Advantages of fiber optic cable |
Fiber optic cable has following advantages; 1) Higher Bandwidth Fiber optic cable can support and dramatically higher bandwidth and hence data rates than twisted pair and co-axial cable. Currently data rates and bandwidth utilization over fiber optic cable are limited not by the medium but by the signal generation and reception technology used. 2) Less signal attenuation Fiber optic transmission distance is significantly greater than that of other guided media. A signal can run for 50 km without requiring regeneration. we need repeaters at every 5Km for twisted pair and co-axial cable. 3) Immunity to electromagnetic interference (EMI) Electromagnetic interference (EMI) cannot effect fiber optic cable. 4) Resistance to corrosive material Glass is more resistance to corrosive material than copper wire. 5) Light weight Fiber optic cables are much lighter than copper wires. 6) Greater immunity to tapping Fiber optics cables are more immune to tapping than copper cables. Copper cabl ecreates antenna affects that can easily be tapped. |
| >> Disadvantages of fiber optic cable << |
Fiber optic cables too have some disadvantages; 1) Installation and maintenance Since it is new technology, its installation and maintenance requires hight expertize that is not yet available everywhere. It is also dangerous for health of human being. 2) Unidirectional light propagation Propagation of light is unidirectional. If we need bi-directional communication, two fibers are needed. 3) Cost maintenance The cable and the interfaces are relatively more expensive than those of other guided media. |
