HPE 400G QSFP-DD 1.5m Passive Direct Attach Copper Cable

This one is HPE and Aruba AOS-CX coded. Optics and DAC carry vendor EEPROM, and a switch that does not recognise the coding will usually disable the port rather than negotiate a lower speed. Tell us the switch model and we will supply it coded correctly.

This is the 1.5m variant with QSFP-DD ends at 400Gb/s. Passive copper is limited to in-rack runs; past about 5m at high speeds you want active optical instead. Measure the routed path rather than the straight-line distance, because cable management arms and side channels add more than people expect. We stock the range and can supply a mixed set.

Yes. We supply through authorized distribution only, so the part carries the full HPE manufacturer warranty and its firmware update path stays supported. No grey-market stock, no re-labelled drives, no voided warranties.
