Black Box Gigabit Industrial Media Converter Multimode SC

The Black Box LGC281A is a gigabit industrial media converter that lets you extend an Ethernet network over multimode fiber without redesigning your entire infrastructure. It accepts a 10, 100, or 1000 Mbps copper connection and converts it to 1000Base-X fiber through an SC port, making it a straightforward drop-in whenever you need to bridge long distances or electrically noisy areas.

Engineered for demanding locations, the unit operates from -40 to 158 degrees Fahrenheit and sits inside an IP-30 metal housing that stands up to dust, vibration, and temperature swings common in factory floors, traffic control cabinets, or outdoor enclosures. Dual 12 to 48 VDC power inputs add redundancy so the link stays up even if one supply fails.

Network administrators who push high-bandwidth traffic will appreciate support for jumbo frames up to 10,240 bytes, which reduces overhead on large data transfers such as industrial vision streams or aggregated sensor data. Store-and-forward switching ensures each packet is checked before it moves on, protecting the rest of the network from corrupted frames.

Installation is flexible. Clip it to a DIN rail inside a control panel or fasten it to a wall plate in a maintenance room. Once mounted, connect multimode fiber up to 550 meters long at 850 nm, plug in the copper side, and the link is live—no complex configuration required. Whether you need to link PLCs across a plant, backhaul IP cameras around a warehouse, or provide a resilient connection to a remote kiosk, the LGC281A delivers gigabit performance with industrial-grade reliability.
