200G DAC direct attach cable VS 200G AOC active optical cable
200G Ethernet has become a hot topic in the market due to its trend of higher transmission rate, higher density, and lower device power consumption. As important components, 200G optical modules , 200G DAC, and 200G AOC have also received attention from everyone. In this blog, ETU-LINK will talk about 200G DAC direct attach cables and 200G AOC active optical cables. 200G DAC The 200G DAC direct attach cable mainly comes in two packages: QSFP56 and QSFP28-DD. The difference between the two is that the QSFP56 DAC package uses four transmit and receive ports, each with a transmission rate of 50G, while the QSFP28-DD DAC package has eight transmit and receive ports, each with a transmission rate of 25G, and is compatible with QSFP forward and backward, and can be compatible with existing QSFP28 optical modules and AOC/DAC high-speed cables. 200G QSFP56 direct attach cables are divided into three types: 200G QSFP56 to QSFP56 DAC, 200G QSFP56 to 2x100G QSFP28 DAC, a...
