H3RO: Fast and Simple Downtime Recovery

Ampcontrol was engaged by an underground gold and copper mine in Western NSW, to provide fibre optics quickly after an existing communications cable was severed.

About the project

An existing fibre optic cable was severed at the underground gold and copper mine. This optical distribution network (ODN) was vital for mining operations. Production could not be started without dependable and reliable communication with seismic sensors.

Ampcontrol’s H3RO, harsh environment reticulated fibre optic solution, was deployed from an existing FOBOT panel for a distance over 1km along the roof, through a number of vertical drops and into another existing FOBOT enclosure.

H3RO’s plug and play cables and modular components made it the ideal choice for the fast deployment of cabling for this work. The IP68 connectors and bulkheads allowed a neat, maintainable solution that integrated seamlessly with off-the-shelf IP68 bulkheads and pigtails to match the existing patch panels.

Due to the modular installation and low loss connectors, network expansion and recovery from similar incidents in the future is now hassle free.

The entire cable run consists of a quantity of four 260m 12 core H3RO cables, making swapping any section out easy, rather than replacing the entire run or requiring expensive and time consuming fibre field splicing in the mines harsh environment.

H3RO components are manufactured in state-of-the-art facilities, all items are tested and shipped with quality reports. This offers a more cost effective, reliable and risk free solution to field splicing in an underground mine where constraints such as time, darkness and the dirty working environment all affect the quality of the job.


H3RO’s plug and play functionality and modular components enabled installation to be completed quickly by site staff, as opposed to specialist fibre optic technicians. The 260m cables on mobile reels allowed fast deployment from vehicles and fit for purpose bulkheads to pigtails allowed seamless integration with existing enclosures.

By using H3RO, expensive fibre termination equipment and specialist staff or training is no longer required to maintain the system.

H3RO’s modular components and future proof design enables cost effective and quick and easy duplication or extension as ODN requirements evolve.

H3RO Fibre Optic Backbone for a Coal Mine

Ampcontrol was engaged by an underground coal mine to provide a fibre optic backbone for communication with underground mining equipment.

About the project

Ampcontrol were asked to include network connectivity as part of the supply of high voltage, electrical hardware to the underground mine. The mine required easy to deploy fibre optic hardware, for integration with new and existing equipment including third party equipment and patch panels.

Utilising H3RO, Ampcontrol’s harsh environment reticulated fibre optic solution, monitoring and control of underground equipment was achieved by connecting from an existing FOBOT patch panel
throughout the mine.

H3RO’s plug and play components made it the ideal choice for hassle free deployment of cabling for this work. The IP68 connectors and bulkheads allowed a neat, maintainable solution that integrated seamlessly using off-the-shelf IP68 bulkheads and pigtails to match existing third party equipment and patch panels.

The H3RO solution utilises common components which allowed consolidation of spares and standard deployment procedures. Extending or swapping network sections with the plug and play infrastructure is an easier and more reliable process than the traditional method of splicing and terminating fibre optics in the field.


H3RO’s plug and play functionality and modular, interchangeable components enabled quick installation of the network by site staff, without the need for specialist fibre optic technicians. The result is a high quality, low loss dynamic network.

The H3RO cabling and components are fit for purpose for harsh environments and are priced to be replaced rather than repaired and are supplied pre-terminated with IP68 connectors for quick installation to reduce downtime. This provides immediate benefits if there is network interruption due to fibre cable damage as the BOTS (Break Out Terminals) and cabling can be easily and quickly replaced.

Compared with traditional fibre optic solutions, the installation was more cost and time effective. Fast cable deployment from a vehicle was possible with the provision of standard length cables on mobile reels and fit for purpose bulkheads to pigtails allowed seamless integration with existing enclosures. As the network expands, the system can adapt to support future requirements.

H3RO in an Underground Copper Mine

Fibre optic cable was required at the underground copper mine to monitor and manage automated mining equipment. Ampcontrol’s H3RO; harsh environment reticulated fibre optic solution, was deployed from the telecommunications hut on the surface, down a catenary wire through the existing open cut mine and into the new underground mine.

H3RO’s robust IP68 Bots (Break-Out Terminals) and UV protected cables made it the ideal choice for both the surface and underground components of the project. The H3RO fibre was reticulated down the mine with the H3RO Bots positioned where fibre cores would be required now and in the future.

Services utilising this fibre optic network include phones, load scanning, seismic sensors and sub-station monitoring. The H3RO system was terminated into the autonomous miner, allowing remote operation.
The modular system allows easy expansion as the mine progresses and agility in accessing the fibre network anywhere between the face and surface as requirements evolve.


H3RO’s plug and play functionality and modular components enabled this installation to be undertaken by site staff, as opposed to specialist fibre optic technicians. This saved the remote site considerable time and money.

Ampcontrol then undertook a site fibre optic audit and OTDR (Optical Time-Domain Reflectometer) testing to verify the install before the new underground machines were commissioned.

H3RO’s modular components and future proof design enables quick and easy duplication or extension as required, ensuring the system can be expanded and modified as the mine advances.

Future network extensions will be completed and tested by site labour. An OTDR, training and connector cleaning and inspection kit were supplied as part of the total package.

Since commissioning the H3RO system has performed reliably, been integrated easily with additional 3rd party equipment.
