An optical fiber is a glass or plastic fiber designed to guide light along its length by total internal reflection. Fiber optics is the branch of applied science and engineering concerned with such optical fibers. Optical fibers are widely used in fiber-optic communication, which permits digital data transmission over longer distances and at higher data rates than electronic communication. They are also used to form sensors, and in a variety of other applications.

The operating principle of optical fibers applies to a number of variants including multi-mode optical fibers, single-mode optical fibers, graded-index optical fibers, and step-index optical fibers. Because of the physics of the optical fiber, special methods of splicing fibers and of connecting them to other equipment are needed. A variety of methods are used to manufacture optical fibers, and the fibers are also built into different kinds of cables depending on how they will be used.

What are the reason's for not having a faster internet in america?

Is it a security threat? Not being able to detect the amount of information!

Here is the real answer, not a made up one, not what I think, and not something I heard "sometime" from "someone".

Countries like China, India, and Thailand have fiber optic networks because the networks they are putting in aren't replacing old ones, they are brand new. These countries previously had very limited communications infrastructure. When the time came they put in fiber optic because in the end it's more reliable, cost-effective, and can handle a lot more data.

In the case of COX, they handicap their modems programmatically to perform at lower speeds. Business clients get the same modems, pay more and get faster download and upload speeds. It's all about economics and sales.

However, some telecom providers are pushing for legislation to control your bandwidth even further. This way they will allow higher speeds for companies that pay them and lower for those that don't. If you care about your internet speed the following site is definitely worth a look: http://www.savetheinternet.com/

It all comes down to economics. China's work force is moving at tremendous speeds because the government has suppressed wages and there are a billion people in China. Because of that, it is easier to install and they can do it for less (because they don't pay their workers much) to install it.

Take the same job in America and you have to pay someone like 4 times the price to install it, with a work force that is much slower, spend 10 times as much to train the person and then give it to only about 80% of the 300 million person population that uses the Internet.

Believe me, if the US could install and make changes as easily and cheaply as China can do it, then everyone have fiber. The US is getting beat in lots of markets, not just IT. Look at automotive, aerospace, transit, and raw material production. Us is not the top in any of them.

It is somewhat of a security threat since we can't keep up with the rest of the world. However I think once we are on the bottom of the totem pole economically, we will be less of a target since we won't have much power to do things.

Hope this helps answer your good question.

You can use a couple of Wireless Access Points or Wireless Bridges, using Yagi directional antennas to create a bridge down the garden to maintain signal strength for Wireless N. Don't buy commercial antennas, buy Amateur Radio 2.4GHz Yagis, as they are much cheaper if you take the trouble to look. This will probably cost less than 100ft of ruggedised fibre optic or ethernet cabling, and involves no digging, plus no-one is likely to cut the connection while gardening. You can run Gigabit Ethernet to the Wireless N Bridge / Access Point, and with Yagi Antennas probably maintain 600Mbit over the wireless link. Ethernet and Fibre, unless you use expensive cabling, will likely be 100Mbit max.

Probably because the communication companies have decided it simply wouldn't be cost effective to install fiber optics all over the country.

North america is not as 'advanced' and sophicistated as we would like to think.
China/japan/india are excelling faster, because politicians are not holding up the system. to make any major changes we have to go through politics, where people in their 40-50 make choices.. and they don't even use the internet or know much about it.
The asian contries, have hardworking people that want to see change, they want to be better then the west..
Although some parts of the US have FTTC - fiber to the curb, but it's only a few trial runs by big companies.. and they cost a fortune to have.

because in china the electricity developed earlier than in another countries.and there are very much people like America
