I am having a hard time trying to figure out which SFP or SFP+ that I need to purchase for a couple of 3750X that I have.
There will be SMF ran between the two and I will be utilizing an existing fiber run. I am including two photo's I have of the fiber in case it will help identify its properties.
I am hoping that someone who knows a bit more about fiber is able to look at this and tell me which SFP module will support this particular fiber run.
The following is the link to the 3750-X supported SFP/SFP+.
In case it matters, my two 3750-X's both have the C3KX-NM-10G module.

Fiber 1: SC 1310nm(A) = -0.09dB / SC 1550nm(A) = -0.42dB / SC 1310nm(B) = -0.07dB / SC 1550nm(B) = -0.40dB
Fiber 2: SC 1310nm(A) = -0.03dB / SC 1550nm(A) = -0.09dB / SC 1310nm(B) = -0.01dB / SC 1550nm(B) = -0.07dB
06/07 OFCP (UL) c(UL) 6 SMF TERAFLEX A1

here is the compatibility sheet
If you wish to use 10Gb speed then you will need SFP-10G-LR. This is what I would use because of the NM-10G module in the switch. The GLC SKUs are for 1Gb speed but of course are less expensive.
I hope this is helpful.
