Product overview
Part number CPAK-100GE-LR4 identifies this Cisco 100GBASE-LR4 CPAK transceiver, 1310nm CWDM4, 10km SMF, LC duplex. 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.
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
Quoted and supplied against CPAK-100GE-LR4 specifically, so what arrives is what your build sheet asks for.
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.
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 CPAK-100GE-LR4 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 CPAK-100GE-LR4 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.
