5 Steps to Effectively Install Blown Fiber

1. Site Survey & Planning

The first crucial step in a blown fiber installation is conducting a thorough site survey. It involves assessing the route where the fiber will be installed, identifying potential obstacles, and planning the layout of micro ducts.

During this phase, the team determines the most efficient path for the ductwork, considering factors like minimum bending radius and avoiding areas of high friction that could impede the installation process.

2. Installing the Micro Ducts

Once the planning is complete, the installation of micro ducts begins. These are small, flexible conduits that house the fiber cables. Technicians must ensure these ducts are properly secured and protected within walls or underground channels.

Special attention is given to maintaining airtight connections, as the efficiency of the blowing process heavily relies on the integrity of the air pressure within these ducts. Lubricants can also be crucial to reduce friction and facilitate a smoother installation of the fiber when it is blown through later.

3. Blowing the Fibers

The third step is blowing the fibers into the installed micro ducts. It is done using machines that apply compressed air to gently push the fiber cables through the conduit.

The process is carefully monitored to ensure consistent air pressure and the fibers are not damaged. This method allows for fibers to be blown over considerable distances, expanding the network’s reach where needed and minimizing the physical strain on the cables.

4. Splicing & Termination

After the fibers are in place, each end must be spliced and terminated to establish a functional network. Splicing involves joining two fiber ends mechanically or using fusion to ensure no signal loss.

Termination then involves connecting these fibers to the necessary equipment or patch panels. This step is critical to integrating the new fibers into the existing network infrastructure, and precise workmanship is required to maintain the integrity and performance of the network.

5. Testing & Commissioning

The final step involves testing and commissioning the newly installed fiber network. Technicians will perform various tests to confirm that all components are properly connected and functioning as expected.

Tests include measuring light loss through the fiber to ensure there are no breaks or imperfections affecting performance. Once all parameters are verified and the system meets all specified requirements, the installation is considered complete and ready for active service.

Fiber Optic Cables

The core component of any blown fiber installation, these cables are designed to be lightweight and durable enough to withstand the stresses of being blown through micro ducts.

There are different fiber optic cables types that can be installed with this method have a protective coating that reduces friction and protects the delicate glass fibers inside from damage during installation.

Micro Ducts

Micro ducts are small, flexible conduits that provide the pathway for fiber optic cables within a building’s walls or under its infrastructure. These ducts are crucial because they facilitate future network expansion; additional fibers can be blown into spare ducts without disturbing the existing setup.

Blowing Equipment

Blowing equipment includes machines and tools that use compressed air to propel fiber optic cables through the micro ducts.

The equipment must be precisely calibrated to manage the air pressure and volume, ensuring that the cables are installed quickly and without damage, expanding the network’s capabilities without the need for extensive physical labor.

Connectors & Closures

Connectors and closures join and protect the ends of the fiber optic cables where contact is made with other network components or where cables end. These are essential for safeguarding the integrity of the fiber connection points from environmental factors and ensuring the network operates efficiently.

Common Applications

Blown fiber technology is predominantly utilized where high-speed internet is crucial and future scalability is a priority. Common applications include large office buildings, hospitals, universities, and data centers.

Blown fiber is a flexible technology that allows easy upgrades as the demand for higher bandwidth increases, making it an ideal choice for growing businesses and institutions.

Challenges in Blown Fiber Installation

One of the main challenges in blown fiber installation is ensuring that the micro ducts are clear of any obstructions before the fiber is blown. It requires meticulous planning and inspection of the conduits.

Additionally, managing the airflow correctly to avoid damaging the fiber during installation is critical, necessitating skilled technicians who can adjust to the unique conditions of each site.


Do I need professional help for blown fiber installation?

Yes, professional installation is recommended for blown fiber due to the complexity of the process and the specialized equipment required. Proper handling ensures the integrity and performance of the installed fibers.

What are the benefits of blown fiber?

Blown fiber offers remarkable flexibility for future expansions without significant disruptions. It also minimizes the need for multiple conduits since additional fibers can be added easily, and it provides a scalable solution to meet increasing data demands.

How does blown fiber work?

Blown fiber involves inserting fiber optic cables into pre-installed micro ducts using compressed air. This method is highly efficient for covering long distances within buildings or across campuses, ensuring that fibers are laid with minimal physical strain and risk of breakage.

Key Takeaways

Blown fiber installation offers a robust solution for modern data needs, combining efficiency with the capacity for future expansion.
