In the past 20 years, communication systems have developed drastically in a small amount of time, as a result of the creation of Internet, the use of communication systems has been enhanced, allowing our modern technologies to function efficiently and fulfilling our needs as the industry grows. The industry is constantly looking for methods to increase the quality, quantity and velocity in the transfer of data. The following report will analyse the current modern techniques used in fibre-optic systems. Briefly examine the origins and history of lightwave systems. Followed by discussing the main techniques that are currently used within the design of fiber-optic, the main concerns regarding theoretical and design issues. Carrying on to discuss the advantages, disadvantages, possible risks and the possible solutions for those. To conclude on the future development of fibre-optic and how the mentioned techniques can be used in other systems. Literature review History background The origins of the use of light for communication purposes is very remote. In the past, mirrors, fire, smoke signals were used to communicate between the surrounding habitants of an important event such as
Communication has been a real asset to humankind by having the capacity to exchange data starting with one then onto the next. While numerous diverse structures exist, for example, gesture-based communication, talking, and non-verbal communication, it is telecom that has changed the world all through the last hundred or more years. The information transfers framework has three separate things with a particular end goal to transmit what will exhibited. Person begin by the source or transmitter, which is then put into a medium or correspondence line, and ultimately there is a sink, or beneficiary that the data is yielded
We benefit greatly the benefits of long distance communication, eating food from different parts of the countries without fear of spoilage, radiation treatment, and heating up food in a matter of minutes, and a myriad of other wonders all do the wonders of waves, be they sound waves as well as light waves. In this timeline, we will look at all of the different light waves, their history, and their benefits.
Transferring data between computer systems in volume is easy, in a matter of a few minutes it is possible to transfer millions of records
Communication among humans has always been there from the very start and the modes of communication developed as they moved further apart from each other. The early centuries records of people messengers who were used to transport messages as fast as they could. Pigeons were trained to transport messages. There is indications that Heliographs were used for serious signaling purposes. A code book was issued by the 16th century for British navy including flags with different meanings to communicate during the war. Then there were watchman who had the responsibility of data transmission. There were various ways of transmitting data without the help of electricity (Holzmann and Pehrson, 2015).
“In the nineteenth century, light beams were used for short-haul communications, particularly in military contexts. Very detailed messages could be transmitted by a coded sequence (Morse code) of blinking lights from sender to receiver. Again, this was effective over limited distances and provided a quiet, yet visible means of communication. Drawbacks included limited
The existing setup make use of the full spectrum of the visible light for data transmission. But the components having shorter wavelength undergo scattering easily. Hence we also propose a system wherein only the spectrum having longer wavelength are used for data transmission in addition to the generally used white light for ambiance.
Even though data transfer techniques have advanced significantly, internal business system configurations need to be developed to allow for these transfer techniques to be used efficiently.
Consumer Electronics Bus (CEBus), a standard proposed by the Electronic Industries Association, is based on the concept of Local Area Networks (LAN’s). CEBus based products consist mainly of a transceiverwhich implements spread spectrum technology along with a controller to run the protocol. The given protocol standards are for radio frequency, twisted pair, power line communication and a number of other networking methods. The CEBus PLDT standard specifies that a binary digit is represented by how long a frequency burst is applied to the channel i.e, a binary ‘1’ is represented by a 100 microsecond burst, whilst a binary ‘0’ is represented by a 200 microsecond burst. CEBus transmission rate varies with how many ‘0’ characters, and how many ‘1’ characters are transmitted. The CEBus standard specifies a language of object oriented controls including commands for volume up/down, temperature up one degree, etc. Due to the high noise level of power line channels, data should be transmitted via short frames, which is assured by the use of the spread spectrum technology. CEBus protocol uses a Carrier Sense Multiple Access/Collision Detection and Resolution (CSMA/CDCR) protocol to avoid data collisions. CEBus is a commercially owned protocol, and thus attracts registration fees.
Using the internet allows you to transfer information around the world with in seconds. Whenever an email, picture or web page travels across the internet computers break the information into smaller pieces called packets. When information reaches its destination packets reassemble in its original order to make it understandable to receivers.
The means of communication has also changed significantly such that messages are sent and received instantly between the communicating parties. In addition, new products of different functionalities and shorter lifecycles have been developed with the help of advanced technologies.
Advancements in the information technology sector have brought many benefits to the people all around the world. Today with computer networking, we can chat, speak and see each other over a long distance. Data communication refers to the transmission of the digital signals over a communication channel between the transmitter and receiver computers. Communication is possible only with wired and wireless connectivity of the computers with each other.
From the beginning, efficiency and speed in the telecommunications industry has advanced at a fast pace owing to fiber optic technology. In 1979, AT&T filled the telecommunications industry with revolutionary ideas by developing a mode for data transmission using a light, called fiber optic cable. This mode produced a bandwidth of 44.736 Mbps and could multiplex 672 trunk circuits on one fiber alone (Cole, M. 2000). However, this development was merely the start of a huge extension to telecommunications, something that would transform the industry constantly.
This paper presents a brief introduction on the basics and applications in fiber optic sensors. This innovation is one of the quickest developing advances in the cutting edge science. Various investigates have been directed in past decades utilizing fiber optic sensors with diverse strategies. Power, stage, and wavelength based fiber optic sensors are the most generally utilized sensor sorts. In this paper, a review of fiber optic sensors and their applications are exhibited. Different sorts of fiber optic sensors and their applications are discussed.
The great growth in user’s demand for bandwidth due to today’s network applications stir the competition between network carriers. FSAN began studies to access needs in late 2010, they concluded that there is a great gap between user needs and the bandwidth offered by the 10 gbps capable Passive Optical Network (10G-PON known as XGPON) technologies. A system proposal for Next Generation- Passive Optical Network (NG-PON2) stage 2 was commenced in 2011. Among other solutions Time and Wavelength Division Multiplexing Passive Optical Network (TWDM-PON) technology was recommended at the April 2012 meeting as a primary solution to design and implement NG-PON2 [1]. This network design achieves
For years, infrared LED has been merely a system for piping light around corners and into the inaccessible places to allow the hidden to be lighted. But now, infrared LED has evolved into a system of significantly greater importance and use. Throughout the world, it is now being used to transmit voice, television and data signals as light waves. Its advantages as compared with conventional coaxial cable or twisted wire pairs are manifold. As a result, millions of dollars are being spent to put these light wave communication systems into operation.
