How do fiber optic cables transmit data? 
Fiber optic cables transmit data using light signals. These cables contain thin strands of glass or plastic that guide light through total internal reflection. Light pulses, generated by lasers or LEDs, travel along the fibers, encoding data as variations in light intensity. This method allows for high-speed, long-distance transmission with minimal signal loss and electromagnetic interference.
Optical Fibers

Fiber cables consist of many small optical fibers. These fibers are very thin, to be specific, they are thick with less than one-tenth of the hair. Although they are thin, they have a lot going on. Each optical fiber has two parts.
1. The core is an optical fiber where light travels. The cover is made of glass with a very low disturbance index, which gives rise to a total internal reaction. 
2.    The Cladding is the second layer of optical fiber that wraps around the core. It is usually made of a deep layer of plastic or glass to create a total internal bend.
These two parts work jointly to generate a fact called total internal reflection. The total internal reflection is how the light escapes, without the fibers being able to move down. This is when light hits the mirror at a very low angle, which is less than 42 degrees, and reflects it again as if it were reflecting against a mirror. Cladding keeps light in the core because the glass it is made of has a different optical density or a lower refractive index. Both of these conditions indicate how the glass bends and therefore slows down the light.
How fast can fiber optics transmit data?
Light is transmitted under fiber in LED or laser pulses that travel extremely fast. These pulses contain binary data, a coding system that creates everything we see on the Internet. The binary code is made up of bits, which are just another zero. These bits drive mail in organized eight-part patterns that are known as bytes. Binary bits are easy to translate into light pulses. These pulses can travel 60 miles before experiencing any degradation. To broadcast data thousands of miles left, these pulses pass through visual amplifiers that amplify their signal so that no data is lost.


How do fiber-optic cables transmit data with greater bandwidth?
Fiber optic cables have a wide range of frequencies that can travel without loss of data quality compared to copper wire or satellite connections, offering significantly higher bandwidth capabilities than alternatives.

How do fiber-optic cables transmit data with higher security?
Hacking fiber optic cable is far more difficult and expensive than intercepting signals over a copper or satellite connection, making fiber internet access more secure.

Which is better fiber optic or copper? - fiber optic vs copper
Although the advantages of using fiber optic transmission far outweigh the disadvantages, its disadvantages should not be underestimated.
Difficult to Splice. Optical fibers are difficult to separate and scattering causes light loss in the fiber. They have a limited physical arc of cables. If you twist them too much, they will break.
Fragility -It is made of glass, which is much more delicate than electrical cables such as copper cabling. 
Can’t Be Curved -Transmission on optical fiber has to be repeated at long intervals. When just a few centimetres of radius curves are wrapped, the fibers can be broken or the transmission can be damaged.
Highly Susceptible
Fiber optic cable is a small and compact cable, and it is extremely sensitive to cuts or damage during installation or construction activities.
