ADVANTAGES AND DISADVANTAGES; COAXIAL CABLE, FIBER OPTIC CABLE & TWISTED PAIR

COAXIAL CABLE
- advantages
  • sufficient frequency range to support multiple channel, which allows for much greater throughput.
  • lower error rates. because the inner conductor is in a Faraday shield, noise immunity is improved, and coax has a lower error rates and therefore slightly better performance than twisted pair.
  • greater spacing between amplifiers coax's cable shielding reduces noise and crosstalk, which means amplifiers can be spaced farther apart than with twisted pair.
- disadvantages
  • more expensive to install compare to twisted pair cable.
  • the thicker the cable, the more difficult to work with.
FIBER OPTIC CABLE
- advantages
  • system performance
  • greatly increased bandwidth and capacity
  • lower signal attenuation (loss)
  • immunity to electrical noise
  • immune to noise (electromagnetic interference and radio frequency interference)
  • less restrictive in harsh environments
  • overall system economy
- disadvantages
  • fiber optic component are expensive
  • fiber optic transmitters and receivers are still relatively expensive compared to electrical interfaces
  • the lack of standardization in the industry has also limited the acceptance of fiber optics.
TWISTED PAIR CABLE
- advantages
  • using telephone wires are their relative low cost and their availability
  • handled a data flow of up to approximately one megabit per second (Mbps) over several hundred feet
  • small local area network with a limited number of users, twisted pair is an ideal choice because it is both inexpensive and easy to install.
- disadvantages
  • susceptibility to signal distortion errors and the relatively low transmission rates they provide over long distances.

  6. Optic fibers are used to connect servers and users in a variety of network settings and also help in increasing the accuracy and speed of data transmission.

  9. A fiber-optic system is similar to the copper wire system that fiber-optics is replacing. The difference is that fiber-optics use light pulses to transmit information down fiber lines instead of using electronic pulses to transmit information down copper lines. Looking at the components in a fiber-optic chain will give a better understanding of how the system works in conjunction with wire based systems.At one end of the system is a transmitter. This is the place of origin for information coming on to fiber-optic lines. The transmitter accepts coded electronic pulse information coming from copper wire. It then processes and translates that information into equivalently coded light pulses.Think of a Fiber Cable in terms of very long cardboard roll (from the inside roll of paper towel) that is coated with a mirror on the inside.If you shine a flashlight in one end you can see light come out at the far end - even if it's been bent around a corner.
