Description

The Siemens SFP991-1LD (6GK5991-1AF00-8AA0) is a single-mode SFP transceiver module for SCALANCE X Industrial Ethernet switches, providing one 100 Mbit/s optical LC port with a transmission range up to 26 km via the 100BASE-LX method. It runs across a -40 to +85 °C ambient range, matching SCALANCE X switches rated for outdoor cabinets or unconditioned enclosures.

Selection Notes

This is the single-mode 100 Mbit/s variant in the SCALANCE X SFP portfolio: pick it over a multi-mode 100 Mbit/s SFP once the run exceeds roughly 2 km, since the 1310 nm single-mode path is rated to 26 km. The -40...+85 °C window lets it sit in the same enclosure as SCALANCE X switches specified for unheated or outdoor cabinets without a separate temperature derating check.

Applications

Extends optical uplinks between SCALANCE X switches in ring or line topologies once copper's roughly 100 m reach is exceeded - linking switch cabinets between buildings, along long conveyor or process lines, or across plant sections on a single-mode fiber backbone.
