    BLACK BOX® Hardened Media Converter Switches do more than just adapt from one cable type to another. They're true Ethernet switches and behave like switches within Ethernet networks - especially those situated in or near harsh industrial areas. This means you can connect them together indefinitely without worrying about inter-repeater 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 the factory floor!
    Hardened Media Converter Switches are for dusty or dirty environments with temperatures that range between -13 and +140° F (-25 to +60° C). They use the metal case as a heat sink so no internal airflow is needed for cooling. The case is sealed to resist environmental contaminants such as dust, dirt, moisture, smoke, and insects. They're an ideal choice for demanding industrial applications such as factory floors.

    Media Converter Switches are also available in Standard versions for office or wiring closet environments and Extreme versions for outdoor environments. Because all three types work together seamlessly, you can use inexpensive Standard Media Converter Switches in the protection of the wiring closet and choose the more robust Hardened or Extreme Media Converter Switches for harsh locations at your network's edge.

    Distance isn't a problem.
    Because they're switches as well as media converters, Media Converter Switches provide more options in network topology, overcoming the distance limitations inherent with simple media converters - to add extra distance, just daisy-chain another Media Converter Switch. If you need more ports at your remote location, just add a BLACK BOX® Convenient Switch (LB101HA family).

    Multimode models support up to 2 kilometers (1.2 miles) between Hardened Media Converter Switches. For longer distances, choose single-mode models for up to 20 kilometers (12.4 miles) or single-mode, long-distance models for an incredible 40 kilometers (24.8 miles) between links.

    The features you're looking for.
    Media Converter Switches are super simple to set up and use - just plug and go! Both copper ports are autosensing for speed and duplex, adjusting to the connected device automatically. Plus, the UTP ports feature Auto MDI/MDIX, eliminating the need for crossover cables.

    Media Converter Switches each have two full sets of LED indicators: one set on the front for viewing convenience when the Media Converter is DIN rail or wall-mounted, and one set mounted in the end next to the media ports for easy viewing when units are in a rackmount tray.
