Hi,
I’ve to combine MT with some licensed Equipment which has
Fiberoptic Gigabit Ethernet. As there is no MT-Equipment with
Fiberport I’ve to buy switches/converter with SFP or direct Fiberport.
Cabinets are not air-conditioned so a temperature range
-20to+50C is needed.
What do you use?
Thanks,
Stefan
The CLOSEST you can come to that is a PowerRouter 732, as they are reated up to 120F, the 1000s are only rated for 105F I belive. The 732 has a 2 port Fiber option as well. www.mikrotikrouter.com.
However, if you need the fiber but 1000 or smaller board will work, then I would suggest http://www.mikrotikrouter.com/fiber.asp as these will covert your fiber to Ethernet for MT boards 
Usually thhough, if you are running fiber, you need the processing power too though.
We use fiber converters from www.versatek.com, transition networks, and trendnet (available at newegg). Just pick something that works for the fiber type (sm/mm) and distance involved. Too high a power output is not desirable for a short fiber link.
Very good and reliable stuff from MOXA:

-40 - +70C !
Sind wir Kollegen ?
Nach meinen bisherigen Erfahrungen wäre ich sehr skeptisch, MT in einer industriellen Umgebung (hohe Verfügbarkeit ! ) einzusetzen. Aber nur Mut ..
English, please =)
and… we use RouterOS on core routers in production - it routes!
Ja ähh yes
I do not question that. But in case a casual user like me finds quite a few bugs/glitches himself, like
http://forum.mikrotik.com/t/pppoe-does-never-start-if-wan-disconnected-during-startup/25532/1
which is still not solved in 3.30, then I start to be suspicious. On top of that, my actual problem with hotspot-login, which is still ongoing. It took a long discussion to convince MT at least, that there is a problem.
Especially the glitch mentioned in
http://forum.mikrotik.com/t/pppoe-does-never-start-if-wan-disconnected-during-startup/25532/1
is one of those, which can happen in an industrial environment.
BTW, such special events I test carefully myself, because I have a little bit expirience finding the weak spots of SW:-)
For example, my first programs I wrote were installed in the factory for rubber/tires close to your hometown, Bobrusk. A few years ago
Or on a SM-4 in Chelyabinsk, in a steel rollers plant …

Of course, we might have different understandings of the term “The SW works”. For instance, one of my customers, from a big German airline, told me: “There is no such thing like “User Error””.
And he is right
I acknowledge, there are bugs in SW. But it should be a question of policy, to fix them ASAP. And even, in case there is only the suspicion of a bug, it should be carefully traced. Not simply to be “Put on Hold” until some more complaints show up. Or the user simply gives up, like me in
http://forum.mikrotik.com/t/pppoe-does-never-start-if-wan-disconnected-during-startup/25532/1 which still shows up on my MT-hot spot Test-PC only, fortunately.
So this hotspot-stuff is just a hobby of mine, but giving me the reasons to confirm: MT not for production use.
well, then it depends on your needs =)
for us, ROS is almost perfect maybe soon we’ll try to use bonding of gigabit links again, and last time we tried that we have faced full inoperability after a few hours… %)
I still prefer Routers with SFP port.
If you use a dummy FO Converter, the interface state which is connected to your Copper interface MT will always be up if the fiber link is down. And you create a black hole over there.
Unless you have a dynamic route over the link, or use keepalive monitoring on the other hop ip.
With SFP, this will never happens.
it depends on your converter. some of them bring the LAN down and some - not
… which is a MUST in industrial apps. Simply as a “safety net” also to catch the unforeseen problem.
But in general I have to agree on your opinion; simply because of the fact, the less parts you use, the less possibility of faults.
You only confirm my opinion
You’ve to work with MT-Boxes not the same way as you would do
with perfect engineered and totally tested equipment.
You have to use the functions you need, you’ve to test it before deployment
and you’ve to take care doing updates.
If you follow this rules you get a lot for the money. You can build
high-performance routers with low power requirements and small
footprint. If you’re afraid of hardware failure, buy a second
system as it’s cheap. Now we’re getting 11n by just pluggin in a
new wireless card. Ask your Canopy,xyz,… supplier for an 11n
Upgrade …
But this thread has an other subject 
Stefan
well, actually, I wasn’t sure about that hardware - I have a suspicion that one NIC was bad… so need to recheck again on tested hardware ))
