Product overview
QSFP-100G-CU2M is a Cisco 100GBASE-CR4 passive copper DAC cable, 2m. 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.
Tell us the switch at each end and we will confirm the coding before anything ships, not after it fails to link.

What you get ordering this from us
Ordered by part number
The order is placed against QSFP-100G-CU2M, not against a description of it, so there is no room for a substitution you did not agree to.
Reach checked against the run
Fibre type, connector and distance are checked together, so the optic suits the path and not just the port.
Answered by a human
A quote comes back with the reasoning attached, including the cases where we think you should buy something else.
Questions buyers ask about this part
- Is QSFP-100G-CU2M genuine and is the warranty intact?
- Yes. Supplied new and unopened, so the manufacturer warranty and firmware update path stay supported. No grey-market stock and no refurbished units sold as new.
- Will QSFP-100G-CU2M 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. We quote against a purchase order and hold the price for the quote period, with tiered rates at quantity. Net terms are available once the account is approved.

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.
