Definition ∞ Fiber optic infrastructure comprises a network of high-speed data transmission lines that use optical fibers to convey information as light pulses. This physical layer technology forms a critical backbone for modern digital communications, offering superior bandwidth and lower latency compared to traditional copper cables. It underpins much of the global internet.
Context ∞ In the realm of decentralized physical networks (DePINs), fiber optic infrastructure is a foundational element for projects aiming to build or decentralize internet services. Leveraging or expanding this infrastructure can lead to more resilient and efficient global data transfer systems. News about DePINs often discusses how they integrate with or enhance existing fiber optic networks.
