                                  BLACK BOX Extreme Media Converter Switches do more than just adapt from one cable type to another. They're true Ethernet switches and behave like switches within your Ethernet network. This means you can connect them together indefinitely without worrying about interrepeater links. Each Media Converter Switch features non-blocking switching architecture with a 2K MAC address table. The 128K buffer memory makes it easy to interconnect 10- and 100-Mbps devices.

                                  Tough enough for outdoor use.

                                      Unlike the Ethernet switches in your wiring closet or computer center, the Ethernet switches at the edges of your network have to put up with the bumps, the dirt, the dampness, and the temperature fluctuations that happen out in the real world. This is where Heavy-Duty Edge Switches from Black Box come in.

                                      These Heavy-Duty Edge Switches are tough, 6-port copper Ethernet switches that enable you to expand your network even into harsh environments such as factory floors or the outdoors. They're ro
