There are many advantages to using fibre-optic cables, particularly over longer distances.
Faster (Can carry more information) - Fibre-optic cables can carry more information relative to the size of the cable than copper or coaxial cables. This is because light is faster and more efficient than electricity for carrying information.
Less expensive - Several kilometres of optical cable can be manufactured at a cheaper cost than equivalent lengths of copper wire or coaxial cable. This reduces the costs for cable providers, which leads to cheaper prices for customers of subscription television or broadband internet.
Less signal loss - Signal loss, or degradation, means the reduction of quality within a transmitted signal. Signal loss on a phone line results in static; on television, it can cause the 'snow' effect on the screen. For the internet, degradation means information is lost and has to be resent, slowing down the connection. Fibre-optic cables suffer less signal degradation than copper wire or coaxial cable, particularly over long distances. This leads to clearer sound and pictures, and faster transmission speeds on fibre-optic networks.
No interference - Unlike the electrical signals used in copper and coaxial cables, light signals from one strand of a fibre-optic cable do not interfere with other strands nearby. This means the strands can be bundled tighter together to save space. It also means there is even less signal loss.
Fibre is thinner - Each optical fibre can be smaller in diameter than individual copper wires, meaning more can fit in a smaller space and be bundled together into a cable. This allows more information to be sent through each cable and reduces the need to lay additional cables, and cuts down the size and weight of the cables when laying them over great distances and under water.
Use less energy - Because there is less signal loss, lower-power transmitters can be used to send information through fibre cables than for copper cables where high-voltage electrical transmitters are needed. This reduces cost and maintenance, saving money for customers.
Less risk of injury - Because no electricity is sent through these cables, there is no risk of electrocution or burns when handling or accidentally cutting through fibre-optic cables. There is also less risk of the cables themselves causing fires.
Flexible - Fibre-optic cables can be twisted, tied into knots and otherwise flexed without a major risk of breaking the cable. Copper and coaxial cables are less flexible and must be handled with greater care. Fibre-optic cables have proven very useful in other sciences such as medicine, where cables can be used to take pictures inside living bodies and in Plumbing and engineering where fibre cable cameras can be used to inspect narrow pipes or other hard-to-reach places.
Fiber Optics are unable to be tapped like radio frequencies. It is capable of high speeds and full duplex. Light is modulated and sent through them.
Some advantages of free space optics are lower costs, no fiber optics cables to run and no expensive rooftop layouts and installations. Also, the system may be upgraded in an easy manner without an RF license.
No, fiber optics are a transmission medium.
It is used by cable going up the anal and lighting up the inside.
Firstly, a fiber optic cable transmits light from one end of the fiber optic cable to the other end. You can kind of think of the fiber optic cable as a long tube. The way in which light travels from one end to the other is that it gets reflected off the inside parts of this glass or plastic tube by a physical phenomenon known as: Total Internal Reflection. Refraction of light only occurs when light travels from one medium to another. For example, when light travels from air to water, from water to air, from water to oil, etc. In other words, in terms of fiber optics, the only way light will get refracted is if it passes through the glass or plastic tube. But if this happened, then the light will exit the fiber optic cable as it travels from one end of the cable to the other end, and the light would not be properly transmitted, defeating the purpose of fiber optics. In other words, light should be reflective rather than refractive in fiber optics in order for light to be effectively transmitted from one end to the other end of a fiber optic cable.
No, fiber optics are cables ran from underneath the ground. The weather will not affect it.

Fiber optics is used for long distance communication due to its various advantages..
There are many great websites where you can purchase fiber optics cable. One great website is http://www.cablesplususa.com/.
Three ways that you can use fiber optics are: Cable Television, Computer Networking, Electronics Engineering
Cable internet providers and Verizon VIOS use fiber optics to send their internet to their users.
Yes, people speculate about 25 to 30 years. They even run fiber optics through the ocean, fiber optics is cutting-edge.
When used in terms of fiber optics, cable pulling is the act of pulling cables through wires while installing fiber optic services to a building or neighborhood. Some cable pulling can be done by hand and some requires special tools of the trade such as pulling grips.
By using Fiber Optics, we can achieve 100Gbps.
This one is very easy. Fiber optics are the future, and everything else is just old fashioned. You will be able to get more done with fiber optics than with anything else.
