Deployment / Use Cases
This media converter is ideal for extending network segments between buildings, connecting remote devices, or integrating fiber backbones into existing copper networks. Its hardened design makes it suitable for industrial facilities, outdoor installations, and environments with temperature extremes.
Common applications include connecting security cameras across large campuses, linking network equipment in manufacturing plants, and extending network access to remote kiosks or signage. The converter can also serve as a cost-effective solution for gradually migrating from copper to fiber infrastructure.
Industrial Network Extension
Connect PLCs, sensors, and control systems across factory floors or outdoor areas using fiber for noise immunity and distance.
Campus Connectivity
Link separate buildings with fiber for high-speed data transfer while maintaining compatibility with existing copper devices.
Physical Profile
Measuring 3.5" (88.90 mm) high, 3" (76.20 mm) wide, and 1" (25.40 mm) deep, the converter has a compact footprint that fits easily in racks or on desktops. The lightweight design at 4.80 oz (136.08 g) simplifies handling and mounting.
The physical profile is practical for deployment planning because the dimensions and weight are clearly defined: 3.50" (88.90 mm), 3" (76.20 mm), 1" (25.40 mm), 4.80 oz (136.08 g). This helps confirm rack, shelf, desk, or cabinet fit before installation.

User Manual
FAQ
What does this media converter actually do?
The Black Box LBH100A-H-ST converts Fast Ethernet signals between copper and fiber media. It takes data from two 10/100 Mbps RJ-45 copper ports and converts it for transmission through one ST multimode fiber port, or vice versa, allowing network extension up to 2 kilometers.
What type of fiber cable is compatible with this converter?
This converter uses multi-mode fiber with ST duplex connectors. It operates at a 1300 nm wavelength, which is standard for many multi-mode fiber installations. Ensure your fiber patch cables have ST connectors and match the multi-mode specification.
How far can this converter extend my network?
The maximum supported distance is 2 kilometers (approximately 1.24 miles) when using multi-mode fiber. This is significantly longer than the 100-meter limit of standard copper Ethernet, making it ideal for connecting buildings or remote equipment.
Can this converter be rack-mounted?
Yes, the LBH100A-H-ST supports both external desktop placement and rack-mount installation. Its compact dimensions of 3.5" H × 3" W × 1" D allow it to fit in standard rack enclosures alongside other networking equipment.
What does 'hardened' mean for this device?
Hardened indicates the converter is designed to operate reliably across a wide temperature range, making it suitable for industrial or outdoor environments where temperature fluctuations might affect standard equipment. It maintains stable performance in harsh conditions.
Is this converter TAA compliant?
Yes, the Black Box LBH100A-H-ST is TAA (Trade Agreements Act) compliant and manufactured in the United States. This makes it eligible for government and institutional procurement where TAA compliance is required.
