光纤电缆和同轴电缆都是引导介质的类型。
光缆：
光纤是一种引导介质，由塑料和玻璃制成，用于以光形式或光学形式传输信号。它提供高带宽 (B)。它的安装和实施不像同轴电缆那么容易。
同轴电缆：
同轴电缆是一种由塑料制成的引导介质，用于传输信号的铜线是电形式而不是光形式。它的安装和实施很容易，但效率不如光纤，而且与光纤相比，它提供了中等的高带宽 (B)。
| S.NO | Optical Fiber | Coaxial Cable |
|---|---|---|
| 1. | Optical Fiber is used to transmit the signal is in light form. | Coaxial Cable is used to transmit the signal is in electrical form. |
| 2. | Optical Fiber is made of plastics and glasses. | Coaxial Cable is made of Plastics, copper wires etc. |
| 3. | Optical Fiber is high efficient. | While Coaxial Cable is low efficient. |
| 4. | The cost of optical fiber is high. | The cost of coaxial cable is less. |
| 5. | Optical cable is lighter in weights. | Coaxial cable is heavier than optical fiber in weight. |
| 6. | Optical fiber’s diameter is small. | Coaxial cable’s diameter is larger than optical fiber. |
| 7. | Installation and implementation of optical fiber is difficult. | Installation and implementation of coaxial cable is easy. |
| 8. | In the optical fiber, there is highest noise immunity as they are unaffected by the electrical noise. | Coaxial cable has finest noise immunity due to the shield provided. |
| 9. | These cables are not affected due to external magnetic field. | Coaxial cables are less affected by the external magnetic field. |
| 10. | Power loss happens in optical fiber is caused by the absorption, scattering, dispersion and bending. | Loss of power in coaxial cables is due to conduction only. |
