Fiber Optic Cable We begin by asking Just what is a fiber optic cable? A fiber optic cable is a cylindrical pipe. It may be made out of glass or plastic or a combination of glass and plastic. It is fabricated in such a way that this pipe can guide light from one end of it to the other. 1.Fiber optic cables. The idea of having light guided through bent glass is not new or high tech. The author was once informed that Leonardo DaVinci actually mentioned such a means for guiding light in one of his notebooks. However, he has not been able to verify this assertion. What is known for certain is that total internal reflection of light in a beam of water - essentially guided light - was demonstrated by the physicist John Tyndall [1820-1893] in either 1854 or 1870 - depending upon which reference you consult. Tyndall showed that light could be bent around a corner while it traveled through a jet of pouring water. 2.Fiber optic cables. Using light for communications came after this. Alexander Graham Bell [1847-1922] invented the photo-phone around 1880. Bell demonstrated that a membrane in response to sound could modulate an optical signal, light. But, this was a free space transmission system. The light was not guided. 3.Fiber optic cables. Guided optical communications had to wait for the 20th century. The first patent on guided optical communications over glass was obtained by AT &T in 1934. However, at that time there were really no materials to fabricate a glass (or other type of transparent material) fiber optic cable with sufficiently low attenuation to make guided optical communications practical. This had to wait for about thirty years. 4.Fiber optic cables. During the 1960's researchers working at a number of different academic, industrial and government laboratories obtained a much better understanding of the loss mechanisms in glass fiber optic cable. Between 1968 and 1970 the attenuation of glass fiber optic cable dropped from over 1000 dB/km to less than 20 dB/km. Corning patented its fabrication process for the cable. The continued decrease in attenuation through the 1970's allowed practical guided light communications using glass fiber optic cable to take off. In the late 1980's and 1990's this momentum increased with the even lower cost plastic fiber optic cable and Plastic Clad Silica (PCS). 5.Fiber optic cables. Basically, a fiber optic cable is composed of two concentric layers termed the core and the cladding. These are shown on the right side of Figure 2-2. The core and cladding have different indices of refraction with the core having n1 and the cladding n2. Light is piped through the core. A fiber optic cable has an additional coating around the cladding called the jacket. Core, cladding and jacket are all shown in the three dimensional view on the left side of Figure 2-2. The jacket usually consists of one or more layers of polymer. Its role is to protect the core and cladding from shocks that might affect their optical or physical properties. It acts as a shock absorber. The jacket also provides protection from abrasions, solvents and other contaminants. The jacket does not have any optical properties that might affect the propagation of light within the fiber optic cable. 6.Fiber optic cables. The illustration on the left side of Figure 2-2 is somewhat simplistic. In actuality, there may be a strength member added to the fiber optic cable so that it can be pulled during installation. 7.Fiber optic cables. Fibre Optic Cable Strengthens The Communication Network Today, Fibre Optic Cable has become the prominent medium for high-speed transmission of large amount of data as well as for customized computer networking system. In spite of being expensive, most of the companies are installing optical cables to have un-interrupted and speedy transfer of information via wide range of computer devices. -- Fibre Optic Cable Strengthens The Communication Network 1. These days telecommunication applications of fiber-optic cable are widespread, ranging from global networks to desktop computers. Generally fibre cables are the bundle of thin glass threads (also called optical fibres) that are capable of transmitting any amount of data without any loss. These flexible fibres can be grouped together, and the resultant cabling network functions at superior bandwidths in comparison to other kinds of transmitting information media. Since these glass fibres go through low level of reduction and hindrance, they are extremely effective for various telephonic applications.-- Fibre Optic Cable Strengthens The Communication Network 2. Nowadays internet is a most prominent mode of communication, thus use of fibre technology ensures secure data transmission and networking in seconds with minimal loss of records. Many different types of telecom providers, like cable businesses and telephone service frequently uses these advance cable to have fast and better mode of communication. In-spite of the cost factor, most of the traditional telephone lines is getting replaced by cable optic technology for smooth, safe and easy transfer of information. -- Fibre Optic Cable Strengthens The Communication Network 3. Today, most conventional communications media including telephone, music, film, and television are reshaped or redefined by the internet, giving birth to VoIP service (Voice over Internet Protocol) and IPTV. With effective web network through modern fiber optic cabling structure, one can easily be able to watch live high-definition videos and movies, easily do video conference in real time, download large media files within moments and do a lot more things that are hard to do few decades before. -- Fibre Optic Cable Strengthens The Communication Network 4. Wireless internet and fiber optics offer out of the ordinary services that not only needed by large business corporate but also can be made use of at home. But due to lack of knowledge many people tends to relate the CAT cable as optical cables. Generally these cables are comprised of four copper wires that are twisted together, very similar to phone line. As compare to fibre cable, later uses electrical signals to transmit data from one source to other. These copper wires are cheap to install but they are insecure and have risk of data loss while transmitting through different mediums. Fiber optical provide much better bandwidth transmission capabilities and security as compare to these Ethernet network cables. -- Fibre Optic Cable Strengthens The Communication Network 5. Though expensive, optical technology is now being widely used as lan cable in most of the corporate offices and telecommunication industries. These are extremely useful for local-area networks or LANs which is confined to a relatively small area such as a single building or a group of buildings. With such large number of advantages, the time is not far when Fibre Optic Cable will surely outshine all types of networking cable system. -- Fibre Optic Cable Strengthens The Communication Network end.
