As the digital transformation accelerates globally, the demand for higher bandwidth is reaching unprecedented levels. The transition from 100G to 400G Ethernet has become the cornerstone for hyperscale data centers, AI computing clusters, and cloud service providers. In this landscape, 400G Direct Attach Copper (DAC) cables have emerged as the most cost-effective and energy-efficient solution for short-reach interconnections.
Industrially, 400G DAC technology is vital for Top-of-Rack (ToR) switching, linking servers to switches within a range of 1 to 5 meters. Unlike optical transceivers, DACs consume near-zero power and generate minimal heat, making them an essential component for "Green Data Centers" aiming to reduce their PUE (Power Usage Effectiveness) scores.
While 400G is the current mainstream, the industry is already eyeing 800G. China's manufacturing sector is at the forefront of this evolution, developing OSFP and QSFP-DD form factors that ensure backward compatibility while doubling the throughput. Reliable 400G DAC manufacturers are now focusing on Signal Integrity (SI) and advanced PAM4 modulation techniques.
Kocent Optec Limited, established in 2012 in Hong Kong as a hi-tech communication enterprise, stands as one of China's leading fiber optic termination product manufacturers and solution providers.
With over 13 years of specialized experience, we are dedicated to developing and manufacturing a comprehensive range of fiber optic communication products. From passive components to active modules, our solutions serve telecommunication networks, enterprise infrastructure, and global data centers.
By leveraging our extensive production capacity and technical expertise, we empower our customers to expand their core competencies and outperform competitors. We define ourselves not just as a supplier, but as your strategic partner in fiber optic connectivity.
Global cloud giants require massive volumes of 400G DAC for high-density cabling. Our cables support QSFP-DD to QSFP-DD and breakout configurations (400G to 4x100G), meeting the rigorous demands of low latency and high stability.
Artificial Intelligence training clusters rely on rapid data exchange between GPUs. 400G DAC provides the necessary bandwidth without the latency overhead of optical-to-electrical conversion, perfect for localized AI server racks.
In the world of High-Frequency Trading (HFT), every microsecond counts. The physical copper medium of DACs offers the lowest possible latency, making them the preferred choice for financial data centers.
As 5G drives processing closer to the user, localized edge nodes require robust, easy-to-deploy 400G connections. Our DACs are "plug-and-play," reducing installation complexity and maintenance costs.
We strictly follow fiber optic industry standards, using mature scientific methods to deliver products on time while ensuring 100% testing and inspection before shipment.
