Fiber media converters make the connection between different media in Ethernet networks - fiber to copper. This way fiber media converters extend the otherwise limited to 100M distance by the twisted pair cable up to ranges reaching 80km depending on the integrated fiber port or on the used SFP. Standalone Ethernet media converters are ideal to integrate in older copper networks, giving them both extended range and higher EMI resistance which makes fiber media converters ideal to use in electric noise surroundings.
