Cisco SFP Question

[enajin]

Good evening folks, question for you:

Am I crazy, or does Cisco not have a 10G LC mm SFP that that can also be adjusted to handle 1Gb/100Mb/etc. ?

We have a large project at work that is fully 10G LC fiber; however, we want the capability to connect to 1Gb devices. All the connectors we have Cisco 10G-SR-S which are locked in at 10G and not connecting with slower 1Gb devices. I pop in a 1Gb gbic and it works perfectly, hoping there is an SFP that can do it all.

There is no SFP available like that in the Optic level SFP, you may have Ethernet-based.

it is a bit disappointing for you, but that is Truth.

All Cisco-branded optics are made by OEM like Finisar or Avago/Broadcom. 

No manufacturer has produced a multi-speed optics.

BTW, like the others, I do not recall there being any multi-speed optical transceivers, but, although not directly germane to your question, there are tunable DWDM transceivers, more info: Tunable Optical Transceivers
