Selection Notes
The SFP991-1A's -40 to +95 degC operating range and CCC-Ex hazardous-location mark fit installation sites that run hotter than a typical cabinet or fall under Chinese classified-zone requirements, where a general-purpose 100 Mbps multimode SFP's approvals and temperature spec would not apply. Its optical budget (100BASE-FX, 5 km multimode) is otherwise a standard 100 Mbps link, so the reason to specify this part is the ambient rating and the certification, not extra reach.
