  • Cable blowing during optical cable construction in communication pipelines

    Cable blowing during optical cable construction in communication pipelines

    Cable blowing is the process of installation of optical fiber cable into a pre-installed duct. In this article, we'll guide you through the entire fiber optic cable blowing procedure, highlighting the essential tools, the advantages over traditional methods, and the common challenges. Cable installation by using high speed air flow combined with additional mechanical pushing force is called as “blowing or jetting”. This method is particularly common in the deployment of Fiber-to-the-Home (FTTH) networks and last-mile access. Cable pay off the top of reel: This helps installer to have control and manage the pay-off, do not pay cable from the bottom of the reel which can cause loosening of the windings and loss of control.
