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 ...

The 10 Gigabit copper module adopts hot pluggable SFP+ package, which can be divided into multi rate and single rate. The multi rate adaptive supports 1G to 10G transmission rate, and the single rate only supports 10G transmission rate. The interface type of 10 Gigabit copper module is RJ45. Its port can support both shielded twisted pair and unshielded twisted pair. It is mainly used in switches,...

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. ...
