The copper vs. fiber debate is reaching a turning point. Fiber leads the way in 2025 and beyond due to lower maintenance costs, scalability, and performance. Studies from Corning and Hexatronic confirm fiber is cheaper to maintain long-term, delivers higher speeds, and eliminates issues like EMI and cable bulk. In high-density data centers, fiber port breakout solutions slash costs by up to 85% compared to copper. Governments worldwide are doubling down on fiber through major infrastructure investments, while the SFP transceiver market itself is on track to more than double by 2033.
