The process of air blowing fiber optic cable typically involves the following steps:
Preparing the conduit: The conduit or duct where the fiber optic cable will be installed needs to be inspected and prepared. Any obstructions, debris, or blockages should be removed to ensure a clear pathway for the microduct and fiber optic cable.
Installing the microduct: A lightweight and flexible microduct is inserted into the conduit. The microduct is typically larger in diameter than the fiber optic cable to allow for easy installation and future upgrades. The microduct is pushed or propelled through the conduit using compressed air or gas. Specialized equipment, such as a blowing machine, is used to create the necessary airflow.
Securing the microduct: Once the microduct is in place, it is secured at regular intervals along the conduit using brackets or other appropriate fastening mechanisms. This helps prevent movement or dislodging of the microduct during the subsequent fiber optic cable installation.
Preparing the fiber optic cable: The fiber optic cable is prepared for installation. This includes removing any outer sheathing, organizing the fibers if necessary, and attaching a pulling or blowing apparatus to the cable end.
Connecting the cable to the microduct: The prepared end of the fiber optic cable is connected to the blowing apparatus, which is then attached to the microduct. The connection should be secure to ensure proper fiber optic cable deployment.
Blowing the fiber optic cable: Compressed air or gas is used to blow or push the fiber optic cable through the microduct. The blowing machine or equipment controls the airflow and monitors the cable's speed and tension during the installation process. The blowing continues until the entire length of the fiber optic cable is deployed and reaches the desired endpoint.
Testing and verification: Once the fiber optic cable is installed, it is important to test and verify its integrity and performance. Specialized testing equipment is used to check for any signal loss, attenuation, or other issues. The cable connections and splices are also inspected to ensure proper functionality.
It's important to note that the specific process may vary depending on the equipment and techniques used by different manufacturers or installers. Certified technicians or professionals with experience in air blowing fiber optic cable installations should be involved to ensure a successful and reliable installation.
