Advantages of Optical Fiber
- The optical fibers have greater information carrying capacities than metallic conductors.
- The optical fiber are lighter and smaller.
- The optical fiber cables are cheaper to transport and easier to install than metal cables.
- The optical fibers and fiber cables are very strong and flexible.
- The optical fibers are so slender that they do not break when wrapped around curves of only a few centimeter radius.
- One of the most important advantage of fibers is that they can carry large amount of information in either digital or analog form.
- Optical fiber is well protected from external interference.
- Radar and other signals cannot introduce any interference in the fiber.
- It has greater bandwidth.
- Resistances to high temperature.
Disadvantage of optical fiber
- It is a high investment cost or installation is costly.
- It is need more expansive transmitter and receiver equipments.
- More difficult and expensive to splice then wires.
- It cannot carry electrical power to operate terminal devices.
- At higher optical powers, fiber is more prone to fiber flux, so optical fiber may get damaged.
