100G QSFP28 to 4x25G SFP28 direct attach copper cables (DAC cable) use passive copper technology to provide reliable transport connections without the need for an additional power supply. Breakout QSFP28 DAC cables provide connectivity between 1*100G QSFP28 port and 4*25G SFP28 ports. The DAC cables provide a cost-effective solution for interconnecting equipment in telecommunication carrier's server room or data center for short distance transmission. DAC cables are easy to install, fast, and cost-effective for short distance transmission.
As the demanding of bandwidth speeds pushed to 400G, DAC cable are ideal for short interconnections. The length of DAC cable depend on the transfer rates, at a maximum reach of 3M at 400Gbps data rates. Applications for a data center include between servers in a rack, between a router in a switch in a rack, or between switches in a cluster.
The 100G QSFP28 - 4*25G SFP28 DAC cable are engineered with a focus on low power consumption, delivering energy-efficient networking solutions without compromising performance. By optimizing efficiency and reducing energy usage, the branch DAC cable offer a sustainable solution. Additionally, their reliability and seamless integration capabilities ensure that can enhance network infrastructure without sacrificing efficiency. By choosing branch DAC cable with low power consumption, can create a more energy-efficient and sustainable networking environment while achieving cost savings.
DAC cable are copper wire so there are no delays in switching copper signals to optical and then back to copper. Direct attach copper cables have the lowest latency of all short-reach cables (<8ft /3m). For services such as financial trading, edge computing, AI, AR/VR gaming, enterprise video conferencing, any reduction in latency is an advantage. DAC cables offer low-latency connectivity, ensuring that data travels quickly and efficiently between interconnected devices.
One of the main functions of DAC cables is to provide cost-effective networking solutions for short distance connections. As an alternative to optical transceivers and fiber optic cabling, 100G transceiver module DAC cable offer comparable performance at a lower cost, making them an economical choice for high-speed data transmission in limited network spaces. By eliminating the need for separate transceivers and fiber optic cabling, direct attach copper cable simplify the network setup process, reducing complexity and simplifying connection configuration. This simplicity means easier installation, maintenance and upgrades, increasing the overall agility of the network infrastructure.
Yes, you can. Unitekfiber offers customized dual compatibility solutions for direct attach cables so that you can choose compatibilities for each end individually.
DAC cables are made from shielded Twinax copper coaxial and are factory equipped with modules on either end connected to fixed ports. The modules cannot be removed from the cable. Therefore, all DAC cables are produced at a fixed length.
UnitekFiber's DAC cables includes passive direct-attach cables with speeds ranging from 10 Gbps to 400 Gbps, typically used for short-distance connections in enterprise and data centers or network equipment.
