In our study and work, we often see papers. Thesis is a kind of reasoning article that conducts research in various academic fields and describes academic research results. I believe many friends are very upset about writing papers. The following is my paper for you, discussing the advantages and disadvantages of optical fiber communication transmission technology and its application in modern communication. Welcome to read the collection.
With the development of communication technology, the birth of optical fiber has made a qualitative change in signal transmission. In today's information age, the complexity of communication network is constantly improving, which has laid a solid foundation for the development of modern communication. At present, the most widely used technology in communication engineering is modern optical fiber transmission technology, which greatly improves the reliability and transmission rate of communication transmission. By analyzing the advantages and disadvantages of modern optical fiber communication transmission technology, this paper discusses the application of optical fiber transmission technology in modern communication.
Keywords: optical fiber communication; Transmission technology; Application;
I. Optical fiber communication technology
1. Brief introduction of optical fiber communication transmission technology.
Optical fiber communication transmission technology is based on optical fiber, which has the advantages of long transmission distance, large communication capacity and little environmental pollution. Optical fiber can be divided into communication fiber and sensing fiber, which can shape, divide frequency and modulate light waves under different conditions. In practical application, optical fiber communication transmission technology has high light wave frequency. Compared with ordinary transmission mode, optical fiber has higher transmission quality and less loss.
2. The characteristics of optical fiber communication technology.
(1) has low construction cost and low loss. With the improvement of transmission technology, the loss of optical fiber transmission is decreasing. Optical fiber communication mainly uses timely manufactured insulators, which has the advantages of low cost and low loss compared with other types of optical fibers. There is no need to install loop and grounding in the construction process, and the insulation performance is good, which greatly reduces the construction cost.
(2) Large capacity. Compared with cable and copper cable transmission, optical fiber transmission loss is small and bandwidth is high. Through special technical means, the amount of information transmitted by optical fiber is expanded to realize long-distance and efficient transmission.
(3) The occupied space is small. The diameter of optical fiber is very small, the smaller the space occupied in the construction process, the less the construction tasks and post-maintenance and the less the maintenance time of optical fiber, which plays a very important role in the integration of communication systems.
(4) Good confidentiality and anti-interference ability. Timely optical fiber has good insulation and corrosion resistance. It has strong resistance to electromagnetic interference released by high-voltage lines and electromagnetic interference in natural activities and will not interfere with signal transmission. It is widely used in the military. Traditional radio communication is prone to the problem of radio leakage, with poor confidentiality, while optical fiber communication technology has strong confidentiality, which better protects the transmitted content.
Second, the application of modern optical fiber communication transmission technology
(1) single fiber bidirectional transmission technology. Now, changing the existing double-fiber bidirectional technology into single-fiber bidirectional technology can save energy more effectively and reduce the consumption of optical fiber. Single fiber bidirectional transmission technology is modulated by artificial signals in different frequency bands, and it is more suitable for access of optical fiber terminal equipment through technical improvement.
(2) FTTH access technology. That is, FTTH mainly adopts PON passive optical network and P2P communication scheme for transmission, and has an all-fiber and transparent optical access network mode, which provides strong support for the continuous acceleration of triple play. In order to meet the needs of consumers for communication technology, there must be fiber-to-the-home access technology. Although ADSL technology provides a good foundation in the field of information communication, it will be less and less used in future communication services, especially in conference TV, online games and HDTV digital TV.
(3) Application in electric power communication. The future development of power communication is mainly based on internal demand. Inside the power grid;
First, we must reduce costs;
Second, we should pay attention to the importance of communication, outside the power grid, first, we must face the changes in the market;
The second is to overcome the influence on the outside world. According to this requirement, it is necessary for electric power communication staff to improve their professional level and strengthen communication work to ensure the normal operation of electric power communication.
(4) Optical switching technology. Optical switching technology is an optical fiber transmission technology that exchanges optical signals in the process of information transmission. The traditional communication network is based on metal cables, and the lines for transmitting information and data exist in the form of electronic signals, which are exchanged through electronic switches. At present, the traditional wired communication network has been replaced by optical fiber communication technology, but the user terminal part adopts optical fiber transmission, and information and data exist in the form of optical signals. However, this technology is still an electrical signal exchange technology. Due to the immature optical switching technology, it is inefficient and costly to only convert optical signals into electrical signals and then transmit them as optical signals. Therefore, the research and development of large-capacity optical switching devices provides support for the realization of optical switching technology. However, because the large-capacity optical switching technology is not mature in small particle and low-speed signal exchange, the electronic switching technology can also be used for small particle signal exchange.
Third, the development trend of optical fiber communication technology
(1) intelligent optical network. The optical fiber communication mode in China is mainly transmission, but with the rapid development of computer technology, computer technology has further developed network communication technology. Information automatic discovery technology, system protection and recovery function and automatic connection control technology make more use of modern optical network technology and promote the intelligent development of optical network, which is also the main direction of communication field.
(2) Integration of optical devices. In order to promote the development of network communication transmission speed, the integration of optical devices is an important development direction to realize all-optical network. At present, the traditional ADSL broadband access can not meet the demand of information transmission, so we must first improve the performance of optical devices and improve the speed of information transmission. Therefore, the integration of optical devices is an inevitable development direction to promote the development of optical fiber transmission technology.
(3) All-optical network. All-optical network exists in the form of light in the process of signal exchange and network transmission, and performs electro-optical and photoelectric conversion when entering and leaving the network. In the traditional optical network system, electrical equipment is used at network nodes, and all light is formed between nodes, which affects the total capacity of optical fiber communication trunk lines. Therefore, it is an important subject to realize all-optical network. In order to realize all-optical network, optical conversion technology and WDM technology must be established to improve the transmission speed of network information and the utilization rate of network resources.
Conclusion:
Optical fiber communication transmission technology has become an important technology of information transmission in modern society. With the wide application of optical fiber communication technology in the field of information communication, large capacity, high speed and long distance have become our main goals. With the advent of the network era, we must understand the current situation, advantages and disadvantages of optical fiber communication transmission technology as soon as possible to promote the development of optical fiber communication transmission technology.
