Introduction to Fiber Optic Communication Systems
Fiber optic communication systems are the backbone of modern telecommunication networks. They use thin strands of glass or plastic fibers to transmit data in the form of light pulses, enabling high bandwidth and long-distance communication with minimal loss.
Basic Components of Fiber Optic Systems
- Transmitter: Converts electrical signals into optical signals using devices such as laser diodes or light-emitting diodes (LEDs).
- Optical Fiber: The medium through which light signals travel, comprising a core and cladding with different refractive indices.
- Receiver: Converts optical signals back into electrical signals using photodetectors like photodiodes.
