Hi,

Yes, SR in the part number stands for short reach and that is used with multimode fiber.

If you had SFP-10G-LR (long reach) than you would have to use single mode fiber.

Hi Pat,

As mentioned above SR does in fact indicate MM fiber. Make sure you utilize lazer-optimized fiber (50 micron OM3/OM4). Using 62.5 micron decreases usable distance and in some cases does not work at all.

Old Thread, but I had the exact opposite question - 

Can you use Single Mode Fiber with a SFP-10G-SR ?
