With the continuous maturation and perfection of technology, domestic optical transceivers are also making progress in terms of functions and performance. Such as the video AGC (automatic gain control, which automatically monitors the amplitude of the input video signal, dynamically adjusts the gain, so that the receiver outputs a standard 1Vp-p video signal) function. The technology upgrade is also reflected in the diversity of functions. For example, it can provide richer service interfaces, battery power-off alarms, character superposition, lightning protection and moisture protection, and device network management. It shows that the product is convenient for application upgrade and has fault pre-diagnosis. The system's video transmitter. The video optical transceiver technology upgrade is also reflected in the functional modular design. The main functions of the product, such as photoelectric conversion, video, data, audio and other functional modules are designed to be completely independent pluggable, and the signals involved in security are integrated into one. Optical transceivers.
Lightning protection design is also an important issue for the modern optical transceivers. Lightning protection needs to be considered on all external interfaces of the optical transceiver, not just the data interface, and all external interfaces such as video and audio and power input interfaces should also be considered. Otherwise, lightning strikes the device from the weakest link in many cases. Causes equipment damage.
In 2010, it became the first high-definition year for the surveillance industry, and the concept of 'HD' in the video-optical-drive machine industry began to rise. Frog Communication has launched a high-definition video optical transceiver that covers HDMI, DVI, SDI and other common interfaces. Our Olink company has also launched its own high-definition optical transceiver.
In the high-speed development of the optical transceiver industry, it is also accompanied by competition in technology solutions, the most important of which is the competition of network video solutions. The current optical fiber transmission scheme, in addition to the mere use of the optical end unit network solution, also includes the optical matrix, video codec + switch, Ethernet passive optical network (EPON) + video codec, UTN integrated service optical transmission Network and other programs. Different types of optical transceivers use different types and methods. For example, in order to cooperate with the construction of Ethernet passive optical networks, optical transceivers based on EPON technology have also begun to receive attention from manufacturers. Such products can reduce costs for projects with large-capacity front-end video access. The integrated digital optical transmission and switching system for integrated services can well solve the requirements of multi-stage transmission/exchange and management, and is a new technology platform for optical transceiver technology development. The system's products can also well support the access of various topological image distributions, such as star, chain, ring, and hybrid topologies.
The development period of the “Twelfth Five-Year Plan†will be a crucial period for the development of optical fiber broadband access networks. According to the country's development requirements, triple play, broadband speed increase, Internet of things, energy saving and emission reduction will all be the key directions for the development of optical fiber broadband access during the 12th Five-Year Plan period. The main tasks include: Actively promoting 10G passive optical network Commercial trials of new technologies such as (PON) and multiplexed passive optical networks (WDMPON) to meet the FTTH (FiberToTheHome, fiber-to-the-home) access of 100Mbit/s per subscriber, creating a global leading optical broadband access network; And develop technologies and products that can better integrate the Internet of Things, create a powerful access bearer network for the Internet of Things, continuously improve green environmental protection and energy-saving emission reduction technologies, and strive to make the power consumption of active devices in fiber access networks international Leading level.
In order to achieve higher access bandwidth, fiber-to-the-home (FTTH) promotion will bear the brunt. China Telecom plans to open 1 million lines of FTTH subscribers, and both China Mobile and China Unicom will also accelerate FTTH deployment. In the next few years, FTTH will surely usher in explosive growth, expand market demand, and help the optical fiber industry move forward. According to relevant statistics, with the full implementation of the “Broadband China Optical Network City†project, the planned addition of fiber-to-the-home (FTTH, ie access bandwidth of 100M or more) to 30 million households in urban areas in 2011 is “11. During the period of the "Five" period, cumulative coverage of 40 million households was achieved; Southern cities (including county seats) achieved full 8M access bandwidth coverage, 20M coverage rate reached 70%; 20M coverage rate of eastern developed cities and capital cities in the central and western regions reached more than 80%. In 2013, all home customers in southern cities (including county seats) can provide 20M access, and fiber-to-the-home coverage reaches 80 million.
At the end of the “Twelfth Five-Year Planâ€, Southern urban areas achieved full coverage of household and government-industry users' optical networks, and fiber-optic access to households exceeded 100 million, ranking the world leader.
The large-scale construction of fiber-optic broadband access networks by telecommunication operators has a wide range of impacts on professional security video optical transceiver manufacturers. Large-scale construction of fiber-optic broadband access networks provides good opportunities for optical transmission equipment and optical cable manufacturers. Comprehensive optical communications companies can gain access to this market and expand the market very well. The vast majority of companies that solely produce video optical transceivers have difficulty entering this market. On the other hand, the establishment of the world's leading optical fiber broadband access network in China will greatly promote the development of IP surveillance. This is beneficial to enterprises that produce optical-to-electrical converters (fiber MODEM), but it will result in video optical transceivers in the entire security monitoring system market. The proportion in the reduction. Video optical transceiver manufacturers, if combined with current IP video solutions, will provide users with a large-scale video integrated management platform based on fiber optic cable, which will take a more proactive position in the market competition.
At present, monitoring network front-end equipment will not fully adopt digital products in the short term due to a variety of reasons; secondly, analog video solutions have mature and economical advantages, and are particularly suitable for small and medium-sized monitoring projects; in addition, for projects built for use. It is still more convenient for maintenance and expansion to follow the previous fiber transmission scheme. So in these respects, the video optical transceiver still has a large application prospect.
The development of IP surveillance has a different view on the future market of optical transceivers. One is that with the acceleration of the IP process, the proportion of video optical transceivers in the entire security monitoring system is shrinking. However, there are different opinions in the industry that the optical transmission based optical fiber transmission optical disc market will not be affected since the transmission speed is unstable due to network bandwidth restrictions and the optical transmission compression technology will improve the future convergence of the two devices rather than the competition.
The integration of optical transceivers and other products is also a future development direction. Foreign companies have developed optical transmission cameras in the early years. In the past two years, domestic companies have also developed similar products. Take fiber optic high-speed ball as an example, the world's high-speed ball is the optical transmitter module to achieve high-speed ball on the circuit board.
As the price of optical fiber and optical transceiver core chips decreases, the use of optical transceivers becomes more and more widespread. Many security systems require better transmission technologies, and customer demands will be further diversified. Optical transceiver products will generally develop to multi-service integrated platforms. . In short, digitalization, multi-functionalization, intelligence, standardization, and integration are the current directions for the development of optical transceivers.
