BLACK BOX® Extreme Media Converter Switches do more than just adapt from one cable type to another. They're true Ethernet switches & behave like so. This means you can connect them together indefinitely without worrying about interrepeater links.
Function as both a media converter and a switch.
Suitable for harsh outdoor environments.
Provide one 100-Mbps fiber port and two 10-/100-Mbps UTP switch ports.
RJ45 ports support autonegotiation, so you can easily attach any 10- or 100-Mbps device.
Support both half- and full-duplex operation.
Two sets of LEDs enable you to see status information from the front, top, or side.
Rackmount up to 16 units in the optional Rackmount Tray or Powered Rackmount Tray (available separately).
