1.光纤电缆:
光纤电缆也称为光纤电缆。它由塑料或玻璃制成。它以光的形式传输信号。光传输系统有3个基本组件,分别是:
- 光源
- 传输介质(光纤)
- 探测器
2.铜线:
铜线用于电气接线。它以电子信号的形式传输数据。它是单根实心导体。
光缆和铜线的区别:
Sr. No. | Basis | Fiber Optic Cable | Copper Wire |
---|---|---|---|
1. | Data Carrier | It carries data in the form of light. | It carries data in the form of electric signals. |
2. | Bandwidth | It offers higher bandwidth. | It offers lower bandwidth. |
3. | Structure | It is thin, lighter in weight and smaller in size. | It is heavier and thicker. |
4. | Environment | It can be laid in different environment because it is more resistant to corrosive materials. | It cannot be laid in different environment because it is more prone to corrosive materials. |
5. | Attenuation | Attenuation is very low. | Attenuation is high. |
6. | Interface | As in this data travel in the form of light, they are not affected by electrical and magnetic interface. | As in this data travel in the form of electric signals, they are affected by electrical and magnetic interface. |
7. | Security | They provide security against the wiretappers, because there is no leakage of light and are difficult to tap. | They does not provide security against the wiretappers, because there is leakage of signals and are easy to tap. |
8. | Cross-talk problem | There is no such kind of any problem. | These are prevalent this problem. |
9. | Effect on charge carriers | In this charge carriers are photons, they do not carry any charge, so they does not get affected. | In this charge carriers are electrons, they carry negative charge, so they get affected when they move in a wire. |
10. | Break-ability | They are easily breakable. | They cannot be easily broken. |
11. | Installation Cost | Installation Cost is high. | Installation Cost is less. |
