This year, the safe city project has been vigorously promoted, more and more video surveillance points, and the demand for optical transceivers has also increased. In terms of the first half of the year, the company's optical transceiver shipments are still considerable. With the development of high-definition video and the improvement of people's safety awareness, digital high-definition video will gradually replace traditional analog video. The upgrading of analog monitoring points in cities across the country will be a general trend. Both the high-definition video industry and the optical transmission industry are a rare opportunity for development.
The optical transceiver in video surveillance is a transmission device in an optical communication system, and mainly performs photoelectric conversion and transmission functions. It is widely used in telecommunication, power, monitoring, industrial control, video transmission and other functions, and has a wide range of applications in various industries. Often referred to as an optical transceiver refers to an optical transceiver used by a monitoring system to transmit comprehensive information such as video, data, Ethernet, and audio. Mainly analog optical transceivers and digital optical transceivers. The transmission-based medium differs in the single-mode optical transceiver and the multi-mode optical transceiver. The digital optical transceiver digitalizes the image, voice, and data signals to be transmitted, and multiplexes these digital signals, so that the multiple low-speed digital signals are converted into one high-speed signal, and this signal is converted into an optical signal.
At the receiving end, the optical signal is restored to an electrical signal, the restored high-speed signal is decomposed to the original multi-path low-speed signal, and finally these data signals are restored to images, speech, and data signals. The analog optical transceiver is to amplify or frequency modulate the signal to be transmitted and then convert the modulated electrical signal into an optical signal. At the receiving end, the optical signal is reduced to an electrical signal, and the signal is then demodulated to restore the image, speech or data signal. Digital optical transceivers have high transmission signal quality, and do not have the disadvantages of analog FM, phase modulation, and amplitude modulation when the optical transceiver multipath signals are transmitted in the same way, and are subject to serious environmental impact, poor transmission quality, and poor long-term operating stability. Therefore, digital optical transceivers will gradually Replace the analog optical transceiver. Currently in the areas of highways, transportation, electronics, surveillance, security, industrial automation, electricity, customs, water conservancy, and banking, optical video, audio, data, Ethernet, and other optical transceivers have begun to be widely used.
