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.
