SFP module for extended-temperature SCALANCE X deployments
The Siemens 6AG1992-1AM00-7AA0 is a SIPLUS NET variant of the SCALANCE X SFP992-1LD, built on the standard 6GK5992-1AM00-8AA0 with added conformal coating for operation in condensing or corrosive environments. It provides one 1000 Mbps LC optical port on single-mode fiber, with a 1310 nm wavelength and a reach of up to 10 km.
Thermal and reliability profile for harsh environments
The conformal coating protects against moisture, dust, and chemical exposure — the key differentiator from the base 6GK5992-1AM00-8AA0 for applications in washdown zones, outdoor cabinets, or desert PV plants where condensation cycles are daily. MTBF is listed at 600 a, consistent with industrial SFP reliability expectations for single-mode optics at these temperatures. Storage, transport, and operating temperature ranges all match at -40 to +85 °C, simplifying logistics planning for spares held in non-climate-controlled warehouses.
The SFP module measures 14 mm wide, 57 mm deep, and 9 mm high, with a latched fastening method for secure retention in SCALANCE X switch SFP cages. IP20 rated — suitable for use inside a control cabinet or enclosure; the conformal coating provides the environmental protection at the board level. The LC optical interface accepts standard single-mode patch cables with LC connectors; the transmitter output is -3 dB (max) to -9.5 dB (min), and the receiver input maximum is -3 dB.
