Low power consumptionDirect Attach Cables (DAC) – 10G to 800G
Cost-effective Direct Attach Copper Cables for short-reach data center connections. Passive and active DAC options from 10G SFP+ to 800G OSFP with lengths from 0.5m to 10m.
Direct Attach Copper (DAC) cables deliver high-speed connectivity for data centers and network equipment rooms where cost efficiency and low power consumption are priorities. These pre-terminated copper assemblies eliminate the need for separate transceivers, reducing both equipment costs and power draw compared to optical solutions.
EdgeOptic's DAC portfolio spans 10G to 800G speeds, with passive cables reaching up to 7 meters for lower speeds and 3 meters for higher bandwidths. For connections requiring extended reach without transitioning to fiber, our active DAC options provide signal amplification to maintain data integrity over longer distances.
When connecting equipment operating at different speeds—such as 100G switches to 25G servers or 40G infrastructure to 10G devices—our breakout DAC cables split high-bandwidth connections into multiple lower-speed ports, simplifying network architecture and reducing port costs.
All EdgeOptic DAC cables are coded for compatibility with major networking vendors including Cisco, Juniper, HPE, Dell, and Mellanox. Our engineering team can also provide custom configurations with different vendor coding on each end—ideal for mixed-vendor environments in data center deployments. Contact us for compatibility questions or custom requirements.
