Industrial VHF 136-174MHz Fiber DAS System with IP65 Remote Unit
Built Tough for the World's Hardest Jobs

Petrochemical refineries, open-pit mines, steel mills, offshore platforms, and remote power stations—these environments push communications equipment to its absolute limits. Ambient temperatures swing from arctic cold to desert heat, corrosive chemicals fill the air, heavy machinery generates constant vibration, and high-voltage equipment produces electromagnetic interference that can cripple conventional RF systems. Our Industrial VHF Fiber DAS System is engineered from the ground up for these unforgiving conditions, delivering reliable communications when and where it matters most.

The remote unit's IP65-rated enclosure provides complete protection against dust ingress and low-pressure water jets from any direction, while convection cooling eliminates the fans and filters that are the most common failure points in industrial electronics. Fiber optic cabling is inherently immune to electromagnetic interference, ensuring clean signal transport through electrically noisy environments where copper-based systems would fail. With wall or pole mounting options and optional LTE modem for remote monitoring at network-isolated sites, the system adapts to the unique physical constraints of any industrial deployment.

Industrial-Rated Durability
  • IP65 dust-tight and water-jet-resistant remote unit enclosure for harsh duty
  • Fanless convection cooling eliminates the most common industrial failure point
  • EMI-immune fiber backbone operates reliably near high-voltage and heavy machinery
  • Wide temperature operation (-10 to +55°C) handles arctic to tropical extremes
  • Optional LTE modem enables remote monitoring at off-grid and isolated sites
  • Wall or pole mounting with 24kg rugged construction for stable outdoor installation
