Managed Hardened Media Converter, 1000Mbps, 2xSFP

The IMC-574I is a value-based, managed Gigabit Ethernet solution that is ideal for use in a fiber infrastructure. The IMC-574I comes with two SFP ports and two fixed 10/100/1000Base-T copper ports. There are four distinct DIP switch selectable configurations to feature the IMC-574I to be a 1 plus 1 uplink port revertive mode, a 1 plus 1 uplink protection non-revertive mode, a 4-port Gigabit switch, and a dual copper to fiber SFP media/mode converter (two Gigabit fiber media converters in one) The term "1 plus 1" refers to line protection where identical information is transmitted on two lines. The receiver chooses its communication line based on the revertive or non-revertive configuration. When a fault is detected on the active line, the traffic is switched to the redundant line. In the non-revertive mode, data is not resumed back to the original line unless the backup line fails or is disconnected. Once the original line is no longer in a fault condition, data can be resumed back to the original line.
