Which of the following communication system has maximum band width ?

Options

A. Optical fibre communication
B. Skywave communication
C. Line communication
D. Statellite communication

Answer

To determine which communication system has the maximum bandwidth among the given options, we can analyze each option based on their characteristics.

### Step 1: Understanding the Options
The options provided are:
1. Optical Fiber Communication
2. Sky Wave Communication
3. Line Communication
4. Satellite Communication

### Step 2: Analyzing Each Communication System
- **Optical Fiber Communication**: This system uses light to transmit data through fiber optic cables. It is known for its high bandwidth capabilities, often exceeding 100 GHz. The data can travel long distances without significant loss, making it very efficient for high-speed communication.

- **Sky Wave Communication**: This method utilizes radio waves that are reflected off the ionosphere. While it can cover long distances, its bandwidth is limited compared to fiber optics. The frequency range typically used is lower than that of optical fibers.

- **Line Communication**: This refers to communication systems that use physical wires (like copper cables) to transmit signals. The bandwidth is generally lower than that of optical fibers, often limited to a few MHz.

- **Satellite Communication**: This system uses satellites to relay signals. While it can cover vast distances and has a reasonable bandwidth, it is still not as high as that of optical fiber communication.

### Step 3: Comparing Bandwidths
Based on the analysis:
- Optical Fiber Communication: More than 100 GHz
- Sky Wave Communication: Limited bandwidth (typically in MHz)
- Line Communication: Limited bandwidth (typically in MHz)
- Satellite Communication: Moderate bandwidth (lower than optical fiber)

### Step 4: Conclusion
From the comparison, it is clear that **Optical Fiber Communication** has the maximum bandwidth among the given options.

### Final Answer
The communication system with the maximum bandwidth is **Optical Fiber Communication**.
