ICT Module 4 Revision

ICT Attenuation and cable type What is attenuation What cable should be used between buildings and why?

ICT Attenuation What are common causes for attenuation in copper cables? How can you limit attenuation on a cable run?

ICT Cross Talk What can cause cross talk in copper cables? What should be done to ensure cross talk does not occur?

ICT Waves What is meant by “the frequency” of a wave? What is meant by “the amplitude” of a wave? What is meant by the period of a wave?

ICT Fibre optic signalling How is data represented when it is sent down a fibre optic cable (two possible answers)?

ICT Wire map test What problems can be detected when using a wire map test on a copper cable?

ICT Noise and cross talk What are the causes of noise and cross talk?
