In the current digital era, the demand for high-speed data transmission has reached unprecedented levels. The OEM 100G QSFP28 DAC (Direct Attach Copper) has emerged as the cornerstone of short-range connectivity within modern data centers. As enterprises transition from 10G and 40G to 100G architectures, DAC cables provide a cost-effective, low-latency, and energy-efficient solution for Top-of-Rack (ToR) switching and server-to-switch interconnects.
Unlike active optical cables (AOC) or optical transceivers, DAC cables utilize passive copper wire, eliminating the need for expensive lasers and power-consuming electronic components. This makes them the primary choice for connections within 5 meters.
Passive 100G QSFP28 DAC cables require zero power to operate, significantly reducing the Thermal Design Power (TDP) of data center racks. This aligns with global "Green Data Center" initiatives.
By avoiding O-E-O (Optical-Electrical-Optical) conversion, DAC cables offer the lowest possible latency, critical for high-frequency trading (HFT) and AI training clusters.
While the industry is buzzing about 400G and 800G, the 100G QSFP28 ecosystem remains the "sweet spot" for global enterprise deployments. The reliability of the QSFP28 form factor ensures its dominance in the medium term. Current trends show a massive surge in 100G DAC procurement for Edge Computing nodes and 5G Distributed Units (DU).
Global procurement teams are increasingly shifting toward OEM solutions to bypass the high margins of brand-name vendors (like Cisco, Arista, or Juniper) without sacrificing compatibility. Kocent Optec Limited bridges this gap by providing high-quality, fully compatible 100G DAC products that meet IEEE 802.3bj standards.
Established in 2012 in Hong Kong as a hi-tech communication enterprise, Kocent Optec Limited is one of China's leading fiber optic termination product manufacturers and solution providers.
