Product overview
This is the Finisar / Coherent finisar/coherent 1000BASE-T copper SFP Transceiver (1.25Gbps, RJ-45, up to 100m), order code FCLF8522P2BTL-DL. 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.
The listed price is per unit and current; tell us the quantity and we will confirm what it holds at before you raise the order.

What you get ordering this from us
Ordered by part number
FCLF8522P2BTL-DL is what is quoted and FCLF8522P2BTL-DL is what ships; where an alternate code is genuinely the same part we name it rather than swap it silently.
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.
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.
Questions buyers ask about this part
- Is FCLF8522P2BTL-DL 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 FCLF8522P2BTL-DL 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. We quote against a purchase order and hold the price for the quote period, with tiered rates at quantity. Net terms are available once the account is approved.

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.
