IP68 Industrial Splice Enclosures are heavy duty protective cases designed to house and safeguard fibre optic splices in the most extreme environments. These units provide a hermetically sealed environment that prevents the entry of dust, moisture, and pressurized water. At Fibre Systems, we engineer these enclosures to ensure that your critical data links remain operational even when submerged in flooded pits or exposed to the high humidity of deep underground mines.
The Constant Threat of Water Ingress
In the world of underground mining and outdoor telecommunications, water is a relentless enemy. It is not just about a bit of dampness; it is about high pressure groundwater, seasonal flooding, and the constant drip of acidic mine water. Standard plastic enclosures might hold up for a while, but eventually, the seals fail. Once Water Ingress begins, the delicate fibre splices inside are compromised, leading to immediate signal failure and costly network downtime.
When you install IP68 Industrial Splice Enclosures, you are placing a permanent barrier between your network and the elements. These are not mere “water resistant” boxes; they are designed for total immersion. In a flooded outdoor telco pit, a standard enclosure becomes a bucket that holds water against your equipment. Our Fibre Systems enclosures are built to stay dry on the inside, no matter how much pressure is pushing from the outside.
Why Hermetically Sealed Units are Non Negotiable
Underground mining environments are uniquely hostile. Between the high vibration of heavy machinery and the chemical profile of groundwater, a standard seal simply will not last. This is where Hermetically Sealed technology becomes a necessity. A hermetic seal ensures that the air inside the enclosure remains constant, preventing the internal condensation that often leads to “fibre rot” or the slow degradation of optical glass.
Our IP68 Industrial Splice Enclosures utilize advanced gasket technology and mechanical compression to create an airtight environment. At Fibre Systems, we have seen countless network failures that were blamed on “bad fibre,” only to discover that the culprit was a cheap enclosure that allowed humid air to enter and expand. By choosing a high grade enclosure, you are protecting the Network Integrity of your entire site from the microscopic level up.
Engineering for the Deep Mine Profile
The deeper you go in an underground mine, the higher the atmospheric pressure and temperature. These conditions test the limits of industrial hardware. Many enclosures that claim an IP rating are only tested in shallow water for short periods. However, in a real world mining application, an enclosure might be submerged under several meters of water for months.
We build our IP68 Industrial Splice Enclosures to exceed standard testing. We use reinforced polymers and corrosion resistant hardware that can withstand the weight of water and the chemical assault of saline mist. Whether you are operating in the red dust of Western Australia or the deep, humid shafts of a coal mine, these enclosures provide the physical armor your data needs to keep flowing without interruption.
Technical Comparison: Standard vs. IP68 Enclosures
| Feature | Standard Telco Enclosure | IP68 Industrial Splice Enclosures |
| Ingress Protection | IP54 or IP65 (Splash proof) | IP68 (Submersible/Dust tight) |
| Seal Type | Foam or Simple Rubber | High Grade Viton/Silicon Gaskets |
| Pressure Resistance | Low (Internal air gaps) | High (Hermetically Sealed) |
| Material Durability | Standard Plastic | UV Stabilized / Chemical Resistant |
| Application | Indoor or Managed Pits | Underground Mining / Flooded Areas |
Maintaining Network Integrity in Outdoor Pits
Telecommunications providers often face the “invisible” problem of stagnant water in outdoor pits. These pits are prone to flooding during heavy rains, and the water can sit for weeks. If your splices are not protected by IP68 Industrial Splice Enclosures, the moisture will eventually bridge the gap in your connector housings.
By standardizing your outdoor infrastructure with Fibre Systems hardware, you eliminate the risk of seasonal outages. You no longer have to send technicians out after every storm to pump out pits and dry out connectors. The peace of mind that comes with knowing your splices are dry, even in a submerged pit, is invaluable for maintaining consistent service levels and avoiding customer frustration.
A Step by Step Guide to a Perfect Seal
- Cable Preparation: Ensure the cable outer jacket is clean and free of grease before entering the enclosure.
- Grommet Selection: Match the cable diameter precisely to the enclosure grommet to ensure a tight fit.
- Internal Management: Organize your splices neatly in the trays to avoid any pressure on the glass.
- Seal Inspection: Always check the O-ring for nicks or debris before closing the lid.
- Compression: Tighten the bolts or latches to the specified torque to engage the hermetic seal.
- Vacuum Testing: For mission critical links, perform a pressure test to confirm the enclosure is Hermetically Sealed.
The Financial Logic of Hardened Protection
It is easy to look at the price of a standard enclosure and wonder why you should pay more for a ruggedized version. But in a remote industrial setting, the price of the hardware is the smallest part of the equation. The real cost lies in the five hours of lost production because a flooded pit killed the telemetry to your drill rigs.
Investing in IP68 Industrial Splice Enclosures is a strategic decision to minimize risk. It is an insurance policy against the unpredictable nature of industrial environments. At Fibre Systems, we focus on providing hardware that lasts longer than the project itself. We have units in the field that have survived multiple floods without a single drop of water reaching the internal fibre core.
Frequently Asked Questions
Can these enclosures handle acidic mine water?
Yes. Our IP68 Industrial Splice Enclosures are made from specialized engineered plastics that are resistant to a wide range of industrial chemicals and acidic groundwater commonly found in Underground Mining.
How often do the seals need to be replaced?
Our high grade gaskets are designed for long term deployment. However, we recommend inspecting the seal every time the enclosure is opened for maintenance to ensure it remains debris free and intact.
Are these units suitable for direct burial?
While they are primarily designed for pits and underground shafts, the high structural integrity of our IP68 Industrial Splice Enclosures makes them suitable for many direct burial scenarios where water pressure is a concern.
Built for the Worst to Provide the Best
The industrial world does not stop for a storm or a flood. Your data network shouldn’t either. IP68 Industrial Splice Enclosures are the essential foundation for any resilient infrastructure project. They allow engineers to deploy fibre in places once thought impossible, from the bottom of deep mines to the most flood prone coastal pits.
Fibre Systems is proud to be a leading provider of these hardened solutions across Australia. We continue to innovate and test our hardware against the most aggressive environmental conditions to ensure that when your mission is on the line, your connection remains rock solid. Stop risking your Network Integrity on “good enough” solutions and upgrade to the industry standard for environmental protection.
