The Fibre Channel protocol was formulated by the X3T11 team of ANSI in 1988. It has the characteristics of high bandwidth, multi-media, and long-distance transmission. It can realize the transmission of large data files between storage, server and client nodes. In this article, ETU-LINK will focus on introducing the 16G FC DWDM SFP+ series optical modules for 16G Fibre Channel networks. ...

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 ...

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...
