As Europe accelerates its digital transformation, France has emerged as a pioneer in fiber optic infrastructure, with ambitious goals to deploy high-speed connectivity nationwide. In 2023, our company partnered with Orange France, one of the country’s leading telecom operators, to execute a comprehensive FTTH (Fiber-to-the-Home) upgrade project using our cutting-edge 1fo Round Fiber Drop Cable. This case study delves into how our non-metallic, bend-insensitive drop cable addressed Orange’s unique challenges in urban and suburban environments, optimizing network performance while reducing deployment costs.

Project Overview

Client: Orange France
Project Name: FTTH Round Fiber Drop Cable Deployment
Location: Major cities and suburban areas across France (Paris, Lyon, Marseille, Toulouse, etc.)
Objective: Upgrade last-mile connectivity for 2 million households with high-speed fiber, leveraging bend-insensitive drop cables for efficient installation in tight spaces.
Solution: Deploy 1fo Round Fiber Drop Cable with G657A2 fiber, designed for low attenuation, superior bend performance, and safe co-installation with electrical infrastructure.

The French Telecom Landscape: Challenges and Demands

France’s telecom sector is driven by the government’s France 2030 plan, aiming to provide 100% fiber coverage to all households by 2030 . As of 2024, FTTH penetration stood at 68%, with Orange leading the market with 35% share in fiber subscriptions . However, deploying fiber in densely populated urban areas (e.g., Paris’ historic districts) and complex suburban networks posed critical challenges:

Limited Installation Space: Tight ducts, narrow walls, and congested utility pathways in older buildings.

Electrical Safety Regulations: Strict norms for separating fiber cables from high-voltage electrical systems.

Cost Efficiency: Need to minimize labor and material costs for mass deployment.

Performance Consistency: Ensuring low latency and high bandwidth over short to medium distances.

Orange required a drop cable that could navigate these hurdles while supporting its vision for 10G PON-ready infrastructure and 5G backhaul compatibility.

Introducing 1fo Round Fiber Drop Cable: The Last-Mile Solution

Our 1fo Round Fiber Drop Cable (1-core) is engineered to redefine last-mile fiber deployment. Here’s how it addressed Orange’s needs:

1. Superior Bend Performance with G657A2 Fiber

Bend-Insensitive Design: Featuring ITU-T G657A2 fiber, the cable maintains low attenuation (≤0.1dB) even at bending radii as small as 7.5mm (15x cable diameter), compared to traditional G652D fiber’s 30mm minimum . This allows installation in tight corners, conduits, and wall cavities without signal loss—critical for Paris’ historic buildings with confined spaces.

Dynamic Flexibility: The cable withstands repeated bending during installation, reducing the risk of microbending-induced failures. Field tests showed 99.98% signal stability after 100+ bending cycles .

2. Non-Metallic Construction for Safety and Compliance

Fully Insulated Design: The cable’s aramid yarn strength members and PE sheath eliminate metallic components, making it safe for parallel installation with electrical wiring. This complied with France’s NFC 32-070 safety standards, reducing installation risks and avoiding costly insulation upgrades .

Electromagnetic Interference (EMI) Immunity: Non-metallic materials ensure zero interference from power lines, ideal for mixed utility conduits common in French urban areas.

3. Low Attenuation for Consistent Performance

Ultra-Low Loss: The G657A2 fiber delivers attenuation of ≤0.35dB/km at 1310nm and ≤0.22dB/km at 1550nm, enabling reliable high-speed transmissions (up to 10Gbps) over distances of 2+ km—suitable for both urban hubs and suburban extensions .

Temperature Stability: Maintains performance across -40°C to +70°C, adapting to France’s varied climatic zones from the Alps to the Mediterranean coast.

4. Round Design for Installation Efficiency

Aerodynamic Profile: The circular cross-section (6mm diameter) glides smoothly through existing ducts, reducing pulling force by 40% compared to flat drop cables. This minimized installation time and labor costs, especially in Paris where duct congestion is severe .

Easy Handling: The cable’s flexible jacket (LSZH or PE options) resists abrasion and allows simple routing through walls, ceilings, and conduits. Orange’s technicians reported 30% faster installation versus traditional cables .

Modular Splicing: Compatible with field-installable connectors (e.g., SC/APC), enabling on-site termination without specialized equipment—critical for scaling the project across 20+ cities.

Complementary Accessories for Seamless Deployment

To optimize the 1fo Round Fiber Drop Cable’s performance, we provided Orange with a suite of specialized accessories:

1. Pre-Connected Fiber Optic Termination Boxes

IP65-rated enclosures with integrated splice trays, designed for outdoor and indoor use. Their compact size (150x100x50mm) fit into tight wall spaces, supporting up to 12 fibers per box.

2. Bend-Protection Clips

Flexible clips that secure the cable at bends, maintaining the minimum bending radius and preventing signal degradation. These were essential for installations in Lyon’s narrow alleyways.

3. Duct Blowing Accessories

Low-friction adapters and lubricants to facilitate cable blowing through microducts, reducing deployment time in Marseille’s suburban networks.

Deployment Strategy and Execution

1. Pilot Project in Paris’ 5th Arrondissement

We initiated a pilot in Paris’ historic district, where tight quarters and listed buildings posed extreme installation challenges. The 1fo cable’s bend performance allowed routing through 75mm-diameter conduits (half the standard size), reaching 10,000 households in 3 months—2x faster than Orange’s previous deployments.

2. Nationwide Rollout Plan

Building on the pilot’s success, we scaled the project to:

Urban Centers: Deployed in Lyon, Toulouse, and Bordeaux, prioritizing high-density areas with complex duct systems.

Suburban Regions: Targeted commuter towns near Paris, where the cable’s long-distance performance enabled cost-effective coverage.

Rural Outliers: Limited deployments in remote villages, leveraging the cable’s durability for outdoor 架空 installations.

3. Training and Local Collaboration

Our team conducted workshops for 500+ Orange technicians, focusing on:

Safe handling of non-metallic cables

Field termination techniques for G657A2 fiber

Duct blowing best practices
This led to a 95% first-time installation success rate, minimizing rework costs.

Results and Impact
