Product overview
Finisar lists FTLC1154RDPL as a 100GBASE-LR4 QSFP28 Transceiver Module (SMF, 1310nm, 10km). 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-LR4. Tell us both switch models and we will confirm compatibility before it ships.
We return an itemised quote within 48 business hours, and we say plainly when a part is constrained rather than quoting a date we cannot hold.

What you get ordering this from us
Ordered by part number
FTLC1154RDPL is what is quoted and FTLC1154RDPL is what ships; where an alternate code is genuinely the same part we name it rather than swap it silently.
Compatibility checked
We confirm the part is supported on your platform before it ships, rather than leaving the check to you.
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.
Questions buyers ask about this part
Is FTLC1154RDPL genuine and is the warranty intact?
Yes. It ships new in Finisar 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 FTLC1154RDPL 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, since both ends and the switch have to agree.
