Ring Network Ethernet Switch

Ring network 4FE+4RS232 to 2SFP fiber media converter

This series of products using industry redundant ring network design each device has two fiber optic ring network for the port consisting of network topology annular cascade through holding hands industry redundant ring network (FC-Ring) is designed to achieve in the harsh environment the stability of data transmission reliability and timeliness. Its working principle is physical connection to a ring structure work the network signal into a chain structure once the transmission cable disconnection somewhere node device in a very short period of time automatically switched to the standby line transmission. Redundant ring network structure not only reduces the risk of data signal transmission but also simplifies installation and reduces the cost of the project.
This product offers: two Gigabit Ethernet SFP optical ports; four Fast Ethernet electrical interface; four serial interface for RS232/RS485/RS422. Support optional CONSOLE/WEB management built-in Lithium Battery.
◆ First built-in lithium battery with battery protection and charging function when the device is powered off the lithium can provide power for more than 1-2 hours to ensure that fiber optic ring network line is working (this function is optional);
◆ Industrial rail designed specifically for harsh industrial environments;
◆ Provide two gigabit fiber optic lines it can automatically switch when line fault to ensure normal communication;
◆ Support a variety of fiber-optic network structure: point to point star chain ring network redundancy and can be combined for more complex network topologies to support multiple optical network structure;
◆ Device provides four Fast Ethernet ports two gigabit optical Ethernet interfaces  the total transmission bandwidth of wire speed 1000M;
◆ Switch built 1Mbit MP-SSRAM high-speed memory non-blocking design the maximum backplane bandwidth 32GBit/S;
