With the development of the network, as a kind of medium for transmitting data in the integrated wiring system, optical fiber is more and more used by people because it has the advantages of high transmission rate and far distance. As we all know, optical fibers are non-conductive, can be free of shock current, optical fiber cable also has good protection performance, the metal components in the cable to th
The residential network is growing at a rapid rate, which is largely driven by the need to share printers or connect to the Internet with multiple home PC machines. Residential networks and video applications are also closely related, such as televisions, video recorders, DVDs, security cameras, baby monitors, and home audio and video systems. Families with residential networks can enjoy higher returns and can easily add or modify existing applications. However, it is more challenging to create
What do you mean the network cable was unplugged?
The computer network cable is pulled out, in fact, very good understanding, the meaning is inserted into the computer in the network cable was unplugged, the network cable was pulled out, nature will not be able to access the Internet. As a result of the network
Air Blowing Principle
Gas Blowing cables/tubes are used to push micro-tube bundles or micro-cables to the pipe, while the air compressor sends powerful air streams to the sealing silo of the Gas Blowing Machine, this high-speed flow of air forms a drag force on the surface of the cable and pipe, prompting the cable and pipe to move forward. Therefore, the cable a
Comparison of IP transmission technology in cable TV networks
Abstract: IP transmission technology in cable TV networks includes three forms: IP over ATM, IP over SDH, and IP over WDM, this article introduces and compares the three IP Address Transmission Technologies in detail.
Key words: IP technology, cable TV network, IP over ATM, IP over SDH, IP over WD
In the formation of local area network, in accordance with the general wiring of generic specifications, the construction should be used with "rice standard" network cable or on both sides of the crystal head set dedicated "special-shaped number", and in the cabinet to do with "rice mark" or "Number tube" corresponding to the computer identification record Many units have a small number of original computers, later, gradually added some computers, com
Wireless router Setup is more and more simple, but now is the router installation and network connection is not a lot of netizens. How to connect the router network cable? In fact, it is very simple, today's triple small series for you to share the most common 3 kinds of wireless router cable connection methods.

With the extensive laying and use of optical fiber lines, the reliability and security of optical fiber communication systems have attracted more and more attention. Due to the vast territory of China, the terrain and landform are quite different, which may cause many dangerous factors to optical cable lines, including various natural factors and man-made damage to optical cable lines. From the past Analysi
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
As we all know, the network cable is one of the most basic hardware facilities for us to access the Internet and the most inconspicuous equipment. We are used to purchasing a ready-made network cable. We seldom care about how the network cable is made. We only know that the network cable must be composed of eight cores
A sound video transmission design is a very important part of the CCTV system. If a set of built systems choose cameras, lenses, monitors, and video recorders that can produce or process high-quality images, but there is no good transmission system, eventually, the images seen on the monitor will not be satisfactory. According to the "barrel rule", the final image quality will depend on the worst part of the entire system, which is often the transmission system. System designers and installers m
Now is a network of the world, the network to hundreds of millions of computers, notebooks, tablets, mobile phones together. The network connection way, divides into wired and wireless two kinds. Wired connections are basically connected by a network cable. So it is necessary to know the network cable.
One, the network cable, also known as twisted pa

Currently, the access network technology is widely used, and the access network technology is also very commonly used. So I have studied the problems related to the access network technology construction planning and practical application. I will share with you here, I hope it will be useful to you. With the rapid development of broadband multimedia services and optical fiber communication technology, optical fiber communication technology has been more and more widely used in access network tec
Overview
Verification-check whether the bandwidth of the existing cabling system supports voice, 10/100, VoIP, or Gigabit Ethernet
Fault Diagnosis-shows why the existing cabling system cannot support network bandwidth requirements, for example, there is a crosstalk at 11 meters)
Search-detect the device connected to the other end of the cable and display the device configuration speed/duplex mode/line pair)
Identifies unused switch ports for easy
Make the hub port indicator flashing test 10/100 Ethernet uses time domain reflection technology TDR) to measure the cable length and fault distance. A network testing instrument that combines multiple test functions to test the functions of the UTP or coaxial cable product when a twisted pair or coaxial cable site is added, moved, or changed. Whether you are an
The horizontal cable manager is mainly used for cable connections between adjacent units and devices in the cabinet. It has a combination of 1U and 2U, single-sided and double-sided cables, covered cables, and no-covered cables. Cables can be accessed from left and right, up and down, and some of them can also be used for frontend and backend access. The vertical cable
-tube unit
A micro-tube unit is composed of a silicon core layer added to the inner wall of HDPE material. Generally, the inner wall with a diameter of more than 5mm has a flow channel, the inner wall of the microtube diameter below 5mm does not have a flow channel. At present, the external diameter of the micro-tube generally ranges from 3mm to 16mm. The number of fiber cores that can be accommodated in one microtube ranges from 1 core to 288 cores or even higher. When the optical fiber single
the first time he came, he could use the cable jack, presumably I have a signal here. The last session of the affirmation has been passed, always do not go and later also sealed off. While there are days bedroom no one, I put that laptop cable to my side a try, sure enough there is a signal! Suddenly came to the spirit, feel a hope! Perhaps you will say, it is impossible to connect the network
