Abstract: The 400G QSFP-DD optical transceiver is an optical communication device with high bandwidth and high density, and is suitable for various data centers and communication networks. This article will introduce the classification and application fields of 400G QSFP-DD optical transceivers.
400G QSFP DD transceiver can be classified according to factors such as their transmission rate, fiber type, and working distance. According to different transmission rates, it can be divided into 400G QSFP-DD SR8 optical transceivers, with a transmission distance of up to 100m. 400G QSFP-DD DR4 optical transceiver, transmission distance up to 500m. 400G QSFP-DD FR4 optical transceiver, transmission distance up to 2km. The SR8 optical transceiver is suitable for short-distance transmission, the DR4 optical transceiver is suitable for medium-distance transmission, and the FR4 optical transceiver is suitable for long-distance transmission. At present, the application of longer-distance 400G optical transceivers is not very popular, but as the demand for high-speed and high-capacity transmission increases, ultra-long-distance 400G optical transceivers will become increasingly mature and widely used.
400G QSFP-DD optical transceivers are widely used in data centers, communication networks, high-performance computing and other fields. Specific applications are as follows:
Data centers require high-speed, high-density communication equipment to support large-scale data transmission and processing. The 400G QSFP-DD optical transceiver has the characteristics of high bandwidth and high density, which can meet the needs of data centers for high-speed transmission and large-capacity storage. It can be used for high-speed interconnection between servers, data transmission between storage devices, and connections between data centers and external networks.
With the commercialization of 5G networks and the development of cloud computing, the requirements for the transmission rate and bandwidth of communication networks are becoming higher and higher. 400G QSFP-DD optical transceivers can provide high-speed, high-bandwidth transmission capabilities to meet the communication network's needs for large-capacity data transmission and high-speed data processing. It can be used for interconnection between optical transport networks, optical switches, optical routers and other equipment.
High-performance computing requires massive data transmission and processing capabilities to support applications such as scientific computing, artificial intelligence, and big data analysis. The 400G QSFP-DD optical transceiver can quickly transmit large amounts of data, provide high-speed, low-latency communication capabilities, and meet the data transmission performance requirements of high-performance computing. It can be used for interconnection between servers, data transmission between storage devices, and connections between computing clusters and data storage.
To sum up, the 400G QSFP-DD optical transceiver is a high-performance, high-bandwidth optical communication equipment suitable for data centers, communication networks, high-performance computing and other fields. Its classification includes classification based on factors such as transmission rate, fiber type, and operating distance. With the advent of the digital era, the demand for large-capacity and high-speed transmission will be increasing, and 400G QSFP-DD optical transceivers will play an important role in the future communications field.
