• A. more than $100GHz$
• B. few$kHz$
• C. less than $1MHz$
• D. less than$1GHz$

Answer 1

The correct option is A more than $100GHz$

Fiber optic cable is composed of microscopic strands of glass. Information in the form of bytes of data can travel through this glass over longer distances and at higher bandwidths, that are data rates, than other types of cable. The order of bandwidth of these cables are as high as $100GHz$ and more.
