How many meters does the network cable transmit at most? Several common categories of network cable and network cable transmission Maximum network

Today encountered a dual network card work, a computer boss plug two card, a used to connect the outside network, a b connected to a lot of sub-computers, computer boss with a server like.problem : that is, connected to the network network card a display no problem, the computer boss display is connected and can surf t

main driving force of Wan Xiaotong Cable Ethernet is to reduce the cost of Ethernet network, for a wide range of implementation of Gigabit Ethernet, the use of optical fiber transmission solution has been proved to be too expensive, so based on the copper

Have you ever had a working environment that is against your experience? But if you're in the same boat as a cable, you might be able to cause data transfer errors or network delays, or you might be able to damage the entire cable if you drive on the cable. For this, ordinary commercial cables are not even immune to th

Fluke Networks (Fluke Network) has launched an ethernet cable tester "DTX-1800", in addition to the widely used "5e" line, it can also be used to detect "6" and "7" lines with better transmission characteristics. You can check whether the cables used as the measurement object meet the corresponding specifications. The testing frequency is up to 900 MHz. Reduce th

At present, lan construction has been very common, and the integration of Ethernet cards on computers is already a standard configuration. The traces of LAN are everywhere around us. A simple small LAN composed of several computers in the family, large Internet cafes in public entertainment venues, campus networks on campus, office networks in the company, and so on are all examples of local area networks. Although they have various networking modes,

of 1550nm wavelength is more susceptible to bending. Table 1 Test 11.5 and 18mm cylinders are severe. They do not simulate the actual application, but describe the relationship between wavelength and loss, which may not be caused during installation. All the above instructions prove that it is important to follow the correct testing method for single-mode optical fiber cables. All in all, it is fundamental to test the network based on a single-mode
