Student       : How can data travel across cities so fast through fiber optic cables? 
 Teacher      : It travels as pulses of light inside a glass or plastic core. 
 Student       : Why doesn't external electrical interference affect the transmission? 
 Teacher       : ..................................

Answer

Because light signals are converted back into electricity before reaching the router.

Answer

However, switches amplify the light by heating up the cable core.

Answer

Consequently, the cable becomes extremely heavy and thick.

Answer

Therefore, the data packet is lost permanently in the dark.

Answer

Because light uses photons rather than electrical electrons, making it completely immune to electromagnetic interference.
