Common Types of Optical Fiber
- Single-Mode Fiber: Features a very narrow core that allows only one path for light. It is used for long-distance transmissions (e.g., across cities or oceans) using lasers.
- Multi-Mode Fiber: Has a wider core, allowing multiple paths (modes) for light to travel. It uses LEDs and is typically deployed for shorter distances, such as within a single building or data center.
