BlueLAN 400G QSFP-DD Direct Attach Cable, 26 AWG, 2m, NVIDIA Compatible

Data center engineers deploying high-density 400G Ethernet fabrics can use this BlueLAN direct attach cable to connect QSFP-DD ports on switches, routers, and network interface cards. It is built for NVIDIA 980-9I35S-00W01A compatible environments, providing a reliable 400GBASE-CR4 link over a short reach.

Key specifications

• Connector type: QSFP-DD
• Cable type: Direct Attach Cable (DAC)
• Data rate: 400 Gbps (400GBASE-CR4)
• Wire gauge: 26 AWG
• Length: 2 m
• Compatibility: NVIDIA 980-9I35S-00W01A

Why choose it

This DAC offers a cost-effective alternative to optical transceivers for short-reach 400G connections. Its 26 AWG construction balances flexibility and signal integrity, while the QSFP-DD form factor supports high port density. The cable is engineered for compatibility with NVIDIA 980-9I35S-00W01A, simplifying deployment in existing infrastructures.

Ideal use cases

• Top-of-rack to end-of-row switching in data centers
• High-performance computing clusters requiring 400G interconnects
• Server-to-switch connections in dense rack environments

Good to know

Direct attach cables are passive and consume less power than active optical cables, making them an efficient choice for short distances. The 2 m length is suitable for intra-rack or adjacent rack links. Ensure your equipment supports QSFP-DD ports and 400GBASE-CR4 signaling.
