, to meet the needs of data communication, has a strong application value. 1 Ethernet-based laser wireless communication system The combination of Ethernet and laser wireless communication can give full play to the advantages of the two systems and improve the application range and reliability of the system greatly. Fig. 1 is a schematic diagram based on one end of the Ethernet laser wireless communication system, and the other end of the structure and the end of the symmetrical state. From

the line can be connected, but the interference between various lines within the line cannot be effectively eliminated, resulting in an increase in the error rate of signal transmission, this affects the overall network performance. Only by building standards can we ensure the normal operation of the network and facilitate the maintenance work in the future. Connection method between devices 1. When the network card is directly connected to the 10 m or M network card of the network card, the hu

electrical port and network device interface, or both ends of the device interface duplex mode mismatch. 2 Twisted-pair cable and RJ-45 head have problems, to detect 3 Fiber connection problem, jumper is alignment device interface, tail fiber and jumper and coupler type match etc. 5.

, and the other RJ45 crystal head is inserted. That is to say, the two ends have the opposite method, and the connected line will form two overlapping * shapes, otherwise it will not be connected. Then, insert the two ends of the prepared dual-gel cable into the NICS of the two computers.2. nic and optical transceiver module: Install the NIC on the computer and set it up. Connect the

basically eliminated. However, if you want to use it for Cascade, its speed also has some advantages. AUI port (Figure 3): It is a transceiver interface. It is used to connect a signal transceiver that is connected to a crude cable. It is a 10BASE-5 network standard. Like 10BASE-2, it is also in the past. Power Interface (Figure 4. Yes. How does a Hub work without it? Beside the power interface of our hub,

1. Do you see the light on the optical transceiver or optical module and the twisted pair port led? A, such as the transceiver of the optical port (FX) LED is not lit, please determine if the fiber link is cross link? The fiber jumper is connected in a parallel way and the other end is connected in a cross way. b, such as a transceiver of the light port (FX)

the workgroup switch and computer equipment network high-speed connection. In the whole optical network, the backbone of the network generally uses quartz fiber network equipment to ensure the transmission distance. and between the Working Group and the workgroup, between the Working Group and the user, uses the plastic optical fiber equipment, realizes entire local area network uses the light to transmit the information. 1. Plastic Fiber Optic Department switch This switch is a departmental

hole center metal makes 8 small holes into a decoration.It is not appropriate for the C26, c27, and c28 capacitors to share one pass hole. at most two devices share one pass hole., Beyond this limit, the capacitor will be ineffective. ============* Network electrical port *============An error occurred while handling the 10 m network electrical port. Because the cat5e twisted pair wires on site may be more than 100 meters long, which is a very large interference source,The

transmission rate (Mbps) of the cable. The Mbps is measured by the number of binary bits transmitted by the line per unit of time,MHz is the number of electrical signals on the line per unit time.Twisted Pair wires can be used in CMSA/CD-based (Carrier Sense Multiple Access/Collission Detection,Carrier-induced Multi-Channel Access/conflict detection) technology, that is, 10 BASE-T (10 Mbps) and 100 BASE-T (Mbps) Ethernet (Ethernet), specific provisions include:● The maximum length of a twisted

resistance is connected to the far end of the transmission cable.(3) RS-485 electrical RegulationsBecause the RS-485 is developed from the basis of the RS-422, so many RS-485 electrical regulations and RS-422 is similar. For example, the balanced transmission mode is adopted, and the final resistance must be connected to the transmission line. RS-485 can adopt two-line and four-line mode, two-line can realize real multi-point bidirectional communication. RS-485 bus, widely used RS-485 serial bu

to the farthest end of the transmission cable. (3) RS-485 electrical regulations Because the RS-485 is developed from the RS-422 Foundation, so RS-485 many electrical regulations and RS-422 similar. If all uses the balanced transmission way, all needs in the transmission line to connect the final connection resistance and so on. RS-485 can be used two-line and four-wire mode, the second-tier system can achieve real multiple-point two-way communication. RS-485 bus, when the requirement commu

Whether it is a LAN, a metropolitan area network or a wide area network, it is usually made up of networking devices and transmission media, such as NIC, hub, switch, router, cable, RJ45 connector, etc. As the scale of the network continues to expand, the number of devices that make up the network is expanding rapidly, equipment varieties are also constantly refurbished, if the day-to-day maintenance of these equipment, not regularly to their maintena

routers, and computer network cards connected by twisted-pair wires. Solution: For separate buildings using overhead twisted-pair line cascaded, to optical fiber cascade to reduce the impact of lightning. For the use of overhead twisted-pair wire access to terminal equipment, replaced by metal pipe after the laying of the break-in. If there is trouble in burying the home, the twisted pair shall be laid in a metal pipe and connected to a potential connection of each separate building [5]. The m

commonly used: Single-Mode Optical Fiber and multi-mode optical fiber (the so-called "Mode" refers to a ray of light that enters the optical fiber from a certain angle ). Multimode Optical Fiber is generally used for network connection in the same office building or a relatively closer area. The Single-Mode Optical Fiber delivers higher data quality and longer transmission distance. It is usually used to connect office buildings or geographically dispersed networks. If optical fiber cables are

The plastic fibre-optic departmental switch provides multiple Ethernet fibre ports, providing high-bandwidth, high-performance fibre connections between workgroups or workgroups. Plastic fiber Optic network card with Ethernet plastic fiber interface of the computer PCI card, in line with the IEEE Standard, Plug and Play, support Full-duplex mode. The POF-

to international cabinet standards, so that everyone's plane size is basically unified, can be installed together in a large vertical standard cabinet. The advantages of this is very obvious: on the one hand, can make the equipment occupy the smallest space, on the other hand, it is easy to connect with other network equipment and management, at the same time the room will also appear neat, beautiful. We are often exposed to the placement of the computer room has a network cabinet, server cabi

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 transmit the data into the encoding (10M Ethernet using the Manchester special code, 100M ethernet using the diffe
