Aerial fiber has a simple job on paper: connect point A to point B. In the field, weight, installation conditions, span requirements and long-term reliability make the equation far more interesting.

Less weight is useful. Engineering what still needs to remain after that weight comes out is where the real work begins. hashtag#IWCS2026 hashtag#FTTx hashtag#AerialFiber hashtag#FiberBroadband hashtag#CableDesign

AI data centres need more connectivity. Their racks and pathways do not get unlimited space. That tension is creating some interesting engineering questions around fiber density, airflow, fire performance and the physical footprint of interconnect cabling.

Today’s AI compute may be replaced in two or three years, while the fibre pathways beneath it may still be in place a decade later. That mismatch changes how AI infrastructure needs to be built. In his latest Forbes Business Council article,

The physical layer has to be designed with enough headroom to keep up. Build for the compute you have today, without having to rebuild for the compute that comes next. Read Ankit Agarwal’s perspective in Forbes Business Council.
