dedicated line (such as a fluke 620/dspl00) can be checked out. A string-winding fault is not easy to find because it does not perform well when the network is running at low speeds or when traffic is low, and it has a huge impact when the network is busy or running at a high speed. This is because a string wrap can cause very large near-end crosstalk (NEXT). The verification test of cable requires convenient and fast use of test instruments. For exa

The access network system is widely used and has been well developed in various fields. It also plays an important role in cable TV return. After more than 20 years of development, China's cable TV network line is now more than 3 million kilometers in length, the optical fiber trunk line reaches 0.26 million kilometers, and nearly 2000 counties have opened

[Abstract]: This paper introduces the DVB-based Data Broadcast System (IP over DVB) developed by the Blue topology company for cable TV networks, which focuses on the system structure, the front-end system structure and implementation, and the design and implementation of the backend data receiving card. Key parts of t

of optical cables, the number of failures of optical cable lines is increasing. Fault Identification is difficult in the traditional optical cable line maintenance and management mode. Long troubleshooting time affects the normal operation of the communication network, resulting in huge economic losses each year due to communication cable faults. Therefore, the

Recommended cable selection for LAN Monitoring System Integrated Wiring In the LAN, the monitoring system is widely used, including transmission lines, hubs, network management centers, and other devices. The information network is based on the Integrated Wiring System, it directly affects the performance of the secur

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

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 th

win8.1 system notebook connection use HDMI HD cable to connect to TV no sound how to solve? win8.1 system notebook has an HDMI interface, as long as the use of HDMI high-definition cable can be connected to the monitor, LCD TV screen display, so you can operate under the large screens. But some win8.1

wires have weak anti-aging capabilities, and only one image can be transmitted at a time. Therefore, it is suitable for video surveillance of network cameras in medium and short distances, with relatively scattered camera points, or with relatively close but concentrated points, such as banks, hotel chains, supermarkets, or university campuses. Coaxial cable.The coaxial cable is the most traditional video transmission method, and its anti-interferenc

XP system cannot connect to the solution that prompts "network cable to be unplugged" Specifically as follows: 1, again check whether the network cable is not plugged, network cable has no problems. 2, check the Internet equipment, the modem has no power, the modem is not because of the heat failure. 3, chec
