The growth of network bandwidth demand promotes the development of data transmission rate. Now 40G speed obviously can not meet the needs of data transmission, so 100G was born under this background. In the 100G short distance transmission scheme (500m-2km), the 100G QSFP28 PSM4 optical module is a more cost-effective solution for 100G data center. Next, ETU-LINK will introduce what is the 100G QS...

In recent years, with the needs of users and the development of data center, low-speed optical communication products have been unable to meet the needs of daily data transmission. The data transmission speed of optical module has increased from 10G, 25G, 40G to 100G, 200G and even 400G. At present, the package form of 100G optical module have 4 types: CFPP, CFP2, CFP4 and QSFP28 in the market. Th...

As the internal traffic of the Internet giant's data center increases nearly 100% every year, many giants will seek 200G optical module to solve the growing demand for data transmission. There are mainly two types of 200G optical modules: QSFP-DD and QSFP56. Among them, QSFP-DD refers to four channel small pluggable double density package, which is defined by QSFP-DD MSA group, which is twice the ...

Nowadays, with the increasing demand of network throughput and bandwidth, the demand of 100G high-speed optical module is also growing. IEEE has developed two optical module standards for 100G network: 100G SR4 QSFP28 and 100G LR4 QSFP28. But in practical application, because the transmission distance of the above optical modules can not fully cover the transmission distance requirements of t...
