Comparison should include
- type of signal (voltage, modulated radio frequency, digital modulation, light pulses)
- signal propagation distance limitations
- signal attenuation
- crosstalk
- structured cable certification test
- certification standards.
Process/Skill Questions:
- What are the factors that determine length limits for cables?
- What is the cause of signal attenuation on cables?
- What is the purpose of each of the tests performed in the cable certification process?
