GRP Armoured Rodent Proof Loose Tube Blue Nylon Jacket Fibre Optic Cable – OM3/OM4
*** Please call (03) 9761 7925 for pricing ***
The RapidConnect® G-Series GRP Armoured Fibre Optic Cable provides combined rodent and termite protection within a non-metallic loose tube cable construction.
The cable uses GRP rods as the rodent-protection layer, while a Blue Nylon inner jacket provides termite protection. A durable Black PE outer jacket completes the external protective system.
Because the GRP armour contains no conductive metal, the G-Series remains an all-dielectric cable. Therefore, it provides strong physical protection without introducing steel armour, corrosion risk, or the electrical considerations commonly associated with metallic armoured cable.
Available from fibreSales, the G-Series suits demanding underground telecommunications, industrial, utility, mining, transport, campus and infrastructure networks where biological attack could threaten long-term fibre reliability.
Rodents and termites create different threats to underground fibre cable.
Rodents can physically gnaw through conventional cable jackets and damage buffer tubes or fibres. Termites create a separate biological risk and may attack polymeric materials in underground environments.
The RapidConnect G-Series addresses both risks through a layered protection system.
GRP rods provide the physical rodent barrier.
Blue Nylon provides the termite barrier.
Black PE provides the external environmental and mechanical jacket.
This combination gives network designers a purpose-built protected cable rather than relying on one jacket material to manage every threat.
From outside to inside, the RapidConnect G-Series uses:
Each layer performs a different function.
This layered design allows the cable to address external mechanical exposure, rodents, termites, moisture and fibre protection within one coordinated cable structure.
The Black PE jacket forms the external surface of the G-Series.
It protects the GRP armour and internal cable components during:
Polyethylene offers a useful combination of toughness, flexibility and moisture resistance for outdoor telecommunications cable.
However, the Black PE jacket does not provide the primary rodent or termite protection.
Instead, the specialised GRP and Blue Nylon layers sit beneath the PE sheath.
The G-Series uses Glass Reinforced Plastic rods beneath the outer PE jacket.
These rods form a hard physical barrier around the protected inner cable.
If a rodent damages the Black PE sheath, the GRP armour sits between the animal and the inner fibre cable.
Therefore, the protection does not depend only on the outer jacket remaining untouched.
The GRP rods provide:
This makes GRP particularly useful where a project requires armoured protection but the designer wants to avoid metallic cable components.
Beneath the GRP armour, the G-Series incorporates a Blue Nylon inner jacket.
This layer provides dedicated termite protection around the internal loose tube cable.
The construction creates two distinct biological protection systems:
The contrasting blue jacket also helps technicians identify the protected inner cable during cable preparation.
Traditional armoured fibre cable often uses steel tape, corrugated steel or steel wire.
These constructions can provide excellent mechanical protection, but they also introduce metal into the cable.
Depending on the installation, metallic armour may introduce additional considerations involving:
RapidConnect G-Series uses non-metallic GRP armour instead.
As a result, the cable retains an all-dielectric construction while still providing a substantial physical protective layer.
Choose G-Series when you need rodent and termite protection but want to avoid conductive metallic armour.
This can prove particularly valuable around electrical infrastructure, industrial environments, utilities and other locations where electrical isolation forms part of the cable-selection process.
GRP does not rust like steel.
Therefore, the G-Series can provide an advantage in wet, humid or corrosive environments where damaged metallic armour could degrade over time.
Potential environments include:
The Black PE jacket still protects the cable externally. However, the GRP armour itself does not suffer from conventional steel corrosion.
Underground ducts and pits do not always remain dry.
Groundwater, condensation, flooding and damaged seals can introduce moisture into cable pathways.
RapidConnect G-Series uses dry water-blocking technology to help restrict longitudinal water movement if moisture reaches the internal cable structure.
Dry water blocking can also make cable preparation cleaner than traditional fully gel-flooded cable designs.
Benefits include:
However, installers should still seal cable ends and enclosure entries correctly.
Water blocking supports moisture management; it does not replace good installation practice.
The G-Series uses loose tube technology to protect the optical fibres from external mechanical and environmental effects.
In a loose tube cable, the fibres sit within protective buffer tubes rather than directly against the surrounding cable layers.
This helps isolate the fibres from:
Loose tube construction also supports a range of fibre counts and Singlemode or multimode configurations.
RapidConnect G-Series suits infrastructure where rodents, termites or both present a credible long-term risk.
Typical applications include:
Long telecommunications routes can pass through pits, conduits and locations that are difficult to access after installation.
A single damaged cable may affect many network services.
Therefore, physical biological protection can provide significant value on backbone and inter-building routes where repairs would require civil work, fault location and emergency restoration.
Industrial facilities can provide ideal pathways for rodents through service corridors, plant rooms and protected infrastructure.
At the same time, fibre networks may support:
The G-Series combines physical protection with non-conductive armour, making it well suited to demanding industrial environments.
Mining sites often combine large geographic areas, demanding environments and difficult maintenance access.
Fibre links may support operational technology, network communications, monitoring and production systems.
Where biological attack presents a risk, G-Series provides a non-metallic alternative to steel-armoured cable.
GRP armour can provide particular advantages near electrical infrastructure.
Because GRP does not conduct electricity, the G-Series avoids introducing a metallic armour path into the fibre route.
Potential applications include:
The complete installation must still meet applicable standards and project requirements.
Schools, hospitals, universities, commercial campuses and government sites often connect buildings with underground fibre links.
Landscaped areas, pits and older conduits may expose these networks to rodents or termites.
Therefore, the G-Series provides an option where cable-level biological protection forms part of the network design.
GRP and steel armour solve similar problems in different ways.
| Feature | GRP Armour | Steel Armour |
|---|---|---|
| Rodent protection | Yes | Yes |
| Metallic | No | Yes |
| Conductive | No | Yes |
| Corrosion risk | Low | Possible |
| Bonding considerations | Reduced | May apply |
| Earthing considerations | Reduced | May apply |
| Electrical isolation | Excellent | Lower |
| Weight | Often lower | Often higher |
| Flexibility | Often better | Often stiffer |
Steel armour remains appropriate for many installations.
However, GRP can provide a better solution where the project needs mechanical protection without introducing conductive metal.
A standard loose tube cable can provide excellent outdoor performance.
However, it may not include dedicated rodent or termite protection.
The G-Series adds these specialised layers:
Therefore, choose standard loose tube cable when biological protection does not drive the specification.
Choose G-Series when rodent and termite exposure justify a more protected construction.
Some outdoor cables provide termite protection without rodent armour.
G-Series goes further by combining both protection types.
Choose a standard termite-protected cable when termite resistance is the primary concern.
Choose RapidConnect G-Series when the project requires:
Rodent protection + termite protection + non-metallic armour.
Before ordering, consider the complete installation.
Determine whether the route faces:
Previous cable damage, pest activity and site conditions can help identify the actual exposure.
Select the correct fibre category for the network.
Options may include:
Your transmission distance, active equipment and future network requirements should guide the selection.
Allow for:
Installing additional fibre capacity during the original project usually costs less than adding another cable later.
Confirm whether the cable will run through:
Do not assume one cable construction suits every underground installation method.
Review:
The final values should come from the exact supplied configuration.
Consider:
Correct installation protects every layer of the cable.
Before installation, confirm:
During cable preparation, technicians should take particular care when removing the Black PE outer jacket and GRP rods.
The Blue Nylon layer underneath provides termite protection, so installers should avoid damaging it unnecessarily.
Professional fibre installation requires optical testing before commissioning.
Depending on the project, testing may include:
fibreSales supplies OTDRs, Fusion Splicers, Fibre Cleaning Products and Fibre Inspection Microscopes for professional installation and commissioning work.
Rodent or termite damage can turn a relatively small cable breach into a major infrastructure problem.
Once the outer jacket becomes damaged, the network may face:
For remote or difficult-to-access routes, these costs can far exceed the initial difference between standard cable and a purpose-built protected cable.
Cable price represents only one part of an underground fibre project.
Civil work, labour, pits, conduits, splicing, testing and network downtime often cost substantially more than the cable itself.
Therefore, choosing cable only on initial metre price can create a false economy.
