In the rapidly evolving landscape of high-speed data transmission, Direct Attach Copper (DAC) SFP+ cables have emerged as the industry standard for short-range interconnects. As global data traffic surges due to AI, 5G, and Cloud computing, the demand for cost-effective and energy-efficient cabling solutions has skyrocketed.
Currently, 10G SFP+ DAC cables dominate the Top-of-Rack (ToR) switching architectures in data centers worldwide. Unlike Active Optical Cables (AOC), DAC cables utilize passive copper twinax, significantly reducing power consumption and latency. For global enterprises looking to optimize their Total Cost of Ownership (TCO), China-manufactured DAC cables provide the perfect balance of performance and price.

The industry is shifting from 10G and 25G toward 100G and 400G DAC solutions. Procurement managers are increasingly seeking backwards-compatible cables that support multi-generational hardware.
In industrial automation and financial trading systems, cable reliability is non-negotiable. Passive DAC cables, with no active components, offer an incredibly high MTBF (Mean Time Between Failures).
Global buyers now demand customized lengths (0.5m to 7m) and specific EEPROM coding to ensure 100% compatibility with switches from Cisco, Arista, Juniper, and Huawei.
Established in 2012 in Hong Kong as a hi-tech communication enterprise, Kocent Optec Limited has grown into one of China's leading fiber optic and high-speed copper product manufacturers. With our production facilities in mainland China, we bridge the gap between advanced R&D and large-scale manufacturing.
By leveraging our extensive experience and excellent production capacity gained over the years, we magnify the outcome for our valuable customers. We place heavy emphasis on customer collaboration, defining ourselves as your partner in connection solutions rather than just a vendor.
Connecting servers to Top-of-Rack switches within a single rack, where distance is less than 7 meters, maximizing speed while minimizing costs.
Used in base stations and central offices to handle high-volume data backhaul, supporting 5G network expansion and edge computing nodes.
Interconnecting GPU clusters for AI training where low-latency communication between nodes is critical for processing efficiency.
Large-scale deployment in hyperscale data centers where the "Green Power" benefit of DAC cables leads to massive energy savings annually.
We follow strictly fiber optic and copper industry standards by using mature scientific methods. Our factory tour highlights our commitment to quality across all production lines.
