Hello everyone! On the eve of the popularity of Wi-Fi 6 and the explosion of IoT applications, traditional gigabit networking cannot meet enterprises' requirements for high-speed, low-latency, and large-capacity networks. Therefore, after "100M optical fiber" and "Gigabit-to-desktop", campus networks have entered the 10G era. Looking back over the past decade,...
Today I would like to share with you a case about the SmartAX MA5800-X2 spontaneous restart issue. See more information shown below. Product model: SmartAX MA5800-X2. ISSUE DESCRIPTION MA5800-X2 restarts suddenly within 14 days to 6 weeks. The configuration commands and version (MA5800V100R020 and SPH320) of the MA5800-X2 are the same as those of the other 50 MA5800-X2s in the environment. ISSUE ANALYSIS 1. Check the power supply...
I would like to share a post about how to configure password-free login and use the RSA authentication on the MA5801-GP08. The procedure is as follows: 1. Configure the Linux client Run the following commands to generate public keys: linux# ssh-keygen -t rsa -b 2048 // Generate a 2048-bit RSA public key password. The content...
Hello, everyone! Today, I want to explain the difference between EDFA and Raman optical amplifiers. Long optical links require amplification of the signal. There are two types of amplifiers - EDFA and Raman. The question is what are the differences between these two amplifiers? And which amplifier should be applied? It...
Hello, everyone! This post is dedicated to the Erbium-doped fiber amplifier(EDFA). I hope you're interested. Working Principles of EDFAs Erbium-doped fibers are the key components of EDFAs and contain Er3+ ions of a certain concentration. Before illustrating the working principle of EDFAs, this course introduces the energy level diagram of erbium ions....
