Application Development of Video Optical Terminal

In the current digital era, various types of digital transmission methods are slamming into the market. At the same time, video optical transceivers are also grabbing the share of traditional wire rods and extending their tentacles to a wider area. Optical transceivers are no longer just a long distance away. Synonymous with transmission, in order to pursue better transmission results, more convenient on-site construction, and even lower system cost, people first think of optical transceivers. From the point of view of industry applications, it also explains the future development of video optical transceivers for us. Then this article will study the application development of video optical transceivers from six application fields.

1. Intelligent transportation and expressways lead the high growth rate of intelligent transportation and highways have occupied the first and second place in the growth of optical transceivers for a long time. Since the 1990s, with the acceleration of China’s industrialization process, a large number of population has flooded into the country. In cities, traffic problems have become increasingly prominent. In order to ensure the normal operation of urban transport, cities such as Beijing, Guangzhou, Tianjin, and Shanghai have all established urban traffic monitoring networks. In the urban road monitoring, the optical transceivers are mainly used for traffic statistics of city intersections, switching of traffic signals, capture of illegal vehicles, and monitoring of traffic accidents. It is responsible for uploading these video information to the traffic monitoring command center to ensure the normal operation of the city traffic. The highways are mainly involved in the construction of new projects and the upgrading of old equipment. With such a large-scale construction or transformation, the demand for products is naturally quite considerable. In addition, urban security surveillance has also become a bright spot for people's attention (of course, intelligent transportation should belong to the scope of the safe city); and industrial and mining companies, stadiums, and prisons, detention centers, etc., the demand for optical transceivers is also very significant increase, become the next Optical transceivers are the fastest growing emerging markets.

2. New highlights of urban security, public community monitoring and security monitoring: Since the establishment of Safe City, urban public security and public community monitoring have become one of the biggest highlights of China's security industry. Looking across the country, Beijing, Shenzhen, Guangzhou, and other places are gradually accelerating the pace of construction. As of the end of 2007, if the average investment for each city is 100 million yuan, the total investment for monitoring systems in 22 pilot cities across the country will be at least 2.2 billion. Because urban security monitoring involves the staged investment process, in fact, the amount of money used by many cities for urban security monitoring is far more than 100 million yuan. In the entire country, only one area of ​​urban security monitoring has brought the video surveillance market. Unpredictable business opportunities, while the use of video optical transceivers as a means of transmission accounted for more than 50% of the involved programs.

3, industrial and mining enterprises, frequent occurrence of mine accidents to monitor the monitoring of new demand for mines and mines are generally more decentralized monitoring, the environment is more complex, and many factories and mines in the range of up to tens of kilometers, therefore, the use of optical transceivers not only solve the problem of long-distance transmission , But also has a good anti-interference, can guarantee the effect of image transmission. It is out of these advantages that the industrial and mining enterprises have always been a field in which the optical transceivers are used more often. In addition to the existing advantages of optical transceivers, the frequent occurrence of coal mine safety accidents in recent years has also contributed to the increase in the demand for optical transceivers. In order to strengthen coal mine information construction and ensure coal mine safety, at the end of June 2006, at the National Coal Mine Digital Remote Monitoring System for Video and Telephone Conference, the national safety supervision department imposed a hard regulation on coal enterprises: by the end of 2005, the Gas, coal and gas outburst mines should all establish and improve safety monitoring and control systems. Moreover, the former state-owned key coal mine enterprises are required to implement the internal networking of the Mining Bureau (group company); the state-owned local coal mines and township coal mines must be networked within the county (district) area. Due to the special nature of coal mine environment, there are some special requirements for optical transmitters. For example, the equipment is required to be able to prevent explosions, prevent leakage, prevent long-time flooding, and even adapt to low voltage and the like. At present, for the explosion-proof requirements of coal mines, some manufacturers have developed dedicated downhole optical transmitters. This type of optical transmitter can transmit multiple digital non-compressed audio and video, pure 100M Ethernet signals, multiple telephone signals, and multiple control data signals through a single optical fiber. And multi-channel alarm signals, etc., are very suitable for use in coal mine safety monitoring systems.

4. Stadiums to Meet the Olympic Economy With the rapid development of China's economy, more and more influential activities, such as large-scale sporting events or international conferences are held in China. In order to ensure the smooth development of large-scale activities, security has become an important part of the overall system engineering construction, and security monitoring needs have become increasingly evident. According to the information released by the Beijing Organizing Committee for the Olympic Games, the security expenditure for the 2008 Olympic Games in Beijing amounts to 300 million U.S. dollars. Sports venues are very crowded places. There are a lot of monitoring points. In order to protect the safety of everyone, the monitoring requirements are relatively high, so the images should be very clear and real-time. The biggest advantage of optical transceivers for video transmission is that there is no bandwidth problem, which just satisfies the above special requirements. Therefore, it also has a lot of room for development in sports stadium monitoring.

5. Prisons and Detention Centers, Building Digital Prisons In today's high-tech digital development, "multimedia, digital, and all-round" are the new requirements of prisons for surveillance systems. In addition to the internal management of prisons, in general, relevant departments at or above the provincial or municipal level need to be well aware of the situation of each prison so as to avoid major accidents such as the escape of prisoners. Therefore, uploading images in a timely manner is an important aspect of the prison. The use of optical transmission, you can upload video information to dozens or even hundreds of kilometers of monitoring and management center. It is understood that in order to make plans for the future of laborers, many prisons now provide prisoners with certain workplaces to cultivate their labor skills and employability. In order to ensure that labor facilities and labor tools are not damaged, these sites also need to install a large number of monitoring equipment and video transmission equipment. Some engineering companies suggest that in prisons, the fewer the optical fiber lines are laid, the better, so as not to be vandalized.

6. Other applications In addition to the above-mentioned several obvious growth areas, the application of optical transceivers in other markets is also gradually popularized. With more and more integration of optical transceiver services, optical transceivers not only have video interfaces, but also have Ethernet services, audio service interfaces, and so on, and their application areas will also be more abundant. It can be expected that, in the present and the next few years, the optical transceivers will show different degrees of growth in government departments, financial institutions, oil fields, airports, ports and other fields.
