ENET Transceiver/Media Converter - 1 x Network (RJ-45) - Fast Ethernet - 10/100Base-T, 100Base-X - 1 x Expansion Slots - SFP - 1 x SFP Slots

Media converters interface between two cable types. The most common use for media converters is to insert fiber for network extensions, up to 40 kilometers or more, beyond the 100-meter limit imposed by copper cable. Fiber media converters, also known as fiber transceivers or Ethernet media converters, are simple networking devices that make it possible to connect two dissimilar media types. Media converters are important in interconnecting fiber optic cabling-based systems with existing copper-based, structured cabling systems.
