This article discusses optical fiber trends in 2024-2025. Single-mode fibers (OS1/OS2) excel in long-distance FTTH and CATV (1550 nm for video). Multimode fibers (OM1-OM5) suit shorter distances, with OM3 popular for cost-effective FTTH and enterprise networks, supporting 10 Gbps up to 300m. OS2 is ideal for long-term, high-performance use, while OM3 fits budget-sensitive projects.
