Skills taught in training

By following a D1—D2 Technician training, you will learn to work on fiber optic infrastructures at an early stage: installation, drawing, connection and network control. This is the core of THD deployment.

🚧 Deployment work and infrastructure

• Cable pulling in the air, facade or underground.
• Installation and preparation of boxes, chambers, sleeves and PM/PMZ.
• Installation of garters and optical paths.
• Reading network plans and using GIS/operator tools.

‍

🔧 Optical connection and soldering

• Perform fiber welds (using arc-fusion welder).
• Ensure the organization and cleanliness of optical boxes.
• Perform splices in D1 and D2 according to operator standards.
• Guarantee the conformity of the fibers laid for future D3 operation.

‍

📡 Advanced measurements and quality control

• Use the OTDR to locate faults, cuts, or weakening.
• Analyze reflectometry curves.
• Check the quality of the network before production.
• Write recipe reports and intervention files.

‍

🛠️ Professional situation

• Field interventions in pairs or teams.
• Work in a nacelle, scabbards, telecom chambers.
• Strict compliance with network security rules (FO, electrical, roads).
• Alternating possible to learn directly on site.

Access conditions

• CAP/BEP level accepted in construction, electricity or networks.
• Professional title Fiber Optic Technician highly recommended.
• BS/BE electrical certification useful depending on the construction site.
• La VAE allows you to obtain certification after 1 year of experience.

‍

The steps to integrate a training

• Specialized fiber centers (AFPA, INHNI, GRETA) : direct registrations.
• Short operator training courses : Orange, Axione, SFR under conditions.
• CPF : 100% fundable training courses for adults in retraining.
• Alternation: integration into deployment companies (Circet, SPIE, Constructel...).
