Selection Notes
Choose the SFP991-1 when the link runs on multimode fiber up to 5 km and 100 Mbps is enough bandwidth; its -24 to -14 dBm transmit power and -31 dBm receiver sensitivity are set for shorter multimode runs, not the longer-reach single-mode SFP variants in the same family. The 10-piece pack size fits stocking multiple SCALANCE X switch ports or spares from one order rather than buying single units.
