Which type of cable will not pick up electric noise or generate electromagnetic radiation that may interfere with other signals?

• A. Copper
• B. Fiber optic
• C. Coaxial
• D. Twisted pair

Answer: (B)

Fiber optic cables are the correct choice because they use light to transmit data instead of electrical signals. This technology inherently prevents the cables from picking up electromagnetic interference (EMI) or generating electromagnetic radiation that could disrupt other signals. The absence of electrical currents in fiber optic cables eliminates susceptibility to electric noise, making them ideal for environments where interference is a concern. Copper cables, coaxial cables, and twisted pair cables, on the other hand, rely on electrical signals for data transmission. These types of cables can easily pick up electromagnetic interference from external sources, making them less effective in scenarios where maintaining signal integrity is crucial. Fiber optics provide a distinct advantage in terms of data integrity and noise resistance in any communication network.
