4GE+4RS232+2SFP Ring Network Switch

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 Gigabit 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 GigabitEthernet 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

● FPGA + ARM-based design, rapid self-healing back to shorten the settling time, support the “FC-Ring” Redundant Ring (recovery time <20ms);

● Support the transmission of extra-long VLAN packets that can support IEEE802.1Q protocols Items matching switches use;

● Have a broadcast storm protection, balanced flow, isolate the conflict and error detection and other functions;

● 10/100/1000Mbps adaptive electrical ports MDI / MDI-X adaptive without manual adjustment,

● Ethernet interfaces with serial data with lightning protection, lightning reached GB / T17626.5 (IEC61000-4-5) Short circuit current wave 8 / 20μs, open standard peak output voltage 6KV

● The device comes with WEB management platform, online software upgrades, the host side can manage the work of each state machine equipment;

● Supports a wide range of AC and DC input (9V-48V), supports internal isolation, redundant dual power inputs, power support overload protection, anti-reverse protection

● Meet industry four electromagnetic compatibility requirements
