The Siemens 6AG1992-1AL00-7AA0 is a SIPLUS NET SCALANCE X SFP992-1 SFP module for industrial Ethernet switches. It provides a 1000 Mbit/s optical interface over multimode fiber up to 750 m using an LC connector at 850 nm. Rated MTBF of 670 a puts this SFP in the high-reliability tier for continuous links — the sort of figure that keeps spare pull-tickets off your board for years. Operating range runs -40 to +85 °C, with the caveat that +85 °C is permissible only for 16-hour bursts. That matters if the module sits in a tightly packed, non-air-conditioned cabinet that sees afternoon thermal peaks.
Compliance & lifecycle
The product status is Active — no end-of-life horizon. This line remains a supported Siemens catalog item, so BOMs tied to it avoid last-time-buy pressure. CE marking is present; conducted and radiated emission meets EN 61000-6-4:2007 Class A, and immunity conforms to EN 61000-6-2:2005. Standard EMI paperwork for a control-panel install without special filtering. Enclosure is IP20, latched into the switch chassis — no screws or tools needed for removal.
Optical link budget
Receiver input sensitivity at -3 dB, transmitter output from -9.5 dB to -2.5 dB. The 750 m range is specified with multimode fiber. Dimensions: 14 W x 57 D x 9 H mm — fits any standard SCALANCE X SFP bay. No panel space consumed beyond the switch itself.
