| Fiber Optics Carry More Information |
|
Information is important to every one. We want to communicate with others the fastest, and we want to exchange much information with other people, which result in mass production of information. This demand to nowadays telecommunication systems. As we know light is by now the fastest speed media that we can use, fiber optics use light to transmit the signals, this meet our first requirement, information exchange as fast as possible. As to the second, mass production of information, we need more bandwidth. As we know, bandwidth depends on the frequency of the signal carrier. Light again is the highest frequency carrier among copper, radio, and microwaves. A copper wire can carry signal up to 1MHz over a short distance, radio is 500 to 1000 KHz, microwave is 100GHz, fiber optic is 500 to 1000 The. Here we see the difference and know why fiber optics is the best information carrier. |
