Black passive copper DAC cable with QSFP56 connectors, 2m length

Mellanox Technologies

Mellanox MCP1650-H002E26 DAC Cable IB HDR 200Gb/s QSFP56 2m

SKU CH-J7FD-7KGD3

Passive copper cable carries InfiniBand HDR traffic at up to 200 Gb/s over 2 metres with QSFP56 connectors

  • Up to 200Gb/s throughput with 4x 50Gb/s PAM4 lanes
  • IBTA InfiniBand HDR compliant for interoperable deployments
  • Hot-pluggable QSFP56 module enables live insertion and removal
  • Passive copper design operates 0-70°C on a single 3.3V supply
  • SFF-8665 compliant with BER better than 1E-15

Direct-attach cable for 200Gb/s InfiniBand HDR

This Mellanox passive copper cable carries up to 200Gb/s over a 2m link. It uses QSFP56 connectors and four lanes of 50Gb/s PAM4 modulation. The assembly is IBTA InfiniBand HDR compliant and meets SFF-8665 mechanical and electrical requirements. A single 3.3V supply powers the module across an operating case temperature of 0-70C.

Suited for rack-to-rack

Data-centre engineers building HDR clusters or high-throughput storage fabrics will use this cable for short-reach connections. It is not intended for runs longer than the supplied length, nor for equipment that only supports lower-speed QSFP interfaces. Buyers who need extended reach or optical media should select a different solution.

The 200Gb/s HDR data rate over QSFP56 decides fit

Verify that both endpoints negotiate 200Gb/s InfiniBand HDR and present QSFP56 cages before ordering. The passive design requires no external power beyond the 3.3V slot supply and delivers a bit error rate better than 1E-15. Hot-pluggable operation allows insertion or removal without system downtime.

Questions about this item

How do I confirm the link is running at 200Gb/s after connecting the cable?

Check the switch or HCA management interface for an active HDR link at 200Gb/s and verify the reported BER is better than 1E-15.

What comes in the box and do I need separate transceivers?

The package contains the 2m passive copper cable with integrated QSFP56 ends; no separate transceivers are required.

Which cable version should I choose for a 2m IB HDR 200Gb/s link?

Select the MCP1650-H002E26 model — it is specified for 200Gb/s HDR over 2m with QSFP56 connectors.
