network media converters

100 Mbps Copper, 100-Mbps Fiber, Multimode, 100–240-VAC, ST - Function as both a media converter and a switch.
- Suitable for dusty or dirty environments with a temperature range between -13 and +140º F (-25 to +60º C).
- Provide one 100-Mbps fiber port and two 10-/100-Mbps UTP switch ports.

Further Details
- RJ-45 ports support autonegotiation, so you can easily attach any 10- or 100-Mbps device.
- ST, SC, MT-RJ, and LC fiber port types available.
- Available with 100–240-VAC and 12-, 24-, and 48-VDC power supplies.
- 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 (sold separately).
- For outdoor environments, see our Extreme Media Converter Switches (LBH100A-P and LBH110A-P families). Standard office-grade versions (LBH100A, LBH110A families) are also available.

These Media Converter Switches from Black Box are the versatile way to extend your network. They're easy to use—literally plug-and-play—and offer many choices of fiber types, power types, and mounting options.

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 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 the factory floor!
Hardened Media Converter Switches are for dusty or dirty environments with temperatures that range between -13 and +140º F (-25 to +60º 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 daisychain 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 wallmounted, and one set mounted in the end next to the media ports for easy viewing when units are in a rackmount tray.

Choose AC or DC power.
Hardened Media Converter Switches have the power options to support harsh environments, too. Models with AC power supplies support 100–240-VAC power. The power supplies with recessed IEC power connectors work with any IEC standard power cord, making them adaptable to most international locations.

DC-powered units have internal screw terminals for connecting DC power in addition to an AC power jack. Because these models have dual power connections, you can use them simultaneously with both your DC power supply and an AC power adapter (sold separately) to provide redundant power input.

Mounting options galore.
Media Converter Switches fit in where you need them. They come with neat, removable rubber feet so you can use them as standalone units. Or you can easily panelmount them with the included brackets and screws.

For use with DIN rails, order the optional DIN Rail Mounting Bracket. This handy bracket features springmounting, enabling you to easily pop your Media Converter Switches on and off the DIN rail without using a screwdriver or tightening set screws. DIN-rail-ready Media Converter Switches are also available.

For rackmounting in a central location, choose the optional Rackmount Tray or Powered Rackmount Tray. The powered tray provides power for up to eight units.
