I know.

But my here pros and cons:

                       100Base-TX                100Base-FX SC
                        Ethernet                  Multi-Mode

1) Lengt                 =<100m                        2km
2) Lightning hits       requires                       ---
                       protection
3) Env.Temperatur    -40°C no problem                 ???
4) Price                =< 0,50€/m             arround 120€/100m
                                                   configured
5)                   easy to find switches    Most only professional
                      with external power    switches with integrated
                            supply              Power supply (230V)

I found the "HP ProCurve 1600M" (16-port. under 100€) and the 4-port
"HP J4112A 100Base-FX Module" (approx. 50€). This would be perfect,
except for the Power Supply.

The question is:

Is it possibel to replace the 230V Power supply by a DC-DC-Inverter?
Recom and Traco have a huge sortiment...

Or use simply my D-Link 5/8-Port GreenSwitches and use a load of
TP-Link MC100CM in my "Server Bunker"?  On the other End I could
use the Microsens MS453111 which has 7 Ethernet and one FX ports.

Thanks in advance
