In recent years, with the rapid development of data centers and the increase in data transmission data by manufacturers and users, DAC cables and AOC optical cables are used more and more as a cost-effective high-speed data communication solution to replace optical modules. . The choice between the two will have different impacts on the architecture of the entire network data center. DACs are now widely used in SATA devices, RADI systems, core routers and 10G or 40G Ethernet data centers. But what is a DAC network cable? What are the advantages of DAC?
The optical modules at both ends of the DAC high-speed cable seem to be no different from ordinary optical modules, but in fact it is not a real optical module, because it has no optical lasers and no electronic components, and can only transmit electrical signals, not optical signals. Because of this, DAC high-speed cables are cheaper than optical modules, and can greatly save cost and power consumption in short-distance applications. It is a low-cost and high-efficiency communication solution. Compared with modules, DAC connectors do not have high-priced lasers and other electronic chips, so they save a lot of cost in short-distance transmission, and replace modules with lower costs, bringing higher benefits to network solutions.
What is the structure of the DAC high-speed cable? DAC high-speed cable is composed of silver-plated conductor and foam insulated core wire, and the high-speed cable is formed by shielding. DAC high-speed cables have excellent attenuation performance, low latency and anti-interference. High frequency broadband transmission can also be achieved. SFP28 dac cable is available now!

DAC high-speed cable is generally translated as direct cable, direct-connect copper cable or high-speed cable. , the module head and the copper cable cannot be separated. High-speed cables are accepted by more and more users with significant advantages such as high cost performance, high performance, high speed, high composite and low loss, and become the first choice for high-speed data communication solutions.
A QSFP compatibility matrix is a valuable tool for network administrators, providing information about compatible QSFP transceiver modules, cables, and related products for use with different networking devices, helping to ensure that users can select appropriate components for their specific networking needs.
The advantages of DAC high-speed cables are mainly the following four points:
As an optical module manufacturer, we would like to share with you the advantages:
1. High performance: DAC high-speed cables are suitable for short-distance wiring in data centers, with a wide range of applications and strong integration solution exchange capabilities.
2. Energy saving and environmental protection: The internal material of the high-speed cable is copper core, the natural heat dissipation effect of the copper cable is good, energy saving and environmental protection.
3. Low power consumption: High-speed cables have low power consumption. Since passive cables do not require power; active cables generally consume around 440mW.
4. Low cost: The price of copper cable is much lower than that of optical fiber, and the use of high-speed cables can greatly reduce the wiring cost of the entire data center.
