A summary of solutions for Gigabit Optical Fiber switches to solve Internet cafe Problems

In the course of the development of the Internet cafe industry, there are always many problems that need to be solved. The following is a collection of solutions to these problems, it can give us some inspiration in terms of Gigabit Optical Fiber switches.

Since the development of the Internet cafe industry, it has gone through countless leaps and bounds, both in the initial kitten age and in the current Gigabit fiber switch optical fiber access, each successful "transformation" has no influence on the driving force caused by the emergence of new technologies and solutions.

The emergence of fiber optic solutions for gigabit fiber switches in Internet cafes will undoubtedly bring a spring breeze to the entire Internet cafe industry. Compared with the current network exchange solution that uses twisted pair wires as the backbone transmission medium, the optical fiber solution will undoubtedly leave it behind.

I believe that with the help of the fiber optic solution for gigabit fiber switches in Internet cafes, the entire Internet cafe industry can grow more stable, efficient, and fast! Optical fiber is generally made from SiO2 Z SiO2) by special pulling process. It no longer uses electronic signals to transmit data, but uses optical pulse to transmit signals. It is such a special material that gives it incomparable advantages over cables:

High bandwidth and high transmission capacity. In the optical fiber transmission system, because the carrier is light and the optical frequency is relatively high, the bandwidth is high and the transmission capacity is large. Strong anti-electromagnetic interference. Because the optical fiber transmits a beam, it is highly resistant to electromagnetic interference. Even if exposed to V or even v strong electromagnetic interference, it will not be affected.

Low signal loss. The signal loss of a gigabit optical fiber switch is 0.2dB/km, which is close to the theoretical limit of optical fiber transmission. The transmission distance is long. Optical Fiber Transmission Distance can easily reach more than 550 meters, and copper cables have distance requirements. We all know that cables fully comply with cat5 or cat6 standards, with 150 M theoretical transmission of 100 M and M theoretical transmission of M.

We only need to solve the transmission medium from servers to Gigabit Optical Fiber switches, as well as from the primary Gigabit Optical Fiber switch to the access Gigabit Optical Fiber switch. The network speed and smoothness can be improved to some extent! Many people are still discussing how to set the cache, how to configure the server, the best brand of software XX, but ignore the most important thing that affects performance, that is, your Lan!

Internet cafes, especially diskless Internet cafes, and the fiber-optic scheme of Gigabit Optical Fiber switches in Lan are necessary. The following reasons are the most convincing reasons! With the increase in disk performance, the bottleneck of the current server performance does not come from the disk array. Needless to say, SAS, ES, SSD will also become mainstream in the future, and the memory price is cabbage price. The CPU gradually changes from 4-core to 8-core. What do you think is the server bottleneck?

With the improvement of diskless or diskless technology, software systems gradually rely on caching instead of array performance. The bottleneck is not the configuration of other parts of the server, but the local network. Not only the internet, but with the increase in client configuration, the customer's wide application, as well as a large number of local data reads and writes, P2P, and even Intranet DoS. Is it still unable to explain the bottleneck affecting the performance of Internet cafes?
