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...

The arrival of the 5G era has brought great opportunities to the optical communication industry, and users have increasingly high requirements for high-speed data transmission. At the same time, it is also driving the upgrade from 100G to 400G. Among 100G optical modules, QSFP28 is the most common type of optical module. So today, let's talk about the difference between the 100G PSM4 and the 100G ...
