[FIOS] Is it ok to have the Frontier ONT (Alcatel I-211M-L) outside in FL?

Frontier installed the ONT (Alcatel I-211M-L) outside the house (inside a weather sealed plastic box), it gets direct sun light for almost 8 hours (if not more) every single day, the other option is inside the garage (where the ONT AC adapter is), but it is usually hotter than outside. Would it be better to install the ONT inside the house where there is Air Conditioning (AC)? I can't imagine what temperatures there are inside the ONT itself when outside is 95F+ almost all day. What are the specs regarding outside temperature for the Alcatel I-211M-L? Any advice or link to the ONT specs will be appreciated, thanks NOTE: I am in Sarasota, FL
