This paper discusses SNR measurements and calculations when applied to Silicon Photomultipliers.
The Technical Note was produced in 2012 so the figures quoted are relevant to SensL's M-series SiPMs.
SensL's C-series SiPMs released in July 2014 have ~5% of the Dark Count Rate as do the J-Series devices released October 2015. A correspondingly higher SNR may therefore be assumed.
