With 500 computers, the Gigabit Optical Fiber switch solution is required. Internet cafes need to support port mirroring, port aggregation, QOS, and other functions of the Gigabit Optical Fiber switch, to meet different network application requirements. Internet cafes with a large number of computers should also have other solutions. 300-about 500 Internet cafes The network center uses two RHS4624GMS fully Gigabit managed Ge Optical Fiber switches for 10 Gigabit cascade. It can provide 32 Gigabi

managed Internet cafe optical fiber switch. It provides 8 Gigabit SFP Optical Fiber ports, 8 independent 10/100/1000Base-T ports, and 48 Gbps backboard bandwidth, it can fully meet the network performance requirements of the entire Internet cafe. It also supports ARP security, port VLAN, and 802.1 QVLAN, Port Mirroring, port aggregation, QOS, and other functions to meet different network application requirements. 2. Eight

Optical fiber is generally made from Z (SiO2) after special pulling process. It no longer uses electronic signals to transmit data, but uses optical pulse to transmit signals, it features high bandwidth, large transmission capacity, low signal loss, and long transmission distance. Therefore, the emergence of the Internet cafe Optical Fiber solution will undoubtedly bring a spring breeze to the entire Internet cafe. The development of the Internet cafe industry has gone through countless leaps an

In recent years, with the development of the communication industry, the number of Internet access methods has also increased. Here we mainly introduce the most widely used PSTN dialing methods, including the introduction of ADSL. When it comes to access networks, we must first involve a bandwidth problem. With the continuous development and improvement of Internet technology, the bandwidth of access networks is divided into narrowband and broadband. Industry experts generally think that broadba

TV CATV access, and ordinary fixed telephone access, but this actually has a huge technical risk. FTTH technology is a new technology that breaks the bottleneck of the last kilometer of communication. Currently, there are three main FTTH technology standards: Ethernet-based point-to-point Ethernet Fiber P2P) technology, Ethernet-Based Passive Optical Network-EPON) technology and General Frame-Based Passive Optical Network-GPON technology. The three F

In the long run, the use of optical fiber to achieve FTTH Epon/gpon will become the mainstream of the future metropolitan Area Network access technology. But the main trend of metropolitan area Network access is broadband, mobile, optical fiber, IP, so broadband wireless technology, especially 3g/4g high-speed broadband technology will
