FTTH, the concept that has been hotly debated by people in recent years, drives the demand for fiber optic cables and its related products. However, fiber optic cable is fragile and hard to splice, which is worthy of consideration before installation. To make good use of fiber optic cable, well-organized fiber optic cable installation is a necessity. Fiber Optic Cable Introduction Fiber optic cable is a technology that uses small threads made of glass or plastic (fibers) to transmit data. However cheap and light it is, the material brings a troubling problem in fiber optic cable installation. It is an assembly similar to an electrical cable while the former one carries light and the latter carries electricity. Normally, fiber optic cable comes in two types, namely, single mode fiber (SMF) and multimode fiber (MMF). Single mode fiber is suitable for long distance data transmission while multimode optical fiber is used in short distance transmission such as computer network linkin

Almost every device connected to the Internet needs an IP address. Previously, the countless IP addresses are assigned manually, which costs a lot of time and energy. As DHCP emerges, IT specialists are not required any longer to spend countless hours providing IPs for every device connected to the network device. But what is DHCP? How does it work and how to configure DHCP for multiple VLANs? What Is DHCP? DHCP – Dynamic Host Configuration Protocol is a network management protocol used on TCP/IP network. There may be at least a DHCP server and many DHCP clients. The DHCP server allows the client to request the IP addresses and other network configurations from the Internet service provider. This process eliminates the need for administrators or users to assign IP address to network devices one by one. Using this protocol, the network administrators will just set up the DHCP server with all the additional network information, and it will do its work dynamically. Both network switc

For many household use, it is common to see just a modem and a router. That’s enough for most family network requirements. However, if you have too many computers to manage, an Ethernet switch is definitely what you need. Since network switch is not prevalent in ordinary homes, many people don’t have a clear understanding of it, let alone its usage. Here we will figure out what is an Ethernet switch used for and how to use and Ethernet switch. What Is an Ethernet Switch? An Ethernet switch is a network device used to connect different PCs, servers, laptops or other Ethernet devices to a local area network. In this way, the connected devices can communicate with each other. The switch utilizes an MAC access table to exchange data packets among these devices. Network switches come in many types. Different switches have different applications and functions. They may come in 16, 32 or 64 ports, and also in various port speeds. The basic speed is 10 megabit per second, then 100 megabi
