easy to cause data packet loss during transmission. ● Network cable Interface In the desktop consumption level network interface interfaces are common interfaces BNC interface and RJ-45 interface (similar to the phone interface), there are two interfaces are dual interface. The choice of the interface is related to the network wiring form, in the small shared LAN, BNC port Nic directly connected to other computers and servers through coaxial cable

the Hubei line (Hohhot-Beihai ). The transmission network is dominated by SDH optical transmission, supplemented by Microwave and satellite communication. Currently, the access network is dominated by copper wire access and V5 access, supplemented by wireless access. Microwave Communication and satellite communication are currently in standby status because their capacity is far inferior to that of optical transmission. However, the equipment is very advanced. A 12-meter-diameter automatic trac

similar to a network card, and many people confuse it with a common network card or a common optical network card. Of course, some iSCSIThe primary card can be used as an ordinary network card, but the price is very luxurious. The conventional definition of HbA is to connect the host I/O bus to the computer memory system.. According to this definition, like the video card is connected to the video bus and memory, the network card is connected to the network bus and memory, the SCSI-FC card is c

A disk is composed of circular disks of the same size and coaxial. the disk can be rotated (each disk must be rotated synchronously ). There is a head bracket on one side of the disk, and the head bracket is fixed with a set of heads, each of which is responsible for accessing

category. Some of the more common cable) solutions include micro-coaxial cable, strip cable with controllable impedance, dual-axis cable, and shielded twisted pair cable. Other cable types based on copper wires include parallel cables, four-axis cables, and the RG series microwave cables and Microwave Coaxial Cables ). There are three types of optical fiber cables: Single-mode, multimode, and plastic optic

The Network cables used in computer LAN mainly include twisted pair wires and coaxial cables. Among them, the coaxial cable has been basically eliminated and a large number of twisted pair cables have been used. Twisted Pair wires are divided into two types: Shielded twisted pair wires (STP) and unshielded twisted pair wires (UTP. Because STP is only used in some special cases (such as serious electromagnet

I. LAN interface cable standards 1, 10Base-T: twisted pair cable, generally use RJ-45 connector; maximum effective transmission distance is 100 m from the hub, even the high-quality Category 5 twisted pair can only reach 150 m. The matching resistance is 120 Euro. 2. 10Base5: coarse coaxial cable with plug-in connector and baseband signal. The maximum supported length is 500 m and the maximum segment is 100. The matching resistance is 75 Euro. 3. 10Ba

system. They can be achieved through coaxial cable, optical cable, wireless or microwave. The video transmission system is the system's image signal path. A sound video transmission design is a very important part of the video monitoring system. If a well-built system selects cameras, lenses, monitors, and video recorders that can produce or process high-quality images, but does not have a good transmission system, eventually, the images seen on the

Currently, the mainstream technologies of the broadband access network system include ADSL technology, which can economically transmit several megabits of information per second on the twisted pair copper line. It supports traditional voice services, it also supports data-Oriented Internet access. After the local ADSL Access multiplexing device multiplexing data traffic, it selects a route to the group network to transmit the voice traf

So, does the name of the optical fiber Nic refer to the optical fiber port HbA card? In fact, the optical fiber network card is commonly referred to as the optical fiber channel network card. Due t

The operator connects the fiber-optic cables to the locations where users are concentrated, and then each user is connected to each coaxial splitte

Through these wired or wireless channels, the user'

The characteristic impedance (also called characteristic impedance) of a transmission line is determined by the structure and material of the transmission line, regardless of the length of the transmission line and the amplitude and frequency of the signal.For example, the common CCTV

to be converted from multimode to Single-Mode Optical Fiber for transmission. If a digital signal is used, it can be easily transmitted. In a single input and output mode, the optical distribution amplifier can be used to configure the conversion without any baseband signal attenuation during the transmission process. If you have an existing optical fiber installation that needs to be upgraded, consider replacing all the current transmitters and receiving machines with the new digital multiplex

Testing Instruments and testing standards Before testing, we need to select appropriate testing instruments and testing standards. Generally, we use internationally recognized testers for testing. For example, when testing copper cables, we use a cable test table for basic connectivity (on) testing. When testing Category 5 lines, we used the Mi
