Applications — Where the Product Is Used
1 FTTH & Access Networks
A 7-way bundle fits perfectly into the fiber-to-the-home network, particularly in scenarios involving huge real estate projects, master communities, and new residential areas. The microduct can be dedicated to:
- Various buildings
- Different telecom operators
- Possible future routes
- More drops without new digging
2 Smart City Infrastructure
The cities in KSA, UAE, and Qatar are transforming and digital infrastructure needs multiple fiber pathways for:
- CCTV
- Traffic controls
- IoT installations
- Street lighting
- 5G small cells
All services get a single trench for them with a 7-way 25/20 mm microduct bundle.
3 Air-Blown Fiber Systems
Ducts receive the low-friction inner surface and are thus very suitable for the long-distance jetting/blowing of fibers with minimal stress on the cables.
4 Oil & Gas Industrial Networks
Secure and segregated fiber routes for:
- SCADA systems
- Monitoring networks
- Backbone connectivity
- are the main reason for Industrial zones, refineries, and plants to install HDPE microducts with chemical resistance and long life.
5 Data Centers & Campus Backbones
The 25/20 size is the specification of the inner diameter that is large enough for microcables of the highest fiber density and that the networks of high capacity are still available for future use.
6 Direct Burial Trenching
25/20 ducts with a thick wall have sufficient strength to be directly buried in soil without the need for any other protective conduit.
How It Is Used (Step-by-Step)
1 Route Planning
Engineers map which microduct carries which service. Color coding makes this easier.
2 Trenching
Depending on the project scale, contractors use:
Open-cut trenches
Micro-trenching
HDD (Horizontal Directional Drilling)
Existing duct banks
3 Laying the Microduct Bundle
Reels of 300–1000 meters are laid into the trench. The hexagonal bundle resists deformation and keeps ducts organized.
4 Backfilling
Contractor places sand bedding, protective tile, warning tape and final backfill.
5 Blowing the Fiber
Once ducts are ready:
Air-blown fiber machines jet microcables into each microduct
Lubricants may be used depending on distance
Blowing distances can range from 500 m to several kilometers depending on conditions
6 Termination
At manholes or handholes, ducts are terminated into:
Distribution boxes
Splice closures
Fiber cabinets
7 Testing
Final steps include:
Fiber continuity testing
Air pressure tests
Verification of duct labeling
Advantages of Microduct 7-Way Hexagonal 25/20 mm
1 High Capacity in One Trench
The use of seven large microducts not only doubles but also triples the existing capacity of the trench, since the fiber routes are made independently and without any trench expanding.
2 Future-Proof Fiber Expansion
In a couple of years, the extra ducts will be ready to use without needing to retrench.
3 Ideal for Blown Fiber
The 20 mm inner diameter allows a hassle-free jetting of medium to large microcables in the following way:
- Backbone links
- Corporate fiber lines
- Long-distance FEWA/DEWA routes
4 Suitable for Gulf Climate
The trench material is HDPE which is extremely resistant to the scorching sun, UV rays and sand erosion.
5 Excellent Mechanical Strength
Very thick walls like mountain peaks repel all kinds of pressures and crushing, thus being safe for direct burial.
6 Reduced Installation Cost
The total installation price of one 7-way bundle is far less than that of seven separate single ducts installed.
7 Compatible with Many Cable Types
These include:
- Mini fiber cables
- Microcables
- Nano fiber
- Multi-core high-density fibers
Limitations and Considerations
1 Larger Duct Means Larger Bend Radius
25 mm OD ducts require careful planning around corners.
2 Blowing Distances Depend on Conditions
Long runs may require intermediate blowing points or additional lubricant.
3 Slightly Higher Material Cost
Thicker and larger-sized microducts are more expensive but reduce long-term excavation costs.
4 Requires Skilled Installers for Jetting
Air-blown fiber requires trained personnel for best performance.
Detailed Buyer’s Guide for KSA & Gulf Contractors
1. Start by determining the project type.
For FTTH (Fiber to the Home), a duct with a 16 mm internal diameter (ID) would suffice; for backbone and data center routes, however, a duct with a 20 mm ID would be the best choice.
2. Selecting the wall thickness
- Wall thickness for direct-buried installation: thick wall
- Wall thickness for conduits or duct banks: thin wall
3. Tracer wire specification only if needed
If you want to be able to pinpoint its exact location in the future, then opt for:
- Copper tracer wire
- Metallic tape
- RFID markers
4. Inner surface type verification
For long blowing runs, choose ribbed/low-friction liners.
5. Operating temperature check
Ensure that the ducts can handle the maximum Gulf temperatures (up to +60°C).
6. Reel length confirmation
Using longer reels will result in fewer couplers and faster installation.
7. Datasheets and certifications requests
Coming from the suppliers, ask for:
- Reports of material tests
- Certification of UV resistance
- Rating for direct burial
- Results of pressure/crush tests
Lifecycle & Maintenance
1. Minimal Maintenance
Microducts are underground and maintenance is almost non-existent.
2. Inspection after Civil Works
Every road cutting or construction near the site should activate:
- Duct trace checking
- Pressure testing if necessary
3. Easy Fiber Upgrading
Future upgrades will only require blowing new cable, not digging.
4. Long Life Service
Under ground conditions, HDPE microducts usually last more than 50 years.
