Product overview
This is the Arista 100GBASE-SR4 QSFP28 Transceiver Module (MMF, 850nm, 100m, MPO-12), order code QSFP-100G-SR4. 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.
Send the quantity you need and we will come back within 48 business hours with availability confirmed, not estimated.

What you get ordering this from us
Ordered by part number
Quoted and supplied against QSFP-100G-SR4 specifically, so what arrives is what your build sheet asks for.
Reach checked against the run
Fibre type, connector and distance are checked together, so the optic suits the path and not just the port.
Compatibility checked
We confirm the part is supported on your platform before it ships, rather than leaving the check to you.
Questions buyers ask about this part
- Is QSFP-100G-SR4 genuine and is the warranty intact?
- Yes. It ships new in Arista 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 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.
