What is the Advantage of Network Cabling?
Networking is a word that has become synonymous with computers. With computers being a part of everyday life, wherever you go you are sure to find a computer installed. And in big organizations where there are innumerable computers, a good network cabling system is very essential for smooth running of business. Data cables used in networking are the only means through which data can be shared between various computing devices.
It is not a simple task to build a proper network cabling structure. Apart from service cables various other software and hardware devices are used such as Network Interface Cards (NICs), hubs, routers, bridges, switches etc. Some of the hardware components used for interlinking devices in networking are Ethernet network cables, optical fibers, wireless LAN, power communication etc. And when we speak of networking, structured cabling is one of the most sought after and effective means of building a networking infrastructure. There are various advantages of installing a proper networking system;
Types Of Voice Cables And Their Functions
Before going through this article, you might be thinking that what is voice cabling? However, after reading this article thoroughly, you will be fully aware of this type networking structure. It is done in homes, offices, and residential as well as commercial complexes. Voice cable enables basic telecommunications systems such as fixed line phone lines, modems, or analog lines. These wires are made of copper and fiber, which help in transmitting data across long distances very quickly. Moreover, these cables are increasingly designed in a certain manner so that they can transmit huge amount of data at lightning fast speed.
Nowadays, there are various types of voice cables, which are easily available in the market, as many new varieties have been developed in the past few years which abide with the national and global communication technology standards.
CAT-1 – This was an ordinary kind of fixed line cable, which is no longer accepted by the Telecommunication Industry Association. This was used for installing basic telephone communication system.
The History of Cabling
The Beginning
We tend to think of digital communication as a new idea but in 1844 a man called Samuel Morse sent a message 37 miles from Washington D.C. to Baltimore, using his new invention ‘The Telegraph’. This may seem a far cry from today’s computer networks but the principals remain the same.
Morse code is type of binary system which uses dots and dashes in different sequences to represent letters and numbers, modern data networks use 1’s and 0’s to achieve the same result. The big difference is, that while the telegraph operators of the mid 19th Century could perhaps transmit 2 or 3 dots and dashes per second, computers now communicate at speeds of up to 1 Giga bit, or to put it another way, 1,000,000,000 separate 1’s and 0’s every second. Not long after Morse’s Telegraph, a French inventor called Emile Baudot developed a printing telegraph machine which used a typewriter style keyboard, this allowed virtually anyone to send and receive telegraph messages. Baudot used a different type of code for his system because Morse code didn’t lend itself to automation, this was due to the uneven length and size of bits required for each letter. Baudot used a five bit code to represent each character, this would normally only give 32 possible combinations (00000 to 11111 = 32). It clearly wasn’t enough for 26 letters and 10 digits but he got around this problem by using two ‘shift characters’ for figures and letters, which performed the same sort of function as a typewriter shift key.

Fibre Optics
The installation and termination of optical fibers used to be regarded as somewhat of a ‘Black Art’ but with standardization and easier terminating techniques this is no longer true. A basic knowledge of the subject, together with a quick lesson and some practice can get you started in fibre optics, but to really understand the subject and gain full in-depth knowledge will require some formal training.
There are lots of Fibre Optic training companies offering recognized qualifications and a quick search on the net should find one in your area.
If you are in the UK, Optical Technology Training Ltd offer several different courses to choose from including a City & Guilds qualification.
There are also hundreds of books on fibre optics and a search on the Barnes and Noble web site will find nearly 600 titles. Without reviewing them all it is difficult to know what to recommend, but two of the best sellers in this category seem to follow on quite nicely from this page without getting too involved with mathematics. The two books are the Introduction to Fibre-Optics by John Crisp and
Understanding Fiber Optics, Third Edition by Jeff Hecht.
Right, lets get on with the lesson
First a bit history
In 1870, John Tyndall demonstrated that light follows the curve of a stream of water pouring from a container, it was this simple principle that led to the study and development of applications for this phenomenon. John Logie Baird patented a method of transmitting light in a glass rod for use in an early colour TV, but the optical losses inherent in the materials at the time made it impractical to use. In the 1950′s more research and development into the transmission of visible images through optical fibres led to some success in the medical world, as they began using them in remote illumination and viewing instruments.
