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

advent of optical fiber communication technology, the large potential bandwidth capacity of nearly 30THz has brought the flourishing opportunity to the communication field, especially since the information superhighway was put forward, the optical technology began to permeate the whole communication network, and the optical fiber communication has the trend of advancing to all optical network. Optical fiber communication has gone through more than 20 years in our country. The market is the life

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

In companies, businesses, homes, schools, as long as there are networks where there are network cables, but sometimes to add a network cable from a long way through a layer of barriers to pull the network cable to the destination, It took a lot of money. The company often want to add a machine here, there to add a punching machine. To pull the network line from the ceiling, very dirty, and black, so I had

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

Method/Step: 1 Packing: Super 5 Type network cable marked with cat5e words should be 305 meters (1000 feet) per carton, marked with CAT5 is 5 class line, packaging is not 305.1-meter box may not be network cable. Line above the logo: regular manufacturers of the product logo on the label has length, do the project to facilitate the identification of 1-box line used how many meters, how many rice noodles l

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) You can replace a possible faulty network cable with a normal network cable that you are using. If the network connection to the XP system is normal after the replacement, the original cable is faulty. (2) If there is no replacement of the network cable, first of all, you can carefully check the network

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

Notice on wiring: Features of leather Cable Leather cable is commonly known as Indoor Hanging optical cable, leather cable learning name: Access Network with butterfly introduced optical cable; because of its shape is Butterfly Shape; so some people are called butterfly-sha

Standard Organizations and manufacturers in North America and Europe have long been arguing over the selection and standards of the outer skin of Integrated cabling network data cables, just as they are still using FTP shielding products for UTP. Currently, North America, South America, Asia Pacific, and China all adopt the North America-based cable fire prevention standard UL and NEC (National Electrical Code ), in some parts of Europe, low halogen o
