I often see an introduction to the use of fiber-optic fast Internet access on the signboard at the entrance of an Internet cafe. As an internet cafe operator, do you understand the essence of fiber-
access and ADSL access? The following describes the advantages and disadvantages of fiber-optic network access and ADSL Network access in terms of Internet cafe network performance requirements, access costs, fee levels, and application environment. According to the network performance requirements of
place to set a fixed IP,IP address is 192.168.1.XX (room number), the mask is 255.255.255, the default gateway fills the light Cat IP, here is the 192.168.1.1,dns server is also filled with light cat ip:192.168.1.1, set up a fixed IP, and distinguish the router's DHCP range, so there will be no IP conflict.4, there is a easiest way, directly through the 192.168.1.1 into the Light Cat set page account number: telecomadmin, Password: ne7ja%5m, go directly to the IP of the network segment, changed
Internet cafe, there should be two status indicators that are fast and continue to flash, one is to connect the test computer's Port 1, the other port is connected to the computer that is responsible for data replication, put "number tube" on it, write down the port status, and complete the matching task for a group of Network cables. Open "Network Neighbor" on the test computer, find the shared folder of the other computer, copy the big data file, a
Reflector and is abbreviated to OTDR (optical time domain reflectometer). A representative measurement curve is shown in Figure 4. A and D two strong echoes on the curve correspond to the reflection caused by the input and output faces of the fiber. The curve b point corresponds to a scattering echo caused by a fiber optic connector. The C point may correspond
is expected to develop the Optical Fiber Ethernet virtual private network function. The proposal on this standard has been re-discussed to increase the number of VLAN sectors. As a result, the number of VPNs will increase from several thousand to several 100,000. Fiber-optic Ethernet VPN may be classified into MAN fields in a wide range.Currently and in the plan
integrated access standard based on ITU-TG.984.x standards, the available bandwidth is about 1111 Mbit/s, although the technical implementation is complex, however, it has the advantages of high bandwidth, high efficiency, wide coverage, and rich user interfaces. It is regarded by some European and American operators as an ideal technology for broadband access network services. The EPON solution has good scalability and can implement multiple

The transmission device side optical interface is generally used SC connector.SC Interface Physical DiagramLC interface Type:LC connectors are similar in shape to SC connectors and smaller than SC connectors.LC Interface Physical DiagramST connector:St connectors are also called snap-in round joints, fo
With the decrease of the cost of Ethernet equipment and the increasing demand for network applications, the application of Gigabit Ethernet has become a trend. Tyco Electronics has a complete solution for the amp XG Cabling System, which is used in 10G Ethernet. The integrated solution already includes single-mode fiber, multimode optical fiber transmission 300 m (XG f
The Application of Fiber-Optic Ethernet switches is becoming more and more extensive. Here we mainly introduce the ACCESS scheme of fiber-optic Ethernet switches and its practical application problems. The fiber-optic Ethernet tec
: Single mode: l Wavelength 1310 single-mode long distance lh wavelength 1310,1550 multimode: SM Wavelength 850 SX/LH indicates the use of Single-mode or multimode fiber In the label of the tail fiber connector Note, we often see "fc/pc", "SC/PC" and so on, the meaning of the following 1 "/" The previous section of the connector model for the tail fiber
In the past two years, with the development of the communication industry and the implementation of national policies, China's FTTH has developed rapidly from the pilot project to the current scale deployment. As an important part of FTTH construction, fiber connection doubles the engineering volume. Meanwhile, the extension of FTTH construction connection point to the indoor environment also brings about a significant increase in the difficulty of wo
Now, the position of Optical Fiber Ethernet switches in the switching industry is becoming more and more important. Here we mainly introduce the comprehensive performance of Optical Fiber Ethernet switches. Because Fiber Optic Ethernet switches can provide high-speed and low-cost f
If your home is dial-up Internet users, even if the new fiber-optic households, you must remember to dial the Internet account and password Oh. Fiber-optic Connection router specific steps: First, the household
network interface UNI. In recent years, the new technological revolution represented by the Internet is profoundly changing the traditional telecom concept and architecture. With the gradual opening of access network markets in various countries, the telecom control policy has relaxed, with the increasing competition and the rapid emergence of new business demands, wired technology, including optical fiber
The development of optical fiber access networks is very rapid and has been widely used in various fields. The advantages and disadvantages of optical fiber access networks and ADSL access are analyzed in detail below. The rapid development of the Internet has led to the further prosperity of the
situation of Internet cafes users, the main link is worth the Internet Café users reference, we recommend the first way. The first is the use of optical fiber transceiver to achieve the connection between the fiber and the dual-Wan port router, this way the biggest feature is the low input cost, but also the most sui
