Answer :

Final answer:

Fiber optic cables are made of ultra-high purity glass for efficient data transmission over long distances, offering advantages like low loss and high bandwidth.


Explanation:

Fiber Optic Cables: Fiber optic cables are made of special ultra-high purity glass, primarily silica, with impurity levels reduced to parts per billion for optimal performance in data transmission.

Example: Optical fibers are long solid glass wires that trap lightwaves inside, allowing data transmission over long distances with minimal loss.

Advantages of Fiber Optic Cables: Fiber optic cables offer advantages such as low loss, high bandwidth, and reduced crosstalk compared to electrical-based systems, making them ideal for long-distance communications.
