In today's society, the capacity and speed requirements for data communication are increasing, and the construction of higher bandwidth and faster data transmission infrastructure is imperative. The 400G OSFP is an 8-channel small pluggable optical module, which greatly improves the capacity and speed of data transmission. From the early 100 Gigabit, Gigabit and 10 Gigabit to the current 400G used in head application scenarios, the speed has been increasing, and this historical evolution process has taken only 10 years. This article will provide an overview of the details of the various 400G OSFP optical module types, and share some frequently asked questions about 400G OSFP optical modules.
OSFP (Octal Small Form Factor Pluggable) optical module, which contains 8 high-speed electrical channels, each running at 50 Gbs of speed, for a total bandwidth of 400 Gbs. 400G OSFP optical modules can be divided into different types based on different parameters. 400G optical modules can be divided into multi-mode optical modules and single-mode optical modulesIn terms of transmission distance, it can be divided into SR8, DR4, FR4, FR8, and LR4;In terms of scheme modulation, it can be divided into NRZ and PAM4. The following table provides an intuitive understanding of the different types of 400G OSFP optical modules.
One of the great advantages of 400G OSFP optical modules is the significant increase in bandwidth. The 400G OSFP optical module greatly improves the network transmission rate and capacity, realizes faster data transmission and reduces data latency. This is critical in real-world client applications. In addition, the compact appearance of the 400G OSFP greatly saves space, and can achieve a denser layout in the use of data center equipment to achieve maximum capacity data transmission and exchange.
Q&A: What Are the Differences Between 400G OSFP Optical Modules and Previous Optical Modules?
The 400G OSFP optical module is not very different from the previous optical module in terms of appearance, but it has a qualitative leap from the low-rate optical module in terms of transmission rate and capacity. The eight-channel rate transmission is integrated in the same volume of the enclosure, but the transmission rate is four times higher than that of the 100G optical module. The widespread application of 400G OSFP optical modules will bring earth-shaking changes to modern networks.
What are the application fields of 400G OSFP optical transceivers?
Strictly speaking, the application field of 400G OSFP optical modules is not popular, and it is mainly used for broadband access of operators, the core link of large data centers, and the core link of the national supercomputing center. In general, the application of 400G OSFP optical modules is concentrated in the core layer of the data center.
What is the compatibility of 400G OSFP optical modules?
The 400G OSFP optical module is compatible with brands such as Huawei, H3C, and Ruijie.
Do 400G OSFP Optical Modules Require Special Maintenance?
No, the 400G OSFP transceiver does not require special maintenance. Regularly check the cleanliness to be sufficient for optimal performance. Following the manufacturer's guidelines and keeping the firmware up to date can help extend the life without the need for specialized maintenance.
