Previously, we wrote an article about the NVL72 interconnection scheme. Some users in the community requested a further explanation of what these different cables in data centers mean. Let’s review where optical connections and copper connections are used in the GB200 standard. The abandoned NVL72 optical interconnection scheme regarding the GB200 architecture and interconnections has … Read more
Introduction In modern data centers, supercomputing clusters, and cloud computing platforms, there is a need for high-speed, low-latency, and stable interconnections between servers, switches, and storage devices. Among various interconnection solutions, DAC (Direct Attach Copper) and AOC (Active Optical Cable) are the two most widely used cable solutions. Although they may seem similar, they each … Read more
CRT (Baidu Baike): The monitor, scientifically known as the “Cathode Ray Tube,” is a type of display that uses a cathode ray tube. It mainly consists of five parts: Electron Gun, Deflection Coils, Shadow Mask, High Voltage Graphite Electrode, and Phosphor Coating along with a Glass Shell. (1) I held a 15-inch Lenovo CRT color … Read more
This year, the AI computing hardware sector is booming — leading companies like Cambricon and Foxconn Industrial Internet are frequently hitting new highs, with daily transaction volumes in sub-sectors like optical modules and liquid cooling exceeding 10 billion. The underlying “blood vessels” supporting this computing power revolution — high-speed transmission cables such as AOC, DAC, … Read more
High-speed cables (DAC, Direct Attach Cable) include passive copper cables, active copper cables (ACC), and active cables (AEC). They are significantly cheaper than fiber optics, which can greatly reduce the costs of data centers. Compared to DAC, active optical cables (AOC) offer advantages such as being lighter, smaller, having lower error rates, and supporting longer … Read more

Let’s review where optical and copper interconnections are used in GB200. The Abandoned NVL72 Optical Interconnection Scheme There has been much discussion about the architecture … Read more
Today, we are going to discuss this mini PC product that was recommended for purchase by viewers in the comments section a few days ago, from the monitor giant AOC’s “MOSS M7” mini PC. This mini PC has a relatively rounded appearance, decent hardware specifications, ample storage space, and uses pure copper fins for cooling. … Read more
