Questions buyers ask about this part

Will this work in my switch?

This one is coded to order. 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.

Which length do I need?

This is the 2m variant with QSFP-DD to 4x QSFP28 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 — cable management arms and side channels add more than people expect. We stock the range and can supply a mixed set.

Is this Nexus Compute part genuine, and is the warranty intact?

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

Do you offer volume pricing and accept purchase orders?

We accept purchase orders from qualified businesses, government and defence agencies, and educational institutions, with net terms and consolidated invoicing available. Email the quantity you need and we will come back within 48 business hours.
