Product overview
Part number CPAK-100GE-SR4 identifies this Cisco 100GBASE-SR4 CPAK transceiver, 850nm, MMF (up to 100m OM4), MPO connector. 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.
Tell us the deadline you are working to and we will say whether it is achievable before you commit to it internally.

Questions buyers ask about this part
Is CPAK-100GE-SR4 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 CPAK-100GE-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. 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, since both ends and the switch have to agree.
