What you get ordering this from us
Ordered by part number
QSFP-100G-LR4-S is what is quoted and QSFP-100G-LR4-S is what ships; where an alternate code is genuinely the same part we name it rather than swap it silently.
Answered by a human
A quote comes back with the reasoning attached, including the cases where we think you should buy something else.
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.
Questions buyers ask about this part
Is QSFP-100G-LR4-S genuine and is the warranty intact?
Yes. It ships new in Cisco packaging, which is what keeps the warranty and the firmware entitlement valid. Anything we cannot supply that way we tell you about before you order.
Will QSFP-100G-LR4-S 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, since both ends and the switch have to agree.
