Product Features
Technical Overview
This media converter switch employs Fast Ethernet technology to handle network traffic at 100 Mbps, compatible with both 10/100Base-TX over twisted pair and 100Base-X over fiber. The SC port uses multimode fiber with a 1300 nm wavelength, optimized for short to medium-range applications. Conversion between media types is seamless, maintaining signal integrity across the supported 2 km distance, which reduces latency and signal loss compared to longer copper runs.
The device features a hardened design to withstand temperature variations and harsh conditions, ensuring stable performance in challenging environments. Its small footprint—3.50 inches high, 3 inches wide, and 1 inch deep—makes it easy to deploy in space-constrained areas. Weighing approximately 4.80 ounces, it is lightweight yet robust, with rack-mountable options for organized installations in data centers or network closets.
Key Product Advantages
The LBH100A-H-SC excels in extending network reach by converting copper Ethernet to fiber optic, overcoming distance limitations of traditional cabling. Its hardened construction provides reliability in non-climate-controlled settings, such as warehouses, manufacturing floors, or outdoor enclosures, where temperature fluctuations are common. This durability minimizes downtime and maintenance costs, offering a cost-effective solution for robust network infrastructure.
Distance Extension
Supports fiber runs up to 2 km, far exceeding the 100-meter limit of standard copper Ethernet, enabling connectivity across large facilities or between buildings.
- Reduces signal degradation
- Eliminates need for repeaters
Flexible Deployment
The external and rack-mountable form factor allows installation versatility, from desktop use to integrated rack systems, without internal hardware modifications.
- Easy external setup
- Saves rack space
Deployment / Use Cases
This media converter is ideal for scenarios where network segments need to span longer distances or traverse electrically noisy environments. In industrial settings, it connects machinery on the factory floor to central control systems via fiber, ensuring data integrity despite electromagnetic interference. For educational or corporate campuses, it links buildings over fiber backbones, extending LANs without sacrificing speed or reliability.
In telecommunications or ISP deployments, the converter integrates into existing copper networks to add fiber uplinks, enhancing bandwidth and future-proofing infrastructure. Its TAA compliance makes it suitable for government contracts or projects requiring adherence to trade agreements, while the 3-year warranty provides peace of mind for critical installations. The compact size also benefits retrofits in tight spaces, such as network cabinets or outdoor junction boxes.
Industrial Networking
Connects PLCs, sensors, and HMIs across manufacturing plants using fiber to resist interference and extend reach beyond copper limits.
Campus Connectivity
Links multiple buildings in a school or business park via fiber backbones, supporting high-speed data transfer for VoIP, video, and data services.
Physical Profile
The converter has a slim, rectangular design measuring 3.50 inches in height, 3 inches in width, and 1 inch in depth, with a weight of about 4.80 ounces. This compact form factor facilitates easy placement on desktops, shelves, or within rack systems using optional mounting hardware. The hardened casing protects internal components from environmental stressors, ensuring consistent operation in varied temperatures and conditions.
