She gathered the following information from an internet site. Copper cable The electrical transmission through a copper cable has a bandwidth of approximately 108 Hz and the transition time for each pulse is 10 8 second. Due to electromagnetic interference (EMI) and energy loss, the signal loss is greater than 20 dB/km. The cable is large, heavy and expensive, and the signal remains electrical. Fibre optics The transmission of a signal through an optic fibre has a bandwidth of 1014 Hz and transition time for each pulse is 10 11 second. The glass used to make the optical fibre is cheaper, smaller, lighter and more fragile than copper cable. There is no EMI and little energy loss. The signal loss is approximately 0.2 dB/km, but the signal must be converted from electrical to optical and then back to electrical. (a) Use the information gathered by Lee to complete the table comparing copper cables with fibre optics in relation to their band width, signal loss and transition time for pulses. Cable Band width Signal loss 2 Transition time per pulse Copper cable Fibre optic cable (b) Using Lee s gathered data, explain why the fibre optic cable has a faster rate of information transfer than the copper cable. ............................................................................................................................... ............................................................................................................................... ............................................................................................................................... ............................................................................................................................... 18 2 Marks Question 26 (4 marks) Explain ONE advantage and ONE disadvantage of using radio waves in communication. 4 ......................................................................................................................................... ......................................................................................................................................... ......................................................................................................................................... ......................................................................................................................................... ......................................................................................................................................... ......................................................................................................................................... ......................................................................................................................................... .........................................................................................................................................
