1. Immunity to Electromagnetic Interference
Although fiber optics can solve data communications problems, they are not needed everywhere. Most computer data goes over ordinary wires. Most data is sent over short distances at low speed. In ordinary environments, it is not practical to use fiber optics to transmit data between personal computers and printers as it's too costly. Electromagnetic Interference is a common type of noise that originates with one of the basic properties of electromagnetism. Magnetic field lines generate an electrical current as they cut across conductors. The flow of electrons in a conductor generates a magnetic field that changes with the current flow. Electromagnetic Interference does occur in coaxial cables, since current does cut across the conductor. Fiber optics are immune to this EMI since signals are transmitted as light instead of current. Thus, they can carry signals through places where EMI would block transmission.
2. Data Security
Magnetic fields and current induction work in two ways. They don't just generate noise in signal carrying conductors; they also let the information on the conductor to be leaked out. Fluctuations in the induced magnetic field outside a conductor carry the same information as the current passing through the conductor. Shielding the wire, as in coaxial cables can reduce the problem, but sometimes shielding can allow enough signal leak to allow tapping, which is exactly what we wouldn't want.
There are no radiated magnetic fields around optical fibers; the electromagnetic fields are confined within the fiber. That makes it impossible to tap the signal being transmitted through a fiber without cutting into the fiber. Since fiber optics do not radiate electromagnetic energy, emissions cannot be intercepted and physically tapping the fiber takes great skill to do undetected. Thus, the fiber is the most secure medium available for carrying sensitive data.
3. Non Conductive Cables
Metal cables can encounter other signal transmission problems because of subtle variations in electrical potential. Electronic designers assume that ground is a uniform potential. That is reasonable if ground is a single metal chassis, and it's not too bad if ground is a good conductor that extends through a small building. However, the nominal ground potential can differ by several volts if cables run between different buildings or sometimes even different parts of the same building.
Signal levels in semiconductor circuits are just a few volts, creating a problem known as ground loop. When the difference in ground potential at two ends of a wire gets comparable to the signal level, stray currents begin to cause noise. If the differences grow large enough, they can even damage components. Electric utilities have the biggest problems because their switching stations and power plants may have large potential differences.
A serious concern with outdoor cables in certain computer networks is that they can be hit by lightning, causing destruction to wires and other cables that are involved in the network. Certain computer companies are aware of this problem and trying to solve it by having protective devices for wire circuits to block current and voltage surges.
Any conductive cables can carry power surges or ground loops. Fiber optic cables can be made non-conductive by avoiding metal in their design. These kinds of cables are economical and standard for many indoor applications. Outdoor versions are more expensive since they require special strength members, but they can still be valuable in eliminating ground loops and protecting electronic equipment from surge damage.
4. Eliminating Spark Hazards
In some cases, transmitting signals electrically can be extremely dangerous. Most electric potentials create small sparks. The sparks ordinarily pose no danger, but can be really bad in a chemical plant or oil refinery where the air is contaminated with potentially explosive vapours. One tiny spark can create a big explosion. potential spark hazards seriously hinder data and communication in such facilities. Fiber optic cables do not produce sparks since they do not carry current.
5. Ease Of Installation
Increasing transmission capacity of wire cables generally makes them thicker and more rigid. Such thick cables can be difficult to install in existing buildings where they must go through walls and cable ducts. Fiber cables are easier to install since they are smaller and more flexible. They can also run along the same routes as electric cables without picking up excessive noise.
One way to simplify installation in existing buildings is to run cables through ventilation ducts. However, fire codes require that such plenum cables be made of costly fire retardant materials that emit little smoke. The advantage of fiber types is that they are smaller and hence require less of the costly fire retardant materials. The small size, lightweight and flexibility of fiber optic cables also make them easier to be used in temporary or portable installations.
6. High Bandwidth Over Long Distances
Fiber optics have a large capacity to carry high speed signals over longer distances without repeaters than other types of cables. The information carrying capacity increases with frequency. This however, doesn't mean that optical fiber has infinit bandwidth, but it's certainly greater than coaxial cables. Generally, coaxial cables have a bandwidth parameter of a few MHz/km, where else the fiber optic cable has a bandwidth of 400MHz/km. (These figures are just approximations and do vary from cable to cable!) This is an important factor that leads to the choice of fiber for data communications. Fiber can be added to a wire network so it can reach terminals outside its normal range.
The three main advantages are:
Speed - Fibre-optic cable is capable of transmitting data at a MUCH faster rate than copper cable.
Signal - Copper cable loses signal readily with length, and has to be boosted at regular intervals. The signal in Fibre-optic cable doesn't deteriorate nearly as much over distance and requires less boosting.
Capacity - Copper cable (using analogue signals) can only carry ONE signal at a time. Fibre-optic cable (using digital signals) can carry many data 'streams' as you just encode each stream so it gets to the right destination.
Optical data transmission is the name of the method of sending data through fiber optic cables. One optic cable can contain hundreds if not thousands of optic fibers. Simplex and half duplex systems use only one fiber to communicate. Simplex transmits only in one specific direction, while half duplex can send in both directions but not at the same time. If likened to a walkie-talkie radio, when the talk button is pressed it is transmitting out but will not be able to receive incoming transmission until the talk button is released. In a full duplex system, two fibers are used to communicate. One fiber is transmitting from point A to point B and the other fiber is transmitting back from point B to point A.
The advantages are the same as using symbols in writing to represent the words.

Yes, but it's at a different frequency than your internet. Chances are before you got FiOS your internet and phone still used the same fiber optic cable.
Fiber optic cable is not subject to EMI and RFI interference because it transmits data using light signals through glass or plastic fiber strands, rather than electrical signals through copper conductors. This makes fiber optic cable ideal for environments where high levels of interference are present, such as near power lines or in industrial settings.
To install fiber optic cable for home wiring, you will need to first plan the route for the cable, then carefully run the cable through walls, ceilings, or floors using appropriate tools. Next, terminate the cable ends with connectors and connect them to the appropriate devices. Finally, test the connections to ensure they are working properly.
Fiber optic cables offer advantages for high-speed data transmission due to their ability to transmit data at faster speeds over longer distances compared to traditional copper cables. They also provide higher bandwidth capacity, are less susceptible to electromagnetic interference, and are more secure as they are difficult to tap into.
Data travels through a fiber optic cable using light signals. These signals are sent through the cable as pulses of light, which represent the data being transmitted. The light signals bounce off the walls of the cable, allowing the data to travel quickly and efficiently over long distances.
