Now Gigabit Ethernet has been popularized in a large area, and Gigabit Ethernet switches are also widely used in scenarios such as enterprise networks and optical access networks. Gigabit Ethernet has two types of ports, namely RJ45 and SFP ports. These two ports can support the highest transmission rate of Gigabit, and can also be backward compatible with the transmission rate of 10/100M.   ...

From the perspective of the development trend of data centers, the trend of "cloud" and digitalization of enterprises is irreversible. The demand for data centers in information and communication technology (ICT) industries such as cloud computing, big data, and artificial intelligence is increasing, and the demand for data center bandwidth is increasing. With rapid growth of 25% to 35% per year, ...

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...

As networks grow in size, we are seeing a shift from the traditional three-layer network architecture to a flatter, wider Spine-Leaf architecture. Most modern e-commerce, social media and cloud applications use distributed computing to serve their customers.  Distributed computing means that servers speak to servers and work in parallel to create dynamic web pages and answer customer question...

As one of the cores of medium and long-distance optical communication, the optical module plays a role in photoelectric conversion. It is composed of optical devices, functional circuit boards, and optical interfaces. Today, ETU-LINK will introduce to you the components of the optical module—TOSA and ROSA. 1、TOSA TOSA is the main component of the optical transmitter module, whose main functio...

In the establishment of a 10G network, we will face a choice, that is, whether we choose optical fiber cabling or copper cabling. Optical fiber cabling systems are divided into multi-mode（MM) optical fiber cabling systems and single-mode(SM) optical fiber cabling systems, among which 10G MM optical fiber cabling systems need to use 10G SFP+ MM optical modules, 10G AOC active optical...
