Yes, it does, Because they equip the same 15km single-mode fiber optical interface. But, please have noticed that the ISW-511S15 operating temperature is from -10 to 60 Degree C only.

Different operation temperature.
　　ISW-500 / 800: 0 to 60 Degree C
　　ISW-501T / 801T: -40 to 75 Degree C
With T model, it shall runs well in harsh environment.

No, you can’t. When the X-Ring function enabled, the RSTP must disable. The X-Ring function and RSTP function cannot active on ISW-1022MPT at the same time. If need to co-work with RSTP, please enable Dual Homing function.

Yes, it does, please upgrade the firmware to version v1.0 kernel v.2.57 or later with ISW-1022M, ISW-1022MT or firmware versionv1.0 Kernel v1.90 with ISW-1033MT first.

The major differences are the number port of the fiber interface and the fiber-optic distance. The difference is as table above.

The major difference is the operating temperature range. ISW-511 / ISW-621 series temperature range is from -10 to 60 Degrees C. The ISW-511T / ISW-621T Series is from -40 to 75 Degrees C.

No, the IFT-802T could not connect to IFT-802TS15, because IFT-802T equipped 2km multi-mode fiber optical interface but IFT-802TS15 equipped with 15km single-mode fiber optical interface. Our suggestion is let IFT-802T connect to IFT-802T or IFT-802TS15 connects to IFT-802TS15.
