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...

Generally, the network card is installed on a computer or server, and communicates with another computer, server or other network equipment through the network. According to different application fields of network cards, we can divide them into computer network cards and server network cards. Generally, a computer can use one network card, but for servers, multiple network cards need to be us...

With the advent of 40G Ethernet, many enterprise users have begun to take full advantage of current 10G network equipment to upgrade to 40G networks. However, when high-speed switches and low-speed switches are interconnected, we will encounter the problem of insufficient SFP+ ports. At this time, we can use Yitian CVR-QSFP-SFP10G converter module to convert QSFP+ ports to SFP+ ports, an...

We all know that a switch is a network device used to forward electrical (optical) signals, while a router is a hardware device that connects two or more networks. It acts as a gateway between networks and reads the data in each packet. The address then determines how to transmit the dedicated intelligent network device. Next, ETU-LINK will give you a detailed introduction to the differences ...
