- 3. 3 INTRODUCTION Disadvantage of optical fiber over copper wire cable References The advantagesof opticalfiberover wirecable
- 4. 4 INTRODUCTION The light is contained within the glass core and cladding by careful design of their refractive indices. The loss along the fiber is low and the signal is not subject to electromagnetic interference which plagues other methods of signal transmission, such as radio or copper wire links.
- 5. 5 1.During 1930, other ideas were developed with this fiber optic such as transmitting images through a fiber. During the 1960s, Lasers were introduced as efficient light sources In 1970s All glass fibers experienced excessive optical loss, the loss of the light signal as it traveled the fiber limiting transmission distance. 2. This motivated the scientists to develop glass fibers that include a separating glass coating. The innermost region was used to transmit the light, while the glass coating prevented the light from leaking out of the core by reflecting the light within the boundaries of the core. 3. Today, you can find fiber optics used in variety of applications such as medical environment to the broadcasting industry. It is used to transmit voice, television, images and data signals through small flexible threads of glass or plastic.

- 9. Optical hen sending information by an fiber, the information must be encoded or transformed somehow into information that capable of being transmitted through a fiber. The signal needs to be modulated. There are two types of modulation Analog and digital. 9
- 10. 10 Thinner Higher carrying capacity Less signal degradation Light signal Low power Flexible Non-flammable Lightweight The advantages of optical fiber over wire cable
- 11. Disadvantage of optical fiber over copper wire cable 11 Optical fiber is more expensive per meter than copper Optical fiber can not be join together as easily as copper cable. It requires training and expensive splicing and measurement equipment.
