Active cable ACC - enhanced version of DAC high-speed cable

As we all know, DAC active cables are mainly used for interconnection between cabinets. Because the transmission distance of passive copper cable DAC is limited by factors such as high frequency loss of materials and connectors, the maximum length of passive copper cable DAC with transmission rate of 10G/25G can only reach 7m, and the maximum length of passive copper cable DAC with transmission rate of 40G/100G can only reach 5m. If the distance exceeds the above distance, Then AOC active optical cables and optical modules with high cost can only be used.

In order to solve the interconnection cost problem of extending short distance equipment, ACC active copper cable came into being. Now we will introduce what is ACC active copper cable and what are the series types.

ACC active copper cable uses chips to compensate for the high frequency S21 loss of the passive copper cable DAC, so the transmission distance is extended to several meters. Compared with active optical cable AOC and optical module, ACC active copper cable has the advantages of low cost, low power consumption, small temperature change and transparent protocol, which can meet the energy saving and cost control requirements of large data centers.

The transmission rate and package types supported by ACC active copper cables are 10G SFP+, 25G SFP28, 40G QSFP+, 50G QSFP+, 100G QSFP28, and 200G QSFP-DD. Among them, the maximum transmission distance of 10G/25G ACC active copper cables can reach 15m, and the maximum transmission distance of 40G/50G/100/200G ACC active copper cables can reach 7m.

The interconnection products applied to InfiniBand, Ethernet, HPC, cloud computing, Web 2.0, server to shelf, server to storage, or switch to switch will provide customers with the best solution based on their superior performance, flexibility and elasticity.
