Study Notes
Fiber Optic Communication
- Ethernet standards support transmission via light signals through optical fiber, enabling long-distance communication without copper cabling.
- Fiber optics offer enhanced security due to the absence of radio frequencies that could be intercepted.
- Light signals travel much farther over fiber optic cable than over copper. Radio frequencies have shorter transmission ranges.
- Fiber optic signals are unaffected by radio frequencies in the environment, making them suitable for environments with high RF activity like manufacturing settings.
Fiber Optic Cable Structure
- Fiber optic cable is significantly smaller than copper cable.
- The fiber core is very small, protected by cladding (low reflective index, absorbs light), and a buffer coating(protection).
- A ferrule is a ceramic protector surrounding the fiber core within the connector.
- The fiber core itself transmits light signals from a light source (LED or laser) to the receiving equipment. The light bounces through the core.
Fiber Optic Types
- Multi-mode Fiber: Used for short-range communication (up to 2 km). Uses LEDs as light sources. Multiple reflections (modes) occur inside the wider core.
- Single-mode Fiber: Used for long-range communication (up to 100 km). Uses lasers as light sources. Narrow core allows for single path of light signals.
