hi , i am trying to figure out the correct sfp for my scenario. currently my 2960x switch needs to connect to 3850 switch i want them both to connect at 10G Fiber.
i was thinking about using SFP-10G-LR or SFP-10G-LRM on both sides currently the fiber type 9 micron.
can someone help me in choosing the correct sfp the fiber will be single mode 9 micron

Hi,
You can rule out SFP-10G-LRM as this is for multi-mode fibre (62.5 or 50 micron)
Please see this link re SFP/SFP+ specs

Hi,
In addition to the link Alex provided (LR) means long reach for which you need single mode fiber. If the distance between your switches is less than 500 meters, you can simply use (SR) short reach optic which can use multi-mode fiber. The part numbers are;
SFP-10G-SR= Multi-mode
