SKU CH-DH19-Q95W0 MPN MCP1650-H002E26-AX

A 2-metre passive DAC cable carrying 200 Gb InfiniBand HDR over QSFP56 for direct switch-to-switch links

  • 200 Gb/s throughput for HDR InfiniBand clusters
  • 2 metre passive DAC keeps latency low
  • QSFP56 connectors match Mellanox-compatible ports
  • MSA-compliant twinax works in multi-vendor racks
  • Pre-programmed EEPROM avoids link negotiation errors

200G QSFP56 HDR passive DAC

The Axiom MCP1650-H002E26-AX is a 200G QSFP56 InfiniBand HDR passive direct attach cable built for high-density interconnects in data-centre racks. It targets network engineers and system integrators who need a validated twinax link between HDR-capable switches, routers or adapters without the cost and power draw of active optics.

MSA-compliant twinax construction

The cable is fully compliant with the multi-sourcing agreement, so it fits and functions in any MSA-compliant QSFP56 port. Pre-configured application-specific code and unique serialisation eliminate communication conflicts and simplify inventory tracking, while the passive design means no external power is required for the two-metre reach.

Mellanox-coded compatibility

The single specification that decides fit is the factory-programmed Mellanox-compatible identity burned into the module EEPROM; without that code the link will not come up on Mellanox HDR equipment. Buyers whose switches enforce a different vendor lock-in will find this cable incompatible.

Questions about this item

What data rate does the QSFP56 interface support on this 200G InfiniBand HDR cable?

The QSFP56 interface on this cable supports a 200G data rate for InfiniBand HDR connections.

What physical connector and length does this cable use for rack installation?

This cable uses QSFP56 connectors on both ends and is 2 metres long for rack-to-rack or intra-rack connections.

How is this passive DAC installed and what common step is missed?

Insert each QSFP56 end firmly until the latch clicks; the step often missed is verifying the link LED comes up on both ports.
