Questions buyers ask about this part
Will this work in my switch?
This one is NVIDIA Spectrum and Quantum 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.
How far will 40G QSFP+ SR4 850nm reach?
Up to 150m over Multimode OM4 MPO. That is the specified maximum on clean fibre with in-spec connectors; a run with several patch panels in it should be planned shorter. The connector is QSFP+. Send us the distance and the fibre type and we will confirm the right optic.
Is this NVIDIA Networking part genuine, and is the warranty intact?
Yes. We supply through authorized distribution only, so the part carries the full NVIDIA Networking 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?
The listed price is per unit and indicative; tiered pricing applies at quantity. 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.

Specifying a system, not just the part?
Optics and cabling are part of the fabric spec on a cluster build, since both ends and the switch have to agree.
