Product Features
Technical Overview
This media converter operates at an 850 nm wavelength over multi-mode fiber, compatible with core/cladding specifications including 9/125 µm, 100/140 µm, 8.3/125 µm, 8.7/125 µm, and 10/125 µm. It achieves a maximum supported distance of 0.50 km (0.31 mile), making it suitable for campus, building, or floor-level fiber extensions where copper limitations would otherwise restrict reach.
The device features a simple two-port design with one RJ-45 port for twisted-pair copper connections and one Duplex SC port for fiber optic cabling. This configuration ensures dedicated, full-duplex conversion without internal switching complexity, delivering consistent 1000 Mbps throughput in both directions. Power is supplied via an included 5-VDC AC adapter with a barrel connector, supporting continuous operation in standard office environments.
Key Product Advantages
The LGC211A media converter eliminates distance and interference constraints of copper cabling by leveraging fiber optic reliability and noise immunity. Its plug-and-play operation requires no configuration, reducing deployment time and technical overhead for network expansions or retrofits.
Fiber Compatibility
Supports a wide range of multi-mode fiber core/cladding sizes, ensuring compatibility with common fiber plant installations without requiring specialized cables.

User Manual
FAQ
What does this media converter do?
The Black Box LGC211A converts Gigabit Ethernet signals between standard RJ45 copper ports and Duplex SC multi-mode fiber ports. It allows you to extend network connections beyond the typical 100-meter copper limit by using fiber optic cabling, supporting distances up to 0.50 km while maintaining full 1000 Mbps throughput.
What type of fiber is compatible with this converter?
This converter works with multi-mode fiber optic cables operating at an 850 nm wavelength. It supports various core/cladding specifications, including 9/125 µm, 100/140 µm, 8.3/125 µm, 8.7/125 µm, and 10/125 µm, making it compatible with common multi-mode installations in enterprise and campus networks.
