Black Box LMC270A-MM-ST Transceiver/Media Converter

Keep critical networks connected in demanding industrial environments where standard networking equipment cannot withstand extreme conditions. These hardened Fast Ethernet media converters extend 10/100 Mbps copper Ethernet over fiber, helping organizations increase network reliability, overcome distance limitations, and maintain connectivity in manufacturing facilities, utilities, transportation systems, security networks, energy sites, and outdoor installations.

Designed for harsh environments, these industrial-grade converters enable copper-to-fiber migration while delivering the durability needed for challenging operating conditions. Multimode models provide cost-effective fiber connectivity for distances up to 2 km, making them ideal for factory floors, warehouses, and large facilities. Single-mode models extend network traffic up to 20 km, enabling dependable communication between remote buildings, substations, industrial control systems, and distributed infrastructure.

Fiber connectivity improves network stability by reducing exposure to electromagnetic interference, electrical noise, and grounding issues commonly found in industrial settings. Available with either SC or ST fiber interfaces, these converters provide flexible deployment options to match existing fiber infrastructure while supporting long-term network expansion.

Whether extending surveillance systems, industrial automation networks, remote monitoring equipment, or facility-wide Ethernet connectivity, these rugged media converters help deliver greater uptime, improved reliability, and expanded network reach where dependable communications are essential.
