transmission definition 300 ~ A video signal of less than 350 lines. The parasitic Impedance Between twisted pair wires is small and the ideal situation tends to be zero), and the high-frequency component loss of the transmitted videos is small. This is especially suitable for transmitting videos with high-definition details over 400 TV lines and transmitting videos with twisted pair wires, some dedicated chips can even be used to transmit video signals modulated into RF. 2) transmission distan

optical fiber network products are mainly used to achieve high-speed network connection between working group switches and computer equipment in the LAN. The main plastic optical fiber network equipment is as follows. A Plastic Optical Fiber Department switch can provide multiple Ethernet Optical Fiber ports to provide high-bandwidth and high-performance Optical Fiber connections between Working Groups or working groups. The plastic optical fiber Nic has a computer pci nic with an Ethernet Plas

used on the telephone); RJ45 head according to the order of the line is divided into two kinds, one is white orange, orange, white green, blue, white blue, green, white Brown, Brown, and the other is white green, green, white orange, blue, white blue, orange, white brown, brown So there are two kinds of lines that use RJ45 connectors: (12345678 corresponds to 12345678), crossover line (12345678 corresponds

-mentioned wired bridges, wireless bridges are easier to deploy than other wired network devices. Many friends who have used Wireless AP and wireless router may say that many Wireless AP and wireless router also have the bridge function. What is the difference between them and Wireless Bridge? Indeed, in principle, the Bridge functions of the above two devices are the same as those of the Wireless Bridge. If they are different, they are generally the same when talking about the wireless bridge s

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 Pair) as the transmission medium to network. T

ObjectiveIn the past few weeks, I have investigated and researched the security of GSM in many aspects, such as the loopholes in GSM communication protocol. In addition, I have a security audit of the most widely used BTS software in the world today. In this article, I'll show you a few of the vulnerabilities I've found in this open source product that will allow an attacker to invade the base station transceiver (BTS) and remotely control its

Detailed explanation of cable connector A lan is to connect individual computers or terminals using networks to exchange information and share resources according to certain protocols. Commonly used network cables include twisted pair wires, coaxial cables, and optical fiber cables. Twisted Pair wires can be divided into shielded twisted pair wires (STP) and unshielded twisted pair wires (UTP) based on whether they are added with the screen layer of a wire mesh ). Most local networks use unshiel

pair of receivers is 1 000 feet (304.8 m ). Adding a relay transmission twisted pair cable is not as good as a coaxial cable. Adding Multiple Relay amplification between twisted pair transceiver may cause some problems and the effect may not be satisfactory. The main problem may be that the balancing conditions are not satisfying, and the causes of compensation and impedance matching. The coaxial cable does not have these problems. Regardless of the

be used for E1, that is, it cannot be used by time slot. To achieve a one-to-multiple-point interconnection using CE1, the center must be 2 m now, and the speed of each branch is N * 64 K Can port CE1 directly connect to the E1 cable and connect to the E1 port of the Peer router? A: No What is the difference between me1 in Cisco 7000 Series and E1 and CE1 in Cisco 2600/3600? A: me1 on Cisco 7000 can be configured as E1 and CE1, while E1 and CE1 on Cisco 2600/3600 only support their own func

Its basic functions are: from parallel to serial data conversion, package assembly and disassembly, network access control, data cache and network signal .The main working principle of the network card: When sending data, the computer writes the data to be transmitted in parallel to the network card cache , the network card to transmi
