About the SFP991-1LH+ SCALANCE X accessory, Plug-in transceiver SFP991-1LH+ 1x 100 Mbps LC port, optical; single-mode optical up to max. 70 km.
The Siemens 6GK5991-1AE00-8AA0 SFP991-1LH+ is a 100 Mbps SFP transceiver for SCALANCE X switches, with a single LC port running 100BASE-LX over single-mode fiber for 12 to 70 km reach at 1550 nm. It carries FM and ATEX hazardous-location approval, CCC Ex marking for China, and French marine classification society (BV) certification for shipboard installations.

Selection Notes
Specify the SFP991-1LH+ when a link has to cross 12 to 70 km of single-mode fiber, well beyond the multimode SFPs in the same family; its -5 to 0 dBm transmit power and -34 dBm receiver sensitivity give it the optical budget for that distance, with a minimum 3 dB attenuation requirement to avoid receiver saturation on short single-mode runs. Marine classification and CCC-Ex approval make it the choice for shipboard or Chinese classified-zone links, not just long distance.
