3m 40G QSFP+ to 4x10G SFP+ Breakout DAC: High-Stability 40G Migration
Op2Link high-speed cable (DAC) is exterminated with a QSFP+ connector on one end, and four 10G SFP+ connectors on the other end to connect 40G devices and 10G devices, suitable for 10G and 40G network connections. By using passive copper technology to provide reliable transport connections without the need for an additional power supply. The DAC cables provide a cost-effective solution for interconnecting equipment in telecommunication carrier’s server room or data center for short distance transmission.
Technical Performance & Material Advantage
At 3 meters, the choice of wire gauge (AWG) is critical to combat signal attenuation.

Superior Energy Saving: Low Consumption of Direct Attach Copper Cable
The 40G QSFP to 4*10G SFP+ 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 copper cable offer a sustainable solution. Additionally, their reliability and seamless integration capabilities ensure that can enhance network infrastructure without sacrificing efficiency. By choosing branch Direct Attach Copper Cable with low power consumption, can create a more energy-efficient and sustainable networking environment while achieving cost savings.
Cost-Effective Networking Solution
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, 40G 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.
Expert Insight: The Op2Link Advantage
Many clients worry that AWG24 is too stiff for tight rack spaces. While it is more robust, the trade-off is unbeatable link stability. If you are running mission-critical 10G storage traffic over a 3-meter jump, the extra copper in our AWG24 cable acts as an insurance policy against EMI and signal drops common in thinner, cheaper alternatives.
Solving Your Migration Complexity
Moving from 10G to 40G doesn’t have to be a compatibility nightmare. Whether you are struggling with multi-vendor handshaking (e.g., Cisco switch to Dell servers) or trying to calculate the thermal impact of different cable gauges in your rack, UnitekFiber is here to guide you. We can provide custom coding for each end of the breakout cable and help you select the ideal AWG for your specific airflow requirements.
