In a recent presentation at the Energizing Innovations Webinar on January 18, 2024, Noah Taylor of AFL, a leading provider of solutions for the energy industry, shed light on the revolutionary ADSS (All-Dielectric Self-Supporting) fiber optic cables. AFL, founded in 1984, has positioned itself as an industry leader, and Taylor’s presentation explained the potential and advantages of ADSS technology in both distribution and transmission settings. 

What Is AFL-ADSS®? 

The AFL-ADSS® cable stands out for its unique features, making it an ideal choice for live-line installations. The ADSS cable requires no additional support or messenger wires during installation, offering a seamless and cost-effective solution for establishing fiber optic networks.  

One of the main aspects of ADSS is its dielectric nature, meaning no conductive or metallic elements. Because of this, NESC section 235 states that no clearance is required between conductors and ADSS cables. 

The self-supporting design spans aerially from pole to pole, supported only by pole attachment hardware, reducing installation time and cost while enhancing design life and reliability. With pole placement flexibility and limited maintenance requirements, ADSS is a versatile choice for optimizing right-of-way usage. AFL provides two types of ADSS cables: gel-filled or gel-free, catering to different project requirements.

Advantages of ADSS 

Taylor explained in his presentation that clearance concerns are effectively addressed as ADSS can be placed in the communications or supply space of a distribution pole, allowing utilities to maximize right-of-way potential without compromising safety. 

Hardware solutions offered by AFL to complement ADSS cables include dead-ends, trunnions, vibration dampers, and downleads. These components enhance installation security, reduce Make Ready efforts, and ensure scalability. 

To address power supply zone certification concerns, AFL strategically places cable storage, sealed closures, and hardened connector ports in the Comms Space, providing flexibility without compromising accessibility. This approach drives down installation and facilitates ease of access for contractors with basic equipment. 

Taylor concluded the presentation by going over AFL’s Plug and Play Connectivity option, which are cost-effective and allow for scalability.
