When you access the Internet through broadband, the local connection status shows "The network cable is pulled out". Generally, you need to check and solve the following problems:
1. network cable problems (the network cable is broken, the crystal head is loose, and the network cable quality is poor, such as being bit
signals for transmission in optical fiber. It uses optical fiber transmission devices mainly for video optical terminals and optical fiber transceiver. The video optical transceiver is mainly used for analog camera signal transmission. It has low signal loss, low noise and distortion, and high transmission quality, suitable for long-distance transmission. Fiber optic transceiver is suitable for signal transmission of network cameras. It also has advantages such as long transmission distance, lo
Many Fans surf through self-built proxy servers, hubs, switches, routers, and other devices at home. Many terminals and network devices are required for most home computer networks. In addition, the network structure is simple and computer network wiring may be ignored. PairFor Fans of wireless networks, network cabling is not a concern for the time being. However, the wired network is flexible and secure for economic, compatibility, and transmission speed considerations. Next, let's talk about
When testing the twisted pair cable, the possible problems are: the near-end crosstalk is not passed, the attenuation is not passed, the wiring diagram is not passed, and the length is not passed:1. Causes of inpass of near-end crosstalk may be:1) there is a problem with the endpoint;2) Short Circuit at the remote connection point;3) string pairs;4) External Noise;5) The performance of link cables and connectors is incorrect or is not the same type of

POJ 1966 Cable TV NetworkLinks: http://poj.org/problem?id=1966Test Instructions: in a cable TV network, the repeater connection is bidirectional. If there is at least one route between any two repeaters in the network, the repeater network is called connected, or the repeater network is not connected. An empty network, and a network with only one repeater, are considered to be connected. The safety factor F

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, check whether the network card is disabled:

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
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
