Rugged industrial media converter bridges 10/100 Mbps copper to fiber for harsh environments

  • Rugged industrial case protects conversion circuitry in harsh environments
  • Converts legacy 10/100-Mbps copper segments to fiber backbone links
  • Supports optical fiber for durable performance with minimal signal loss
  • Rail-mountable design enables convenient installation in factories and power plants
  • Expand network connections by attaching multiple transceiver/media converter devices

Industrial Media Converter

The Black Box LMC270A-MM-ST is a hardened mini industrial media converter designed for unmanaged conversion between legacy copper and fiber segments. It targets engineers and technicians maintaining networks in power plants, mining operations, and military sites where temperature extremes and contaminants threaten standard equipment. The rugged 2-port device handles 10- or 100-Mbps twisted pair connections alongside optical fiber backbones.

Industrial Case and Rail Mounting

An industrial-strength case protects the internal circuitry from harsh environmental conditions encountered in factory applications. The rail-mountable design allows convenient installation onto standard DIN rails inside cabinets or enclosures. Two transceiver or media converter units can be attached together to expand the number of devices connected to an existing network infrastructure.

Fiber Connectivity Benefits

Support for optical fiber cable enables durable performance with minimal signal loss over greater distances compared to copper alone. The converter delivers up to 100Mbps data transfer rates over twisted pair using 10/100Base-TX technology. This combination extends reliable network reach in demanding industrial settings without requiring managed switching hardware.
