What are optical communications and what are the industry trends? Optical communications?
Optical communication is a technology that uses light waves as an information carrier to transmit information through a transmission medium such as an optical fibre. Its working principle is that the transmitted information (such as voice) is converted into electrical signals at the transmitting end, and then modulated onto the laser beam emitted by the laser, so that the intensity of the light varies with the amplitude (frequency) of the electrical signal and is sent out through the optical fibre; at the receiving end, the detector receives the optical signal, converts it into electrical signals, and restores the original information after demodulation. Optical communication technology has the advantages of high speed, large capacity, low loss, strong anti-interference ability, etc. It is suitable for a variety of scenarios, such as inter-coastal islands, close distance remote control, and intra-vehicle communication.
The composition of optical communication system mainly includes the basic parts of optical transmission, optical reception and transmission optical path. Among them, the optical fibre cable is used for data transmission, and the optical module is applied to the optical communication equipment, which is the bridge connecting the optical communication equipment and the optical fibre cable. In addition, optical communication equipment is a communication device that provides the ability to transmit data traffic with large bandwidth, high reliability, and low latency using light wave transmission technology.
With the development of technology, the optical communication industry faces challenges and opportunities in many aspects. For example, the nine challenges facing key technologies for optical communications in the next decade include issues such as technological change not keeping up with the growth rate of business traffic. At the same time, China's optical fibre communication technology and products and equipment have been in the world's leading level, and has the world's largest and most complete optical communication industry chain.The optical communication industry in 2023 presents ten major development trends, including the development trend of 400G, all-optical network, C" L-band expansion and other key technologies.
