-X)
  • Non-Blocking Switching Performance
  • Supports up to 9,216 bytes Jumbo Frame Packet for secured large file transmission
  • 2 Relay Outputs for Gigabit port Link Failure Detection
  • IEEE 802.1p Quality of Service (QoS) for packet forwarding precedence
  • Auto Gigabit RJ-45/SFP module detection
  • IP31 rugged aluminum case
  • Dual 24V (12-48V) DC power inputs
  • Operating temperature -25~70oC
