Product overview
This is the Cisco 100GBASE-CR4 passive copper DAC cable, 1m, remanufactured, order code QSFP-100G-CU1M. Optics have to match at both ends and are frequently vendor-coded, so a module that is electrically correct can still refuse to link. Tell us both switch models and we will confirm compatibility before it ships.
Quotes are itemised down to the accessories, so nothing that is needed to make the part work is left off and discovered later.

What you get ordering this from us
Ordered by part number
QSFP-100G-CU1M is what is quoted and QSFP-100G-CU1M is what ships; where an alternate code is genuinely the same part we name it rather than swap it silently.
Compatibility checked
We confirm the part is supported on your platform before it ships, rather than leaving the check to you.
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-CU1M 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-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. 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.
