BlueOptics Direct Attach Cable 400GBASE QSFP112 0.5 Meter

The BlueOptics Direct Attach Cable (DAC) is a high-performance, passive twinax copper cable designed for 400 Gbps data transmission. With a length of 0.5 meters, it provides a reliable and low-latency connection for data center and high-performance computing environments. This cable features QSFP112 connectors on both ends and complies with IEEE 802.3db and CMIS 5.0 standards, ensuring multi-vendor compatibility.

Advantages

This DAC cable offers exceptional signal integrity and low power consumption (<0.5 W per end), making it an energy-efficient solution for high-speed interconnects. Its passive design requires no external power, reducing complexity and cost. The cable is hot-pluggable and supports 4x 100G PAM4 lane configuration, delivering 400 Gbps aggregate bandwidth.
