BlueLAN passive QSFP112 Direct Attach Cable, 400GBASE Ethernet, Infiniband, 1 Meter (BOQ1Q101X1M-BL)

This passive QSFP112 direct attach cable delivers 400 Gbps over copper twinax, making it a straightforward choice for short-reach links in dense data center racks. Unlike active optical cables, it draws no power and adds no latency, which can be an advantage when connecting switches and servers within a row.

Highlights

• QSFP112 to QSFP112 connectors, 1 meter length
• Supports 400GBASE Ethernet and Infiniband
• Passive copper twinax design: zero power consumption
• Hot-pluggable for quick installation

In daily use

The blue jacket helps with port identification in high-density environments. The cable is compliant with IEEE 802.3 and IBTA standards, ensuring interoperability with QSFP112 ports on network switches, servers, and HPC systems.
