Optical Fiber: - Optical fibers are hire thin thread
of glass or plastic, which can serve as a data transmission medium as copper
wire or coaxial cables. The basic difference is that optical fiber transmits
light signals instead of electrical signal. A fiber optic cable consists of
three layers. The inner core is consisting of a cladding around it and outer
protective coating.
Advantages: - The main components of optical fiber of
an optical fiber in data communication system.
- Large band with: - Optical fiber can transmit massive amount of data at very high speed and long distance.
- High Speed: Because of light speed travels faster then electricity, optical fiber can transmit data at much higher speed.
- Low loss: Light signal can travel, at very high with no significant loss over long distance.
- Small size and light weight: Fiber optics is much smaller in size and lightens in weight.
- Security: Optical fiber increase security since it extremely difficult and expensive to top optical signals.
