The traditional computing network of data centers is composed of the access layer, the convergence layer and the core layer. However, with the rapid growth of new applications and the amount of data, the requirements on the network architecture are constantly raised. Therefore, a new network topology architecture -- leaf-spine structure is born in the data center. Now, ETU-LINK will introduce the ...

With the application of cloud computing, VR/AR, AI, 5G and other technologies, the bandwidth capacity of the global Internet has become very large. The flat two-layer leaf-spine (Leaf-Spine) architecture used in ultra-large-scale data centers requires a large number of interconnections, because each Leaf is fully interconnected with the spine to maximize non-blocking network connections between sw...

Usually, the ports of the newly purchased optical modules are clean, and there is no need to clean the ports, but for the optical modules that are idle or have not been inserted into the dust cap in time, when they are used again, in order to prevent the transmission performance from being affected, we still have It is necessary to clean the port of the optical module first. Then the following ETU...
