Ring Network Ethernet Switch

8GE+4SFP(GE) Ring Ethernet Switch

This series of products using industrial redundant ring network design four Gigabit optical ports can be ring you can achieve the function of the tangent ring industrial redundant ring network design is to achieve in harsh environments the stability of data transmission Reliability and real-time. Its working principle is the physical connection into a ring structure the work of the network signal into a chain structure once the transmission cable somewhere node break the device in a very short time automatically switch to the backup line transmission. Redundant ring network structure not only reduces the risk of data transmission but also simplifies the installation of the project reducing the cost of the project.
This product provides: 4 Gigabit SFP Ethernet port; 8 Gigabit Ethernet interface.
