Product overview
Cisco lists QSFP-100G-LR-S as a 100GBASE-LR QSFP28 Transceiver Module (SMF, 1310nm, 10km, duplex LC). Reach, fibre type and connector have to agree along the whole path, and a patch panel in the middle counts. Send the run length and the fibre already installed and we will match it.
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-LR-S is what is quoted and QSFP-100G-LR-S is what ships; where an alternate code is genuinely the same part we name it rather than swap it silently.
Coded for both ends
Tell us the switch at each end and we confirm the vendor coding before dispatch rather than after a link fails to come up.
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-100G-LR-S 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-LR-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.
