Operations are organized with refined industrial controls and sensors for safety and operations effectiveness. The precedence for mining submission is network reliability between the distributed devices

Our housings are also waterproof, dust-tight and corrosion resistant which improves reliability to perilous surroundings while securing a solid connection

With mining footprints in Mozambique and SA surrounds, our products scientifically increase the network connectivity.

  • Thinner – Optical fibres can be drawn to smaller diameters than copper wire.
  • Higher carrying capacity – Because optical fibres are thinner than copper wires, more fibres can be bundled into a given-diameter cable than copper wires.
  • Less signal degradation – The loss of signal in optical fibre is less than in copper wire.
  • Light signals – Unlike electrical signals in copper wires, light signals from one fibre do not interfere with those of other fibres in the same cable. This means clearer phone conversations or TV reception.
  • Low power – Because signals in optical fibres degrade less, lower-power transmitters can be used instead of the high-voltage electrical transmitters needed for copper wires. Again, this saves your provider and you money.
  • Digital signals – Optical fibres are ideally suited for carrying digital information, which is especially useful in computer networks.
  • Non-flammable – Because no electricity is passed through optical fibres, there is no fire hazard.
  • Lightweight – An optical cable weighs less than a comparable copper wire cable. Fibre-optic cables take up less space in the ground.
  • Flexible – Because fibre optics are so flexible and can transmit and receive light, they are used in many flexible digital cameras.

OFT has worked on the following mining projects:

Goldfields South Deep
The Installation of cameras underground to monitor the levels of water at the plugs on levels 50, 58 and 60. Install IR lights to assist with low light conditions. Install field node to protocol equipment and house all supplies to the camera’s and lights. Connect these video streams to OTN on level 55 and make available on surface for recording, viewing and playback.

Harmony Doringfontein
The fibre backbone and OTN network will be used as the communication medium for the following systems:

  • Telephones
  • Seismic System
  • Fire detection system
  • Process Control
  • Power Control & Electrical Protection
  • Closed Circuit Television
  • Leaky Feeder Communication System
