Which of the following data communication cable types offers the greatest immunity to electromagnetic "noise"?

Question 1 of 27070

Which of the following data communication cable types offers the greatest immunity to electromagnetic "noise"?

🔍 Key Concepts

• Electromagnetic interference (EMI) and how it affects electrical signals • Physical construction of fiber, twisted pair, and coaxial cables • Which cable types use conductors vs. light to carry information

💭 Think About

• Which of these cable types actually uses metal conductors to carry an electrical signal, and which uses light instead? • How does shielding (or lack of it) affect a cable’s susceptibility to electromagnetic noise? Think about which designs inherently avoid picking up external electrical fields. • Consider which cable type is preferred in environments with very high electrical noise, like near powerful motors or radios.

✅ Before You Answer

• Identify which option does not rely on electrical conduction in copper to transmit data. • Verify which cable design is most commonly used when EMI is a serious problem, such as on ships with lots of high‑power equipment. • Confirm which of the listed cable types is known for very long-distance, high-speed, low-noise communications.
