Product overview
Cisco lists QSFP-100G-SR4-S-RF as a 100GBASE-SR4 QSFP28 Transceiver module, remanufactured (MMF, 850nm, 100m, MPO-12). Optics have to match at both ends and are frequently vendor-coded, so a module that is electrically correct can still refuse to link. This is 100GBASE-SR4. Tell us both switch models and we will confirm compatibility before it ships.
We return an itemised quote within 48 business hours, and we say plainly when a part is constrained rather than quoting a date we cannot hold.

What you get ordering this from us
Ordered by part number
Quoted and supplied against QSFP-100G-SR4-S-RF specifically, so what arrives is what your build sheet asks for.
Compatibility checked
We confirm the part is supported on your platform before it ships, rather than leaving the check to you.
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.
Questions buyers ask about this part
- Is QSFP-100G-SR4-S-RF 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-SR4-S-RF 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.
