Does the WS-C3750-12S support both single mode and multi-mode fiber runs simultaneously

I have a new building to add to our campus and I have been encouraged to run single mode fiber. All of my other buildings are connected with multi-mode fiber. I just want to make sure i will not have an issue if I run single mode to the new building with SM SFP's.

Thanks

Hello Snicholson1,

each port is a different matter regarding the physical layer you can have different ports using SM and MM fibers on the same device with no issues.

A single port can use SM EXOR MM fiber depending on the installed SFP

Hope to help
