Redundant Fast Ethernet media converters provide fiber or copper link redundancy. In the event that one cable link is broken, the redundant link is enabled to ensure 100% uptime. Redundant converter modules can provide link fault detection and switch over in 100 microseconds or less to provide rapid response time required for mission-critical network applications. Redundant links can run in parallel paths or geographically diverse paths (as shown in the fiber example below).
