In the rapidly evolving landscape of telecommunications, Direct Attach Copper (DAC) cables have emerged as the backbone of short-range high-speed data transmission. As global data consumption skyrockets driven by 5G, Cloud Computing, and Artificial Intelligence, the demand for cost-effective and low-latency interconnects has never been higher. DAC cables, particularly QSFP28, QSFP56, and the emerging QSFP-DD formats, are the preferred choice for Top-of-Rack (ToR) switching, connecting servers to switches within 7 meters.
Currently, the global market is witnessing a transition from 10G and 40G toward 100G, 400G, and even 800G architectures. Enterprises and hyperscale data centers are prioritizing power efficiency. Unlike Active Optical Cables (AOC), DAC cables consume near-zero power and offer superior thermal management, making them an environmentally sustainable and economically viable solution for high-density environments.
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 termination product manufacturers and solution providers. We are dedicated to developing and manufacturing a wide range of passive and active products for telecommunication networks, enterprise networks, and data centers.
With more than 13 years of experience, we follow strict industry standards, utilizing mature scientific methods to ensure 100% of our products are tested and inspected before shipment. Our mission is to leverage our extensive production capacity to help our customers outperform their competitors.
The explosion of Generative AI requires massive GPU clusters. Our DAC cables provide the ultra-low latency necessary for synchronized processing across thousands of nodes.
Global procurement teams demand flexibility. Our products are fully compatible with Cisco, Huawei, ZTE, Juniper, Arista, and Mellanox, reducing vendor lock-in.
With ESG goals becoming critical, the passive nature of DAC cables helps operators reduce the carbon footprint of their cooling systems and power usage.
In regions like North America and Europe, local application scenarios often involve upgrading legacy data centers to support higher bandwidth for remote work and streaming services. Procurement officers are increasingly looking for reliable China-based manufacturers who can offer short lead times, customized cable lengths, and rigorous signal integrity certifications (SFF-8431, SFF-8665).
