The process of urbanization in China is stimulating the development of the optical security security market. With the longest-running Beijing-Shanghai high-speed railway in the world about to be opened and operated, and the Wuhan-Guangzhou high-speed rail that is already in operation, the light rail of the Pearl River Delta is all showing signs of urban traffic. The construction will greatly stimulate the demand of the optical transceiver market.
First, digital optical transceiver Digital optical transceiver is to baseband analog video, audio, data for high-resolution digital, converted into high-speed digital stream optical signal, through the launch of the optical transceiver for transmission, and then through the other end of the receiving optical transceiver for receiving, demultiplexing, It is restored to a digital signal and then restored to analog video and audio through digital analog conversion (A/D conversion).
There are mainly two types of digital video optical transceivers: one is a non-compressed digital video optical transceiver and the other is a digital optical transceiver using image encoding compression. Digital transmission of light without compression can guarantee real-time and image clarity. When the user's optical fiber resources are sufficient, and emphasize the need to pay attention to image quality, non-compressed video signal transmission is the best choice. Due to the use of image compression technology, it can greatly reduce the signal transmission bandwidth.
Second, the light-end unit network is more convenient in the telecommunications exchange platform is increasingly perfect conditions, the network-based video transmission applications more flexible, Optical Multiplexer also needs to improve access to multi-service capabilities, large-scale networking applications. The multi-service video optical transceiver can provide a comprehensive optical transmission platform integrating video, audio, data, telephone, Ethernet and other service interfaces. It not only completes data transmission, but also realizes matrix and management functions. The networking application is very flexible.
With the extensive use of optical transceivers, the management of optical transceivers is also urgently needed. In response to this situation, many manufacturers have developed network management systems. Guangzhou Post specializes in the production of optical transceivers. Ring-type optical transceivers not only use advanced network management technology in hardware and software design, but also have advanced features in product structure and structure. The network management type optical transceivers adopt a modular design method. The functional module is the basic unit of the equipment. The functional module is connected through the backplane bus to complete various signal transmission functions required by users.
Third, urban rail transit into the main battlefield with the development of urban traffic and highway construction in China, the monitoring system in the equipment requirements are getting higher and higher, because the optical fiber transmission has a large bandwidth, transmission distance, anti-jamming advantages is widely used. Due to its many transmission advantages and the drastic increase in market demand in recent years, optical transceivers have significantly reduced the cost of optical cables and have entered a relatively benign industrial development track.
In the “Safe City†construction that began around 2008, Optronics has almost become the standard configuration, allowing optical manufacturers to usher in a “Golden Ageâ€. At present, safe cities, urban intelligent transportation, highways, and urban rail transit projects are the major markets for optical transceivers.
According to the forecast of authoritative agencies, the investment in China's urban rail transit market will reach 415.9 billion yuan in 2010-2015, with an average annual compound growth rate of 13.8%, of which, rail transit will be at least 2-3 billion yuan, and the annual domestic intelligent transportation system will be about The scale of investment of 20 billion yuan, video surveillance products accounted for about 16%, the annual new market demand is about 3.2 billion.
