|---|---|---|---|
| Refractive index | 1.46 | 1.5 | 2.5 |
| Attenuation (dB/km) | 0.2 | 0.1 | 1 |
| Bandwidth (MHz/km) | 100,000 | 150,000 | 200,000 |
2. Plastic Fibers
Plastic fibers are an alternative to glass fibers. They are less expensive and more flexible than glass fibers, but they have higher attenuation and lower bandwidth.
Advantages of Plastic Fibers:
- Less expensive
- More flexible
- Easier to install
Disadvantages of Plastic Fibers:
- Higher attenuation
- Lower bandwidth
- Shorter transmission distances
Types of Plastic Fibers:
