Microduct 4 Way Square 25/20MM
MicroDuct 4 Way Square 25/20MM
HDPE PE100 Multi-Duct for FTTH, 5G & Smart City Networks (Gulf Telecom Standard)
Key Features & Benefits
✔ Four independent fiber pathways
It is possible to run multiple cables, create diversion routes, or use the fiber lines of the operator all inside the same building.
✔ 25/20MM huge capacity
The 20 mm bore is the one which enables longer blowing distances of the cable and higher fiber counts to the fullest.
✔ Square profile for high mechanical strength
The uniform load distribution prevents deformation in deep trenches, road crossings, and HDD routes.
✔ Made from PE100 HDPE (High-Density Polyethylene)
The first-class material grants the product with long life, flexibility, and resistance to adverse climate conditions.
✔ Smooth inner surface for better blowing performance
Friction is removed, the installation speed is boosted, and the required effort is minimized.
✔ Weather-resistant & UV stabilized
The black pipe is colored with UV-stable carbon black and bears blue stripes to indicate telecom installations.
✔ Perfect for Gulf climates
It can withstand the scorching heat, sand, and the environment of buried infrastructure.
✔ Compatible with micro-trenching, direct burial & duct-in-duct
Installation methods are many and flexible as needed in GCC cities.
✔ Long-term investment (50+ year design life)
No rust, little maintenance, and high reliability are the costs.

Material Construction — Why PE100 is Superior
Of all the common plastics used in telecom ducts, Polyethylene PE100 has the highest ranking due to its exceptional properties such as:
- Incredibly high tensile strength
- Superior environmental stress cracking resistance
- High temperature limits of good thermal tolerance
- Excellent ultraviolet radiation protection
- Creep resistance under constant load for a long time
- No chemical interaction with the surrounding materials
- Extensive flexibility without fracture
The production of the square 4-way extrusion is done through a precise multi-layer technique that ensures:
Exact size retention
- Uniformity of the wall thickness across the entire length
- Completely bonded ducts
- Consistently smooth internal surface
All these factors contribute to the reliable distances for cable blowing, which is very important in the case of fast installations.

Installation Methods (Detailed GCC Guide)
A. Micro-Trenching
- Make a narrow cut trench (60 to 120 mm).
- Put in a square multi-duct.
- Fill with sand and sealing compound.
- Reinstall asphalt.
B. Direct Burial
- Dig the trenches of 60 to 90 cm depth.
- Bed with fine sand.
- Put warning tape.
- Compact properly.
C. Duct-in-Duct (Retrofit)
- Insert a complete 4-way assembly into a larger HDPE pipe.
- This is a perfect way to increase capacity without digging anew.
D. HDD (Horizontal Directional Drilling)
- It can be used for crossing highways.
