100G DAC Cable QSFP28 to QSFP28 Passive Twinax Cable

SVNK 100G QSFP28 Direct Attach Copper (DAC) Cable

The SVNK 100G QSFP28 Direct Attach Copper (DAC) cable is a high-performance, cost-effective QSFP28-to-QSFP28 copper interconnect solution designed for 100GBASE-CR4 Ethernet and InfiniBand applications. Optimized for very short-reach connectivity, it provides a reliable and power-efficient method to establish 100-gigabit links between 100G QSFP28 ports on switches, servers, and storage systems within racks and across adjacent racks.

SVNK 100G DAC cables are fully compliant with the QSFP28 Multi-Source Agreement (MSA), SFF-8665, IEEE 802.3bj, and InfiniBand HDR specifications, ensuring broad interoperability across leading networking platforms. The cable supports four independent NRZ electrical channels, each operating at data rates of up to 25.78 Gb/s, delivering an aggregate bandwidth of 100 Gb/s.

Built using precision twinax copper cabling and advanced high-frequency design techniques, SVNK DAC assemblies deliver excellent signal integrity with low insertion loss, minimal crosstalk, and ultra-low latency. Their factory-terminated, plug-and-play construction eliminates the need for separate optical modules, reducing both capital and operational costs while simplifying installation and maintenance.

SVNK 100G QSFP28 DAC cables are ideal for high-performance computing (HPC), data centers, and storage networks, where short-distance, high-bandwidth, and low-power connectivity is essential.
