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

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

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

Internet access in China has developed very rapidly. It may not matter if many people do not know about cable modem in Internet access. After reading this article, you must have gained a lot, I hope this article will teach you more things. When cable modem uses a cable TV network for high-speed access, the general connection mode is: one end is connected to a com

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

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

1. Overview With the development of information society, network technology has become more and more complex, and as the cornerstone of the network, keel-network cable appears more important. In the current network, there are three kinds of cable media: Optical cable, coaxial cable and digital twisted

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

The local area network is the individual computer or the terminal, uses the communication line to connect each other, follows certain agreement, carries on the information exchange, realizes the resource sharing. Among them, communication lines, that is, transmission medium commonly used: twisted-pair, coaxial cable, optical fiber and so on. From the cost-performance and maintainability, most LANs use unshielded twisted pair (utp-unshielded Twisted Pa

Cables are the main cause of electromagnetic compatibility problems in the system. Therefore, in practice, it is often found that when the external drag cable on the device is removed, the device can pass the test smoothly. When electromagnetic interference occurs on the site, if you unplug the cable, the fault will disappear. This is because the cable is an effi

CATV Broadband Integrated Information network based on 3COM company CATV Access Network platform is a successful implementation of cable TV, data communication and network telephone "three nets in one" on the 750MHz bandwidth fiber-optic coaxial hybrid network (HFC). The open television, telephone, computer line of the public Information network, the main technical indicators to reach the world's advanced level. Now, there are 35 sets of TV programs d

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
