STC ODN Project Saudi Arabia: Fiber Network & HDPE Duct Guide
Introduction to the STC ODN Project
Saudi Telecom Company (STC) has been a leader in enabling digital transformation for Saudi Arabia through major investments in fibre optic infrastructure and next-generation (NG) broadband networks. The STC ODN Project is one of the major initiatives that support this transformation; it delivers Optical Distribution Network (ODN) infrastructure across the country through a high-speed FTTx (Fibre to the X) rollout to provide connectivity to cities, industrial areas, smart developments, and Mega projects.
Saudi Arabia is on an accelerated path to achieving its goals within its Saudi Vision 2030, and therefore, reliable digital connectivity has become an important backbone for smart cities, telecommunications networks, government services, and commercial development; through the STC ODN Project, gigabit broadband connectivity will be enabled for homes, businesses, data centres, and areas associated with Emerging Technologies.
The foundation for the advanced fibre network consists of a robust underground infrastructure network of HDPE ducts, PVC conduits, microduct bundles, corrugated ducts, and Telecom provided accessories protecting and organizing the fibre optic cables to keep the telecommunications network durable, scalable and ready for future demands.
To fully understand the Pipe Systems, Technical Standards, Installation Methods, and Supplier Networks associated with the STC ODN Project in Saudi Arabia, it is critical that Contractors, Telecom Engineers, EPC Firms, and Infrastructure Developers become familiar with the above-mentioned components.
Platforms such as “Saudi Ducts” will play a significant role in identifying the component requirements for each stage of the STC ODN Project.
Overview of the STC ODN Project Saudi Arabia
The STC ODN Project in Saudi Arabia is concentrating on constructing the Optical Distribution Network (ODN) which is the physical branch of the telecom network containing fibre optic cables, connecting networks at the backbone to end-users.
Typical components of an ODN include:
– Underground duct networks
– Fibre optic cables
– Distribution cabinets
– Access chambers/manholes
– Fibre termination points
– Splice closures/connection hardware
The primary intent of the network will be to deliver high-capacity broadband services, such as:
– FTTH (Fibre to the Home)
– FTTB (Fibre to the Building)
– FTTC (Fibre to the Cabinet)
– Enterprise fibre connectivity
– Smart city networks
This project will support Saudi Arabia’s increasing demand for:
– 5G Networks
– Cloud infrastructure
– Digital Government Platforms
– Smart Infrastructure
– Industrial Automation
– Data Centres connectivity
Installing the ODN network will require a large-scale underground duct installation project. In this part of the project, HDPE telecom ducts, PVC conduit and the various microduct systems will play a large role.
Companies and EPC Contractors Involved in the STC ODN Project
Large telecom infrastructure deployments like the STC ODN Project Saudi Arabia involve multiple contractors, engineering firms, and construction companies responsible for planning, trenching, duct installation, and fiber deployment.
Some companies commonly involved in telecom infrastructure projects in Saudi Arabia include:
| Company | Role |
|---|---|
| Saudi Telecom Company | Network owner and telecom operator |
| Alcatel‑Lucent Enterprise | Telecom network technology |
| Huawei Technologies | Fiber network equipment |
| Nokia | Broadband and fiber solutions |
| Saudi Binladin Group | Infrastructure construction |
| Al Bawani | Civil works and infrastructure |
| Nesma & Partners | EPC and utility installations |
These companies collaborate to deliver telecom civil works, fiber network deployment, duct bank construction, and smart infrastructure systems required for nationwide broadband connectivity.
Role of Pipes and Duct Systems in the STC ODN Project
The telecom fiber optic lines are highly susceptible to damage from soil weight, moisture, forces and external factors. Therefore, an underground duct system is created to both protect and organize the fiber optics.
For example, in Saudi Arabia’s STC ODN project, the following types of pipelines are used:
– HDPE telecom ducting
– PVC conduit
– Corrugated duct
– Microduct bundles
– Sub-duct system
– Duct spacers and accessories
These types of pipe systems build up an organized and structured underground infrastructure that allows for fast and easy installation, maintenance and upgrading of telecommunications providers’ fiber networks.
HDPE Ducts in STC Fiber Network Infrastructure
The most frequently utilized telecommunications infrastructure pipe system is made of High Density Polyethylene (HDPE) ducting material.
The reason that HDPE is preferred: it has various benefits, including:
- Very flexible
- Corrosion resistant
- Extremely long life (50 years or longer)
- Tough against outside impacts
- Fibers can easily be pulled through smooth inner surface
- UV protection
Typical HDPE Telecom Duct Specifications
| Parameter | Typical Specification |
|---|---|
| Material | PE80 / PE100 |
| Diameter | 40 mm – 200 mm |
| SDR | SDR11 / SDR13.6 / SDR17 |
| Pressure rating | PN10 / PN16 |
| Standard | ISO 4427 |
These ducts are installed underground to create primary telecom pathways for fiber cables.
Microduct Systems for FTTx Networks
Modern fiber optic systems make extensive use of microduct systems.
Microduct bundles comprise many smaller ducts within an outer HDPE pipe. Each duct will carry a sole strand of fiber using air-blown fiber technology.
Some of the advantages of using microducts include:
– Easy to upgrade fibers
– Lower installation costs
– Rapid deployment
– Highly scalable.
The following are typical microduct sizes:
7/5.5 mm
10/8 mm
12/10 mm
16/12 mm
25/20 mm
They are primarily employed in the FTTH framework for residential broadband.
PVC Conduits in Telecom Infrastructure
PVC conduits are commonly used in telecom and electrical installations.
Applications include:
Secondary telecom cable protection
Low voltage electrical conduits
Indoor telecom installations
Utility duct banks
Typical PVC specifications include:
| Parameter | Specification |
|---|---|
| Diameter | 63 mm – 160 mm |
| Standard | IEC 61386 |
| Fire resistance | Flame retardant |
| Installation | Underground or building |
PVC pipes are lightweight and easy to install, making them ideal for secondary telecom networks.
Corrugated HDPE Ducts
Where flexibility + mechanical protection is necessary, it’s common practice to use corrugated ducts.
Typical applications are:
- Road Crossings
- Coastal Infrastructure
- Utility Corridors
- High Load Areas
These products generally feature a double-wall design with a variety of ring stiffness values (e.g., SN4, SN8), which will allow heavy load shortly below surface installations.
Telecom Accessories Used in ODN Projects
Besides pipes, several accessories are required for fiber infrastructure deployment:
Duct spacers
Couplers
End caps
Pulling tapes
Rope systems
Manholes
Fiber splice closures
Joint boxes
These components ensure organized cable routing, maintenance access, and fiber protection.
