Product overview
The Cisco 4G fibre channel longwave SFP Transceiver Module (SMF, 1310nm, 10km) is supplied under part number DS-SFP-FC4G-LW. A card that fits the slot may still be unsupported by the array vendor's compatibility matrix, which is the document that decides support cases. We check that matrix, not just the slot.
Priced per unit, with tiered pricing at quantity — send the number you need and we will come back with the banded price.

What you get ordering this from us
Ordered by part number
DS-SFP-FC4G-LW is what is quoted and DS-SFP-FC4G-LW is what ships; where an alternate code is genuinely the same part we name it rather than swap it silently.
Answered by a human
A quote comes back with the reasoning attached, including the cases where we think you should buy something else.
Checked against the fabric
We confirm firmware level against the switch and the array vendor compatibility matrix before the card ships.
Questions buyers ask about this part
- Is DS-SFP-FC4G-LW 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 DS-SFP-FC4G-LW work in my server?
- Send us the server model or service tag and we will confirm before you order. Part numbers alone do not always settle it — firmware revision and platform generation matter, and this is the check that prevents a return.
- 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.
