Questions and answers

Is this the same as a Cisco DS-SFP-FC2G-LW?
It is a compatible module built to the same 1/2 Gbps Fibre Channel LX spec: 1310nm, 10km over single-mode fiber, dual-LC. It is not a Cisco-branded original.
Does it support DDM?
No. This module has no digital diagnostics, so you cannot read optical power, temperature or voltage through the switch.
What fiber and connector does it need?
Single-mode fiber with dual-LC connectors. It reaches up to 10km at 1 or 2 Gbps.
Will it work in my Cisco switch?
Compatible SFPs generally work in Cisco Fibre Channel ports, but some IOS/NX-OS builds warn on non-Cisco optics. Check your switch's unsupported-transceiver behavior before buying.
Is it TAA compliant?
No. The module is not TAA compliant, so it may not qualify for government or federally funded purchases.
When is it cheapest?
Only one store lists it new, at $104.00 at FluxLight as of November 6, 2026. With a single seller, there is little price movement to wait for.
Where is the Cisco DS-SFP-FC2G-LW Compatible 1/2Gbs Fiber Chan-LX SFP Transceiver Module cheapest?
At FluxLight, for $104.00, as of our latest check.
