Product overview
This is the Cisco 40GBASE-CR4 passive copper DAC cable, 1m, order code QSFP-H40G-CU1M. Direct-attach copper is cheaper and lower latency than optics but is limited by length and by what each switch will accept. Tell us the two endpoints and we will say which of the two is right for the run.
The listed price is per unit and current; tell us the quantity and we will confirm what it holds at before you raise the order.

What you get ordering this from us
Ordered by part number
The order is placed against QSFP-H40G-CU1M, not against a description of it, so there is no room for a substitution you did not agree to.
No substitutions without asking
If we cannot supply the exact code we tell you what we can supply and why, rather than shipping an equivalent and letting you find out.
Reach checked against the run
Fibre type, connector and distance are checked together, so the optic suits the path and not just the port.
Questions buyers ask about this part
- Is QSFP-H40G-CU1M genuine and is the warranty intact?
- Yes — new and sealed, with the Cisco warranty and the firmware update path intact. We do not sell refurbished stock as new, and we do not source grey-market units.
- Will QSFP-H40G-CU1M work in my server?
- Tell us the switch at both ends of the link. Optics are frequently vendor-coded, so a module that is electrically correct can still refuse to come up; we confirm the coding for both ends before it ships.
- Do you accept purchase orders and quote at volume?
- Yes. Purchase orders are accepted from qualified organisations, net terms are available on approval, and tiered pricing applies at quantity. Tell us how many you need.

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