Saudi Telecom Company (STC) – Approved HDPE Plain Ducts, Mini/Micro Ducts & HDPE Corrugated Ducts (HDPE-CD)

Complete Solutions for STC FTTX, OSP, Backbone & Access Networks

Saudi Telecom Company (STC) operates one of the most advanced fibre-optic networks in the Middle East. To meet its aggressive expansion of FTTH, 5G backbone, OSP telecom routes, metro networks, long-distance routes and smart-city infrastructure, STC enforces two key specifications:

  • STC VD-101: Plain HDPE Ducts (Main, Mini, Micro) & Accessories

  • STC VD-102: HDPE Corrugated Ducts (HDPE-CD) & Accessories

At Saudi Ducts, we supply the complete STC-approved product range covering both VD-101 & VD-102 — including plain ducts, mini/micro ducts, corrugated ducts, sub-duct bundles, couplers, caps, connectors, and all accessories.

STC’s Network Build Strategy — Standards, Scale & Modularity

STC designs its nationwide telecom rollout around modular, repeatable building blocks: plain HDPE main/mini/micro ducts and corrugated HDPE-CD systems that can be deployed for long-distance backbone, urban distribution and FTTH access. The emphasis is on standardization (VD-101 / VD-102) — fixed OD/ID sizes, SDR/PN ratings, color coding and MIC numbering — so every contractor and supplier follows the same rules for manufacture, testing and installation. This standard approach enables fast approvals, consistent quality across regions and easier asset management over a 50-year lifecycle.

Key elements STC enforces: PE100 virgin material, PN16 pressure capability for sub-ducts used in air-blown fibre, meter markings and QR/MIC tagging for traceability. These standards reduce rework and speed up handovers to operations teams.

How STC Deploys Ducting — Practical Methods & Best Practices

STC uses several installation approaches depending on the environment:

• Direct Bury Methods

Used for intercity and long-haul backbone routes, typically using 110 mm and 77 mm HDPE Corrugated Ducts (HDPE-CD) or large plain HDPE ducts for maximum protection.

• Micro-Trenching & Multi-Duct Bundles

For dense urban and FTTH zones, STC deploys 2-way, 4-way and 7-way bundles of mini/micro ducts to reduce civil works and minimize traffic disruption.

• HDD (Horizontal Directional Drilling)

For road crossings, highways, and critical zones, STC mandates HDD with corrugated ducts due to their high crush resistance and flexibility.

• Air-Blown Fibre Installations

STC relies heavily on low-friction micro-ducts and PN16-rated sub-ducts to support high-speed cable blowing over long distances with minimal friction and low pulling tension.

Best practices include:

  • Factory pre-bundling of ducts

  • Meter marking on every duct

  • Transparent windows on outer sheaths when required

  • Steel-drum delivery for safe handling

  • Pre-tested couplers and seals

  • Pre-configured color-coded sub-duct sequences

These practices significantly reduce installation time and increase long-term reliability.

Key Challenges in Building Saudi Telecom Infrastructure

STC faces a unique set of engineering and environmental challenges across Saudi Arabia:

• Extreme Climate Conditions

High UV, intense heat, and thermal expansion stresses ducting materials.
Solution: UV-stabilized, thermally tested PE100 materials and strict thermal property requirements.

• Diverse Terrain Types

Urban congestion, rocky regions, deserts, and coastal environments demand different ducting approaches.
Solution: Corrugated HDPE-CD ducts for variable soils & heavy loads; micro-duct bundles for tight urban corridors.

• Limited Trench Space in Urban Zones

Older cities and high-density metro areas leave little space for civil work.
Solution: Micro-trenching and compact duct bundles.

• Quality Control & Traceability Requirements

Large-scale projects require strict inspection and documentation.
Solution: MIC numbers, QR coding, meter marking, full test reports, and standard accessory kits.

• High Volume Logistics & Site Management

Projects span thousands of kilometers.
Solution: Steel reel packaging, regional stock availability, and ready-site accessory kits.

How STC Overcomes These Challenges — Engineering & Operational Solutions

• Material Engineering

STC requires virgin PE100 with strict carbon black, UV stabilizer, and thermal requirements to withstand Saudi’s environment.
PN16-rated sub-ducts ensure blowing pressure resistance and long-term duct stability.

• Smarter Installation Methods

  • Pre-bundled ducts reduce twisting and field assembly problems

  • HDD and corrugated ducts eliminate the need for concrete encasement

  • Micro-trenching accelerates FTTH deployment in congested areas

• High Traceability & Zero-Error QC

STC mandates:

  • QR codes

  • MIC numbering

  • Meter marking

  • Batch test certificates

  • Routine and type testing

This ensures issues are caught early and inspections pass on the first attempt.

• Logistics Optimization

  • Steel reels protect ducting during transport

  • Pre-cut drum lengths speed up deployment

  • Ready accessory kits eliminate on-site material shortages

These combined measures reduce downtime and improve network readiness.

Future-Proofing — How STC Builds a Network Ready for the Next 30 Years

STC follows a future-ready infrastructure approach to support nationwide 5G, IoT, data centers, smart grids, and municipal smart-city projects.

Key strategies:

• Modular Micro-Duct Systems

Allow new fibre cables to be installed without digging — perfect for future bandwidth upgrades.

• Unified Color Codes & MIC Identification

Helps field teams instantly identify duct capacity, spare ducts, and service routes.

• Standardization Across All Regions

VD-101 and VD-102 define consistent conduit dimensions, colors, connectors, and accessories — enabling predictable supply, installation, and maintenance.

• Scalability for Mega Projects

STC’s duct systems support large-scale projects like NEOM, The Line, Red Sea Project, Qiddiya, and future data transmission corridors.
