Siemens 6GK5991-2AD00-8AA0 Media Module MM992-2

The Siemens 6GK5991-2AD00-8AA0 MM992-2SFP media module adds two SFP ports to SCALANCE X modular Ethernet switches, enabling flexible fiber connectivity in industrial networks. Designed for the SCALANCE X family, this two-port module accepts a range of SFP transceivers to support different fiber standards and link distances. Supported transceivers include SFP991-1, SFP991-1LH+, SFP991-1LD, SFP992-1, SFP992-1LD, SFP992-1LH, SFP992-1LH+, SFP992-1ELH, and SFP991-1ELH200. Use cases include linking SCALANCE X devices across factory floors, connecting to fiber backbone networks, or extending an automation network with fiber‑optic links. The MM992-2SFP module is documented for this order number and is part of Siemens’ media‑module lineup, providing a two‑port fiber/media interface to support scalable industrial Ethernet deployments.
