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...

A router is a hardware device that connects two or more networks. It acts as a gateway between networks. It is a dedicated intelligent network device that reads the address in each data packet and then decides how to transmit it. Routers can be divided into backbone routers (core routers), enterprise-level routers, and access-level routers.   Generally, backbone routers have multiple optical ...

Two important development trends of optical modules are to increase the transmission rate and extend the transmission distance. However, as the transmission rate increases, the signal transmission distance will be limited by many factors, such as chromatic dispersion, nonlinear effects, and polarization mode dispersion. These factors will limit the increase in transmission rate and trans...
