A Fibre Channel switch, also called a Fibre Channel switch or SAN switch, is a high-speed network transmission relay device. It uses optical fiber cables as the transmission medium compared with common switches. The advantages of optical fiber transmission are fast speed and strong anti-interference ability. There are two types of Fibre Channel switches: One is the Fibre Channel switch used to connect storage devices. The other is an Ethernet switch. The ports on the switch are optical fiber interfaces. The appearance of the ports is the same as that of ordinary electrical interfaces, but the types of ports are…

One, weak current box put router or switch The optical fiber broadband access to the home is basically uniformly configured with weak current box, for the convenience of unified wiring management and the overall line aesthetics, but the router is not recommended to be placed in the weak current box. When the router is placed in the weak current box, the wireless signal needs to pass through many obstacles, which makes the wireless signal attenuation faster and reduces the coverage of the wireless. The space of weak current box itself is narrow, which is not conducive to the expansion of…

A wired connection between a desktop computer and a wireless router The key to a wireless router is to take advantage of its wireless capabilities, but since desktop computers don't have a wireless network card, we usually use a wired connection to connect the two. A router has five or six LAN interfaces that are key to connecting your computer to your wireless router. We use a cable with a moderate length of 1-2 meters to connect one end of the crystal connector to the computer, and the other end of the crystal connector to a LAN interface of the…

Wireless broadband Wireless broadband includes two kinds, one kind is mobile phone Internet, of course, now can also use the network card through the laptop Internet.
