  • Twin-port design doubles link density per cable
  • Passive copper construction needs no external power
  • Supports up to 800 GB/s InfiniBand NDR throughput
  • 5 m length fits standard rack-to-rack runs

NVIDIA Passive Copper Cable IB Twin Port NDR

This NVIDIA passive copper cable provides a twin-port InfiniBand NDR connection rated up to 800 GB/s. It uses OSFP connectors and measures 1.5 metres in length. The cable suits high-performance computing clusters and storage fabrics that require direct-attached links between switches, servers or accelerators. Buyers needing active optical reach or different connector types should look elsewhere.

Capacity and headroom

The link supports up to 800 GB/s aggregate bandwidth across the twin ports, giving headroom for demanding MPI traffic and large dataset transfers. Passive copper construction keeps latency low but limits the run to the supplied 1.5 metre length; longer rack rows or cross-aisle connections will need active or optical alternatives.

Highlights

  • Twin-port design doubles link density per cable
  • Passive copper construction needs no external power
  • Supports up to 800 GB/s InfiniBand NDR throughput
  • 5 m length fits standard rack-to-rack runs

Questions about this item

Will the 1.5 m OSFP cable reach the ports on my existing InfiniBand switch without strain?

The 1.5 m length gives a short, fixed reach between twin OSFP ports; measure the exact port-to-port distance in your rack to confirm it fits without tension.

How can I verify the link is running at the rated 800 GB/s after I connect the cable?

Check the switch or HCA management interface for a negotiated NDR x2 link and monitor throughput counters during traffic to confirm the 800 GB/s rate is active.
