Product overview

FTLX8571D3BCL-NU is a Finisar 10GBASE-SR SFP+ Transceiver Module (MMF, 850nm). 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

FTLX8571D3BCL-NU is what is quoted and FTLX8571D3BCL-NU is what ships; where an alternate code is genuinely the same part we name it rather than swap it silently.

Volume pricing

The listed price is per unit; tiered pricing applies at quantity and purchase orders are accepted.

Answered by a human

A quote comes back with the reasoning attached, including the cases where we think you should buy something else.

Questions buyers ask about this part

Is FTLX8571D3BCL-NU 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 FTLX8571D3BCL-NU 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.
