With the development of emerging technologies such as the Internet of Things, cloud computing, and artificial intelligence, the global data throughput continues to increase. In order to better support the development of future technologies, the market demand for high-speed broadband and data centers continues to grow, and 400G optical transceiver technology has become a hot topic. This article will discuss the technical principles and usage scenarios of 400G optical transceivers, and provide readers with ideas for in-depth understanding of the development in this field.
The 400G optical transceiver technology is realized based on the PAM4 modulation format. Among them, PAM4 is a 4-level pulse amplitude modulation method, and each symbol period can represent 2 bits of logic information (0, 1, 2, 3), that is, there are four levels in a time unit. Compared with the traditional NRZ system, the throughput of PAM4 signals doubles each time, which means that PAM4 can effectively improve bandwidth utilization. 400G optical transceiver technology is realized by multiplexing four 100G PAM4 optical signals on the same optical fiber, and finally reaches 400G transmission rate.
The key parameters of 400G optical transceiver technology mainly include: transmission distance, wavelength, optical power, sensitivity, operating temperature and power supply voltage, etc. There are mainly 8 types of 400G series optical transceiver s, and the transmission distance ranges from 100m to 40km. Among them, the wavelength of 400G single-mode optical transceiver s is usually 1310nm. For short-distance transmission, the transmission distance can reach 400m, and the wavelength is usually 850nm. In addition, in order to ensure the stability of signal transmission, there are some specific standards and requirements in terms of optical power, sensitivity, and temperature.
The application scenarios of 400G optical transceiver technology in the communication field mainly include: data centers, large-scale networks, cloud computing, artificial intelligence and other fields. All of these have extremely high requirements for data transmission rate and data processing capabilities, such as higher transmission rate, stronger scalability, better reliability, and lower latency. 400G optical transceiver s can meet these requirements!
In recent years, with the continuous emergence of emerging technologies, the global optical transceiver market has continued to grow. At present, the 400G optical transceiver market in China mainly includes the products of Eoptolink, InnoLight, HGtech, Accelink and other manufacturers. These manufacturers are also constantly promoting the research and development of optical transceiver technology and market layout. With the popularization of 400G optical transceiver technology, more and more domestic optical transceiver manufacturers are gradually increasing their 400G optical transceiver market share.
As an important part of high-speed broadband and data center applications, 400G optical transceiver technology will play an increasingly important role in the future. In the future, the competitive landscape of the optical transceiver market will continue to change with the development of technology and the expansion of application scope.
