800G DAC Cable OSFP to OSFP Passive Twinax Cable

SVNK 800G OSFP Direct Attach Copper (DAC) Cable

The SVNK 800G OSFP Passive Direct Attach Copper (DAC) cable is a high-performance, cost-effective interconnect solution designed to support 800 Gigabit Ethernet links in next-generation data center, cloud, HPC, and storage environments. Built in the OSFP form factor, this passive copper assembly enables ultra-high-bandwidth short-reach connectivity between switches, routers, servers, and storage systems.

Compliant with OSFP MSA, IEEE 802.3ck, and CMIS specifications, the SVNK 800G OSFP DAC supports 8×100G PAM4 electrical lanes, delivering an aggregate throughput of up to 800G with ultra-low latency, zero optical conversion, and minimal power consumption.

Designed for very short-reach applications, this passive copper cable provides excellent signal integrity, low insertion loss, and low crosstalk, making it ideal for in-rack and adjacent-rack connections where cost, power efficiency, and port density are critical.
