Unlike what many may think, the medium is not a hollow tube. It is a rod with a small diameter that uses the properties of light to transmit information signals. It uses total internal reflection of light to propagate high bandwidth signals at the speed of light.
Fibre broadband uk comes in two main varieties, single mode and multi-mode transmissions. The single mode allows high speed transmission over long distances using only one signal. Multi-mode allows relatively shorter distance of transmission using several signals. The difference in distances is because the multiple signals interfere with each other as they travel.
These media require highly trained individuals to handle them. They are fragile and require expensive equipment to terminate them. This makes the cost of installation higher than that of copper ones.
There has been a joint effort by world countries to create a single worldwide network of communication lines using these cables. They lay cable lengths in the oceans and through the red sea that link up all the continents without use of satellites. The continents also have their own backbone cables that link each country to the global network.
Due to their high bandwidth, people requiring large data transmissions use these cable links for their purposes. Some of the main uses include for TV connections, local area networks and telephone lines. This technology is slowly phasing out traditional copper cables.
Most data networks used wireless links through satellites and radio waves. These require very expensive equipment in form of signal re-generators and repeaters. To remove these, people came up with these fibers that can transmit for longer distances with minimal interference.
The cables have a protective coat of rubber or other material. This protects it from physical damage in the environment it lies and also prevents signal and noise interference. This enhances accuracy of signals transmitted and thus reliability is enhanced. Many people use this technology to support backbone communications in Ethernet and multi-cast communications.
The companies that produce these transmission media have many employees specially trained for these jobs. They have to be careful in their work to produce products of high quality. These precise jobs are the cause of the high capacity and hence, it is very important that each employee undergo proper training.
The raw materials of the cables are mainly glass and thus cable manufacturers have to be near glass manufacturers. They easy supply of materials makes production of cables faster and easier. Fibre optic broadband is necessary to create hotspots with high-speed internet access. Many cities have houses and businesses with this technology. However, the technology is used in conjunction with others like wireless for end-point connections.
