When using traditional fiber converters, users often encounter the following problem: a fiber converter acted like an ordinary 2-port switch. When one of a fiber converter's ports failed (e.g. the TX port), the other one (e.g. FX port) would continue to receive data via the media (e.g. fiber), confusing the device on the other end of the media that the connection was still intact. But, by the time the disconnection was found, this error had caused a great amount of loss.

On the other hand, JetCon 2301 Industrial Ethernet Converter not only can trigger the alarm system by relay output the moment that one of the ports fails, but also activate the Link Lose Forwarding to shut down the other port, allowing the device on the other end of the media to detect the disconnection. The administrator over the network can be informed of the disconnection immediately, and react promptly to the situation, greatly reducing loss caused by any link failures.
