Flowchart of Optical Cable Duct Laying Process

Fibre interconnection and data room reference Published 03 Dec 2025

Use this reference to prepare product questions for FD SOLUCIONES. Check interfaces, capacity, protection and installation requirements against the current product documentation.

Laying optical cables in ducts involves a structured sequence: planning, duct preparation, cable handling, installation (pulling or blowing), and post-installation checks.

Step-by-

Step Flow1.

Planning and Route Survey

Identify the route and duct network, considering bridges, railways, and road crossings for potential oversizing needs. Determine the number and size of ducts based on current and future network requirements. Obtain necessary permits and approvals from authorities.

2.

Duct Preparation

Clean and inspect ducts and manholes to remove debris. Ensure ducts are properly marked and accessible for cable entry. Apply cable lubricant if required to reduce friction during installation.

3.

Cable Handling

Uncoil cable using a figure-eight method to prevent twisting or kinking. Verify cable specifications: maximum pulling tension, minimum bend radius, and type of cable (uni-tube, multi-tube, armored, or microduct),. Prepare drums and handling equipment, ensuring safety measures and traffic control if working in public areas.

4.

Cable Installation

Pulling Method: Use manual or mechanical pulling devices to draw the cable through the duct, monitoring tension to avoid exceeding the maximum allowed.

Blowing/

Jetting Method: Push the cable a few meters into the duct, then inject compressed air to float the cable along the duct, reducing friction and stress. Choose the method based on duct length, bends, and available machinery; blowing is preferred for long ducts with multiple bends. 5.

Post-

Installation Checks

Ensure cable is not bent below the minimum bend radius and no twisting occurred. Leave cable reserves in figure-eight or circular loops for future maintenance. Inspect splices, connections, and protective elements, ensuring proper installation in distributors or splice boxes.

Document installation details, including cable route, duct numbers, and any deviations from the plan. 6.

Safety and Environmental Measures

Implement traffic control and barricades during installation in public areas. Follow environmental and local regulations for cable handling and duct work. This flow ensures mechanical and optical integrity, minimizes stress on the fiber, and allows for future network expansion.

Proper adherence to tension limits, bend radius, and installation methods is critical to prevent fiber damage and maintain long-term reliability.
