You need a gigabit fibre link out to the next site, the other end of the campus, or down the road — and it's got to survive the heat in your plant or substation. This D-Link transceiver is rated to 85°C ambient and pushes 1000Base-LX over single-mode fibre (1310nm) for up to 10km. Drop it into any SFP slot on your DIS-series switch, connect your OS2 cable, and you've got a solid gig link that holds when the ambient climbs past what an office-grade module can take. Single-mode, long reach, industrial rated. That's the whole pitch
