As for the OP’s question, I’ve run Cisco OEM, Brocade OEM, and a number of different 3rd party SFP/SFP+s in the few 
Arista switches we operate with no issues. Arista OEM is likely the same 2-3 vendors that make or have made Cisco’s 
optics. It’s all been 10GBASE-SR, -LR, and 1000BASE-T, though. No 40GbE or 100GbE.
