There are many things worth learning about in the Metro optical fiber cable network. Here we mainly introduce the comprehensive comparison of the optical fiber lines in the Metro optical fiber cable network. How to build a Metro optical fiber network? First, it should be based on the network structure of the man. Second, according to the construction idea of the man, the topology of the network should be fl

Ethernet (EtherNet)Originally created by Xerox, the Ethernet was developed jointly by DEC, Intel and Xerox three companies in 1980 as a standard. Ethernet is the most widely used local area network, including standard Ethernet (10Mbps), Fast Ethernet (100Mbps), Gigabit Ethernet (Mbps), and 10G Ethernet, all conforming to the IEEE802.3 Series standard specification.(1) Standard EthernetThe first Ethernet only has a 10Mbps throughput, and it uses the access control method of the CSMA/CD (carrier-l

The application of optical fiber cables in telecommunications and long-distance communication networks has become very popular and mature. In recent years, with the application of Gigabit Ethernet and the gradual arrival of 10-Gigabit Ethernet, more and more applications of optical cables in LAN have been made. In recent years, local area networks, man networks, campus networks, and campus networks have almost all been laid with optical cables, and the proportion of optical fiber cables is growi

Ethernet is the undisputed overlord of the Internet world. It has been firmly occupying the territory of commercial office environments in recent years. The field of control and automation is also moving towards this open, standards-based technology. Do you think the cables used at the reception desk can also meet the demanding requirements of industrial process control and automation technology environments? In fact, COTS (Popular) 5e unshielded twisted pair (UTP) Ethernet cables are very fragi

For new users, connecting to the new youxun SOHO router is a technical activity. Next I will introduce the connection steps in detail.1. Insert the 12 v ac Power adapter connector of the DI-524M into the Power Jack of the rear panel of the DI-524M, the other end is connected to the Power outlet, after Power will see the front panel of the Power indicator light (Power indicator) on. Wait until the DI-524M is started up before the next operation;2. Connect the network

performance is required. A high-speed optical fiber cable network needs to properly select the appropriate testing instrument. Laser and LED The laser emitting power is very high, and the emitted light is very concentrated, while the light emitted by the LED is usually scattered and the power is low. Compared with LEDs, a laser can send high-speed pulses, which is also the main reason for using a laser in high-speed networks. For Single-Mode Optical

Name No. Product Description Features, installation and maintenance PowerCat6 Class 6 UTP cable CAA-00075 PowerCat6 Category 6 4-wire pair CMRPVC cable, 305 m cable case-gray · Supports ultra-high-speed data networks, such as Gigabit Ethernet 1000Base-T and 1000base-TX) and higher speeds · New twisted pair wires are used to ensure optim

One hundred years ago, you won't hear anyone laying telephone lines at home. Fifty years later, the telephone line was laid out very common, but it was never heard of anyone who installed the TV cable at home. Today, all residential buildings have installed telephone lines and cable TV cables in advance. What will happen in the future? The future trend is structured cabling for home computer networks. In th

1. FTTH development at home and abroad The narrow-sense FTTH cable refers to the further extension of fiber to the user side, ITU believes that FTTH from the fiber-optic end of the photoelectric converter to the user no more than 200 meters, thereby eliminating the need to install an electronic access system in the metal, but not excluding photoelectric converters and desktop terminals using unlimited systems, for commercial systems can also be calle

1, test the speed of network cable The transmission speed of the network cable is the most effective way to discriminate the quality of the network cable. In order to be closer to the actual use of the environment, while reducing the external interference link, the author recommends the use of two-machine direct-linked way. At the same time in order to ensure th

With the increasing number of wireless applications in the world, the irony is that it is increasingly necessary to use wires and cables in high-speed environments. A senior system engineer named Carroll Wontrop from Danaher Motion in wooddell, Illinois, said: "wireless is a competitor, but in a habit, it may be difficult for users to perform conversions ". People are worried that wireless communication will be vulnerable to interference from other wireless communications. Therefore, design engi

The daily use of the computer at the same time some friends may encounter is on the internet or just turned on the computer when prompted network cable was unplugged, such a phenomenon makes people very disgusted, the general phenomenon is not the computer network is not connected to the network is always interrupted, so that users can not carry out normal network applications, then how to solve such a phenomenon? Let's first analyze how we can create

The installation of the LAN starts from the cable, which is the most basic part of the network. According to statistics, about 50% of the network failure and cable-related. It can be seen that the quality of cable itself and the quality of cable installation directly affect the healthy operation of the network. In addi

568A line order from left to right in turn: White green, green, white orange, blue, white blue, orange, white brown, Brown. 568B is: white orange, orange, white green, blue, white blue, green, white brown, Brown. The crossover line means: One end is a 568A standard, the other end is a 568B standard twisted pair. Straight line refers to: Both ends are 568A or 568B standard twisted pair. Use direct connection when the following devices are interconnected: 1. Connect the switch or hub to the r
