Direct Attach Copper (DAC) cable is a high-speed copper cable that directly connects servers and network devices. It uses differential signal transmission technology to provide high-speed, low-loss data transmission. DAC cable is usually used for short-distance device interconnection, such as server clusters, storage area networks (SAN), etc. UnitekFiber provides customized a serial of DAC cables, such as 25G/40G/100G DAC trunk cable, 40G-4*10G, 100G-4*25G breakout DAC cable or etc.
Direct attach copper cable (DAC) is a high-speed cable used to connect devices within a data center. It consists of a twinaxial copper cable with optical modules such as SFP+, SFP28, QSFP+, QSFP56 or QSFP28 on both ends, which can be connected to devices such as switches. DAC cable integrates optical modules and optical cables to avoid the possibility of optical ports being contaminated to improve reliability. High-speed DAC cables are usually used for short-distance data transmission, such as within a server rack or between adjacent racks. UnitekFiber not only provides 40G/100G DAC trunk cable, but also breakout DAC cable which is connect one port to up to 4 other ports, such as 40G-4*10G breakout DAC cable, 100G-4*25G breakout DAC cable.
DAC cables are designed to integrate optical modules and optical cables, which is a durable structure and direct connection design help improve the stability of network connections and minimize the risk of signal loss or interruption. DAC cable could be hot-swappable, which simplifies the network setup process, reduces complexity, and simplifies connection configuration. DAC cable will provide simpler installation, maintenance, and upgrades, thereby improving the overall flexibility of network infrastructure.
With the direct data connection provided by DAC cable, data can be transmitted at extremely high speeds to meet the needs of bandwidth-intensive applications and services. UnitekFiber’s DAC cable offers a high-speed data transmission capabilities, supporting various data rates like 10Gbps, 25Gbps, 40Gbps, and 100Gbps. DAC cables enable low-latency and high-bandwidth connectivity within short distances, depending on the copper cable length specification (usually no more than 10 meters). The short reach limitation makes DAC cables suitable for interconnecting devices within the same rack or adjacent racks in a data center.
