Internet Bar Fiber Access scheme

With the development of Internet cafes in recent years, the demand for network bandwidth has become more and more large. Traditional twisted-pair access because of the slow rate of data transmission, resulting in low network performance in Internet cafes, severely restricts the expansion of the size of Internet cafes, the adoption of new access methods has become irresistible.

Optical fiber is more than traditional twisted pair to provide more network transmission rate, single mode fiber can provide 1000MBIT/S data transmission rate, so the fiber becomes the new access mode of large and medium-sized Internet cafes is the trend. Of course, fiber is not only able to provide higher data transmission rate and greater bandwidth. It also has the data transmission distance is long, the anti-interference ability is strong, the high reliability characteristic.

Today, the domestic Internet cafes have tended to saturation, especially in some large and medium-sized cities in the Internet cafes, a large number. In such a large group of Internet cafes, to maintain their profitability, a good quality of service, fast and stable network platform is essential. Although many internet cafes have adopted optical fiber access, but some large and medium-sized Internet cafes still feel the network bandwidth is not enough, how to increase the network bandwidth at low cost? Dual fiber access is one of the best ways.

Introduction to Dual Fiber access

The dual fiber access scheme is a solution to increase the fiber access and enhance the network performance in the case of single fiber access, which can not satisfy the Internet café users. The core of dual-fiber access is how the two-way fiber is connected to the router. From dual fiber access to the router we can see that the router must have two WAN ports or have more WAN ports, from the cost, dual WAN port routers more suitable for Internet users. While the two WAN ports provided by the dual-WAN router are generally not connected directly to the fiber, dual-fiber access must, from the hardware, take into account how the two-channel fiber and the two WAN ports on the router are connected. (Computer science)

From the current 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 suitable for Internet users a way. In the choice of fiber transceiver, the performance is of course important, but more attention is to access the type of fiber media, if it is single-mode fiber, it is necessary to use Single-mode fiber transceiver, if multimode fiber, you need to use multimode fiber transceiver.

The second is the direct use of a dual-Wan port router provided by the fiber module, but this fiber module needs to be purchased separately, the cost is higher than the fiber-optic transceiver, if the cost considerations, we do not recommend this way to Internet users.

Dual fiber access router scheme for Internet cafes

We mentioned the two ways of Internet café dual fiber access, in this package, we chose the first way. The following figure is a dual fiber access router implemented using a fiber optic transceiver.

　　

The image above is a dual fiber access router network topology map with optical fiber transceiver, when the fiber is connected to the Internet Café Network, first connect to the fiber-optic interface provided by the optical transceiver, and then connect the twisted-pair cable with another RJ-45 interface provided by the fiber transceiver. The optical signals provided by the optical fiber are then converted to electrical signals into the twisted pair, while the other end of the twisted pair is connected to a WAN in the dual-WAN port router to enable data transmission. The same is true for another line. When the dual-fiber and dual-WAN port router is successfully connected, the dual fiber access router is basically successful, and the other devices in the Internet bar also need to be installed.

This is just a matter of hardware considerations, and any one network needs to consider software configuration issues. Since this article is from the hardware point of view, we are not here to introduce the software configuration, you can refer to the configuration of the router can achieve dual-fiber access.

Advantages of Dual Fiber access

It is no doubt that dual fiber access can provide greater bandwidth and improve the performance of Internet cafes.

Dual-fiber Access can also enhance the total bandwidth of the network exports, enhance the Internet Bar network users to access the speed of the network, which is particularly important for users of Internet cafes.

In the case of dual fiber access, the diversification of the fiber line selection ensures the stability of the network and makes the network multi-functional. In the connection to the LAN line, we can choose different lines, such as telecommunications, netcom and so on. When a line fails, another line can replace the faulty line, to ensure the stable operation of the network. and telecom and Netcom and other ISP vendors have different services, so in the dual-fiber access, but also can make the function of the LAN become richer.

I believe we all know that most of the network is now based on the network platform of Telecommunications and Netcom. If we use the telecom and netcom two fiber lines to achieve dual-fiber access, then will enhance the Internet Café computer access to telecommunications and Netcom's network, reduce access to telecommunications and Netcom's network speed difference.
