Advantage of optical fibre

Options

A. High bandwidth and EM interference
B. Low bandwidth and EM interference
C. High band width, low transmission capacity and no EM interference
D. High bandwidth, high data transmission capacity and no EM interference.

Answer

### Step-by-Step Solution:

1. **Understanding Optical Fiber Communication**:
- Optical fiber communication uses light to transmit data, as opposed to electrical signals used in traditional cables. This fundamental difference allows for various advantages.

2. **High Bandwidth Capacity**:
- One of the primary advantages of optical fiber is its high bandwidth capacity. This means that it can carry a large amount of data simultaneously compared to electrical cables.

3. **Low Signal Loss**:
- Optical fibers experience extremely low signal loss over long distances. This is crucial for maintaining the integrity of the data being transmitted, especially over long distances.

4. **No Electromagnetic Interference (EMI)**:
- Unlike electrical cables, optical fibers are immune to electromagnetic interference. This means that external electrical noise does not affect the signal being transmitted, leading to clearer and more reliable communication.

5. **Conclusion**:
- Therefore, the main advantages of using optical fiber communication over electrical cable transmission are its high bandwidth capacity, high data transmission capacity, and immunity to electromagnetic interference.

### Final Answer:
The advantages of optical fiber communication include:
- High bandwidth capacity
- High data transmission capacity
- No electromagnetic interference (EMI)
