Product overview
The Cisco 4.25G fibre channel SFP medium-reach Transceiver Module (SMF, 1310nm, 4km) is supplied under part number DS-SFP-FC4G-MR. 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.
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
DS-SFP-FC4G-MR is what is quoted and DS-SFP-FC4G-MR is what ships; where an alternate code is genuinely the same part we name it rather than swap it silently.
Checked against the fabric
We confirm firmware level against the switch and the array vendor compatibility matrix before the card ships.
WWPNs supplied ahead of delivery
Where we can, port identifiers come with the paperwork so zoning can be raised before the host is racked.
Questions buyers ask about this part
- Is DS-SFP-FC4G-MR genuine and is the warranty intact?
- Yes — new and sealed, with the Cisco warranty and the firmware update path intact. We do not sell refurbished stock as new, and we do not source grey-market units.
- Will DS-SFP-FC4G-MR 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. 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.
