Normally internet connections use copper wires to carried electrical signals. DSL and coaxial cable networks are major internet setups. Due to resistance of copper against electricity, signals decrease with the length of wire. A signal booster is required after every 100-meter (932.8-ft.) distance
In optic fiber network a hollow tube that carries internet signals as light.
Light is faster than electricity hence while using fiber optic has various benefits.
It has greater bandwidth and can cover greater distance than copper.
There is very little signal loss during transmission
Data can move at higher speeds and greater distances
Copper wires radiate data (as electromagnetic signals) hence there is a possibility to access data without having physical access to copper cable. Fiber optic cable doesn’t radiate signals and is extremely difficult to tap. If the cable is tapped, it’s very easy to monitor because the cable leaks light, causing the entire system to fail.
Fiber optic cables have glass core and there is no electricity flow in it, data is transmitted as light, which makes it immune to electrometric interference and radio-frequency interference (EM/RFI), crosstalk, impedance problems etc.
Fiber optic cable does not heat up and can be safely sub merged in water.
