Introduction

Blown Fibre Unit (BFU) Blown Fibre Unit (BFU) Blown Fibre Unit (BFU)

The Blown Fibre Unit (BFU) is a high-performance, pre-connectorised solution purpose-built for fast, efficient last-mile deployment, including FTTH (Fibre to the Home) applications. Designed to accelerate installation and simplify network rollouts, the BFU combines a factory-terminated connector with a blowable ferrule and bare end, ensuring seamless integration into a wide range of customer premises and access network enclosures.

Engineered for flexibility and reliability, the BFU enables rapid fibre deployment with minimal disruption, helping operators reduce installation time while maintaining consistent, high-quality performance.

Available in lengths from 25m to 300m (in 25m increments) and supplied on a compact, ready-to-use spool, the BFU offers a convenient, scalable solution tailored to modern fibre networks.

Features and benefits

  • Pre-connectorised design for faster, simpler installation
  • High-quality LC/APC Grade B connector as standard (alternative options available)
  • Flexible configurations, including single fibre as standard (custom options on request)
  • Wide range of lengths from 25m to 300m to suit varied deployment needs
  • G657.A1 bend-insensitive fibre for improved durability and performance
  • IEC 60794 compliant for assured quality and reliability

HellermannTyton are leaders in product innovation and development when it comes to home connections, fibre to the home and all last mile fibre applications. By incorporating a Blown Fibre Unit (BFU) as the initial fibre feed into the home, we enable a flexible, efficient, and future-ready approach to fibre delivery.

As fibre rollouts accelerate, the increasing volume of telecoms infrastructure can quickly impact streetscapes, leading to congestion, restricted access, and poor curb appeal. An efficient approach is to move key network access points below ground, creating cleaner, more discreet installations without compromising performance.

Our CCPXXL enclosure and TobyBox300 chamber work together to deliver a streamlined, future-ready solution for managing the final connection between network and customer.

Why go underground?

1. Cleaner Installations

Reduces visible hardware on walls and façades and minimises street clutter across dense residential environments.

2. Improved Aesthetics

Creates a more visually appealing finish for end users and is ideal for urban and high-value residential areas.

3. Simplified Network Build

Efficient cable management between external network and internal connection with reduced need for additional wall-mounted equipment.

4. Future-Ready Infrastructure

Supports scalable fibre deployments and is fully compatible with evolving network architectures and technologies in modern network environments.
