Abstract: As the demand for network data transmission continues to grow, 400G OSFP SR4 optical modules are gradually receiving widespread attention as a high-performance data transmission solution. This article will introduce the overview, characteristics, applications and impact on data centers of 400G OSFP SR4 optical modules.
400G OSFP SR4 optical module is an optical fiber transmission solution for high-speed data transmission. Among them, "OSFP" means "Optical Small Form-factor Pluggable", which refers to an optical module specification designed to provide high-performance, high-reliability optical fiber transmission solutions. This optical module uses 100G-PAM4 modulation technology, SR4 is "Short Reach 4", and is mainly used for short-distance data transmission. Usually, the 400G OSFP SR4 optical module is equipped with 4 channels, each channel has a transmission rate of 100Gbps, and the total transmission rate reaches 400Gbps. The 400G OSFP SR4 optical module is similar to other OSFP modules in that it has a compact design and is suitable for high-density network equipment applications. The 400G OSFP SR4 optical module uses MPO/MTP optical fiber transmission media.
Modulation technology: 400G OSFP SR4 optical module uses advanced PAM4 (Pulse Amplitude Modulation 4-Level) modulation technology. Its advantage is that it can achieve twice the bit rate at the same baud rate, which means it can be achieved on a single optical fiber. Higher data transmission rate and reduced transmission power consumption of optical signals.
Optical fiber jumper: The optical fiber jumper matched with the 400G OSFP SR4 optical module usually uses MPO/MTP connectors with a channel number of 8, that is, 4 transmitters and 4 receivers. This connector can support multi-channel data transmission and provide high-bandwidth and high-reliability connections.
Highly integrated design: The 400G OSFPSR4 optical module adopts a highly integrated design, integrating optical transmitter, receiver, modulator, demodulator and other functional modules. Achieving higher performance and smaller size while reducing power consumption.
In data center application scenarios, 400G OSFP SR4 optical modules play an important role. It can be used for high-speed interconnection between data centers, connecting servers, storage devices and network devices to achieve rapid data transmission and processing. By using 400G OSFP SR4 optical modules, data centers can achieve high-density, high-bandwidth data transmission, improve data processing efficiency, and meet the growing demand for data transmission.
In addition, 400G OSFP SR4 optical modules can also be used for server interconnection within data centers. Connect different computing nodes and storage nodes, support large-scale parallel computing and distributed storage applications, improve the efficiency of data processing and analysis, and promote the development and upgrade of data centers.
As a high-performance, high-reliability optical fiber transmission solution, the 400G OSFP SR4 optical module features advanced modulation technology, strong fiber patch cord matching, and highly integrated design. In data center applications, it plays an important role, providing reliable solutions for high-speed data transmission between and within data centers, and promoting the development and upgrade of data centers. With the continuous advancement of technology and the growing market demand, 400G OSFP SR4 optical modules will continue to play an important role and contribute to the development of the network communications field.
