About the SFP991-1A SCALANCE X accessory; Active plug-in transceiver SFP991-1A; 1x 100 Mbps LC port, optical; multimode glass up to max. 5 km (with OM2++ fiber)
The Siemens 6GK5991-1AD00-8GA0 SFP991-1A is an active 100 Mbps SFP transceiver for SCALANCE X switches, with a single LC port running 100BASE-FX over multimode fiber up to 5 km at 1310 nm. It is rated -40 to +95 degC operating temperature and carries hazardous-location approval including CCC-Ex for Chinese installations.

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.
