Product overview
Part number SFP-10G-LR identifies this Cisco 10GBASE-LR SFP+ Transceiver module, 1310nm single-mode fiber, 10km reach, LC duplex. 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.
Ask for the datasheet and firmware notes with the quote; we would rather you check our claim than take it.

- MSPs holding spare optics against a customer SLA
What you get ordering this from us
Ordered by part number
SFP-10G-LR is what is quoted and SFP-10G-LR is what ships; where an alternate code is genuinely the same part we name it rather than swap it silently.
Reach checked against the run
Fibre type, connector and distance are checked together, so the optic suits the path and not just the port.
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 SFP-10G-LR 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 SFP-10G-LR 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. 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.

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.
