In recent years, with the rapid development of the Internet, cloud computing and big data, the increasingly high demand for bandwidth has promoted the construction of IT infrastructure data centers. The current speed standard of 10G Ethernet cannot meet the rapid growth of network traffic demands of large and medium-sized enterprises. From the perspective of resource investment and cost, 25G is th...

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 data centers and telecom operators require higher transmission rates for optical modules, what technologies do optical module manufacturers use to achieve higher transmission rates? This article ETU-LINK will reveal the answer for you. 1. Increase the baud rate. The baud rate refers to the modulation rate of the data signal to the carrier. This method is mostly used for low rate optical modules...

With the continuous surge in data center traffic, the market demand for 100G optical modules is also further increasing. Common 100G optical modules include SR4, LR4, ER4, etc. However, in practical applications, due to the length of the optical fiber link. Several types of optical modules alone cannot meet the most cost-effective optical network transmission solutions in data centers. Therefore, ...
