Product overview
This is the Finisar 1000BASE-T copper SFP Transceiver Module (100m), order code FCLF8521P2BTL. Optics have to match at both ends and are frequently vendor-coded, so a module that is electrically correct can still refuse to link. Tell us both switch models and we will confirm compatibility before it ships.
Ask for the datasheet and firmware notes with the quote; we would rather you check our claim than take it.

What you get ordering this from us
Ordered by part number
Quoted and supplied against FCLF8521P2BTL specifically, so what arrives is what your build sheet asks for.
No substitutions without asking
If we cannot supply the exact code we tell you what we can supply and why, rather than shipping an equivalent and letting you find out.
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 FCLF8521P2BTL 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 FCLF8521P2BTL 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.
