Product overview
Cisco lists MA-QSFP-40G-SR4 as a Meraki 40GBASE-SR4 QSFP+ Transceiver Module (MMF, MPO-12). Direct-attach copper is cheaper and lower latency than optics but is limited by length and by what each switch will accept. Tell us the two endpoints and we will say which of the two is right for the run.
Tell us the deadline you are working to and we will say whether it is achievable before you commit to it internally.

What you get ordering this from us
Ordered by part number
The order is placed against MA-QSFP-40G-SR4, not against a description of it, so there is no room for a substitution you did not agree to.
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 MA-QSFP-40G-SR4 genuine and is the warranty intact?
Yes, new and sealed, with the Cisco warranty and the firmware update path intact. We do not sell refurbished stock as new, and we do not source grey-market units.
Will MA-QSFP-40G-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, POs from qualified organisations, net terms on approval, and banded pricing once the quantity is worth banding. Send the number and we will price it properly.

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.
