Fiber media converters are usually used in pairs to extend the transmission distance of copper cabling systems. But in the process of using, if one side of the link fails, the other side of the media converter will continue to work, and will not send an error report to the administrator. In this case, fiber media converter with FEF function can perfectly solve this problem. Next, we will introduce...
