2M Optics too hot?

We recently started to swap out our 1gb copper for 10gb optic SFP's for our uplinks and I am worried they may be running to hot. The cables we are using are a 2m OM1 MM Jumpers paired with SFP-10G-SR. The current looks alright running at around 8, but both the TX and RX are at 0.55/0.58. I have never ran cables this short or used SR optics before but I know with the LR optics I have used in the past that was definitely a bit to hot.

Having said all that my questions are: Will these levels be problematic, and if so, how long of a cable do you think I would need to lower that to a better level?
