Single-Mode Fiber
Fiber optic cables form the foundation of modern high-speed communication networks, enabling long-distance data transmission with minimal loss and strong immunity to electromagnetic interference. Below is a structured overview of the main cable types, their technical details, applicable standards, and real-world use cases—all aligned with current industry practices. Single-Mode Fiber (SMF) SMF is designed for long-distance, high-bandwidth communication, allowing only one mode of light to travel through a narrow core.
