What is an advantage of optical fiber communication?

Signals degrade rapidly
Transmission is immune to radio interference
Less bandwidth compared to copper
Lower cost than twisted pair cables

The correct answer is: Transmission is immune to radio interference

Optical fiber communication offers significant advantages, one of which is its immunity to radio interference. This is primarily due to the nature of light transmission in fiber optics. Unlike electrical signals used in copper cables, which can be disrupted by electromagnetic interference (EMI) from various sources such as nearby electrical equipment or radio waves, optical fibers use light to transmit data. This makes them highly resistant to such interference, allowing for clearer and more reliable communication. The benefits of this immunity are particularly notable in environments with high levels of electronic noise, such as industrial settings or areas with a lot of wireless communication. Fiber optic systems can maintain signal integrity over longer distances and at higher speeds compared to their copper counterparts. This reliability and performance are fundamental reasons why optical fiber is favored in modern telecommunications and networking infrastructures.
