Why fiber optics cable is more secure the other copper cables ?

They say that fiber optics cable are more secure than other copper cable such as coax, UTP, but why ?

Fiber cables does not radiate signal and is very difficult to extract data from it.if it is then it is very easly seen because it leaks light

which cause whole system to fail.

The main reason is that coax cables uses electromagnetic waves to transfer the signal which might experience to pick up unintended signals which cause interference. But optical fibers use light to transfer signal.

in fiber optics the data transfer via light pulses which propagate inside the inner section of the cable so they   have no way to radiate out side the cable while in copper or any  metal alloy cable there are electromagnetic   radiation of signal  due to the SKIN effect  thus it can be easily intrusion  to the data transferred by the cable

Fiber cble use light to send and recieve data with high speed it does not use electro magnetic waves

Security depends on the encryption method used. Can tape data simply from Coaxial cable but can't tape data from optical fiber without a notce. The main advantage of optical fiber is broad band and free from interference.

1. Fiber optic transmission is faster.

Fiber optic versus copper wire transmission can be boiled down to the speed of photons versus the speed of electrons. While fiber optic cables don’t travel at the speed of light, they come very close—only about 31 percent slower.

 

2. Fiber optic transmission results in less attenuation.

When traveling over a long distance, fiber optic cables experience less signal loss than copper cabling. This is called low attenuation. Copper cables can only transmit information up to 9,328 ft due to power loss, whereas fiber cables can travel between 984.2 ft to 24.8 miles.

 

3. Fiber optic cables are impervious to electromagnetic interference (EMI).

Copper wires, if not properly installed, will produce electromagnetic currents that can interfere with other wires and wreak havoc on a network. Fiber optic cables, unlike copper cables, do not conduct electricity.

 

4. Light cannot catch on fire.

An added benefit of fiber optic cables is that they are not a fire hazard. This can also be attributed to the same reason that the cables do not produce EMI—there is no electric current traveling through the core.

 

5. Fiber optic cables do not break as easily.

This means that you will not have to worry about replacing them as frequently as copper wires. Even though the fiber is made of glass, copper wires are more prone to damage than fiber optic cables are.

It 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. If an attempt is made to break the physical security of your fiber system, you’ll know it.

In optical fibres signals are transmitted as light signal inside a greatly protected by multiple layers being core, cladding, buffer,etc. ... Whereas in normal copper conductors, the electromagnetic interference (EMI) is there which can induce some voltage and hence current in the wires thus corrupting the signal

The Top reason to be it more secure comapring with other cables as Coaxial Cables ... etc, is not have electromagnatic field becuase it is use the light to send and receive the data and have very high speed.

 

It is the best one.

Your data is safe with fiber cable. It 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. If an attempt is made to break the physical security of your fiber system, you’ll know it.

Fiber networks also enable you to put all your electronics and hardware in one central location, instead of having wiring closets with equipment throughout the building.

simply because there is no electromagnetic radiation.
