I would like to use a RB2011/CCR with SFP modules
to use a more than 20km singlemode fiber link.
Anyone can suggest a working SFP module for such distances (30-40km)?
Look for 1000Base-EX or 1000Base-ZX SFP’s.

Would it better for you to talk to a greater telephone service provider or internet service provider that is able
to let you rent a fiber cable and you only need a solution for the “last mile” from there DSLAM to your endpoints?
I mean if this is for outdoor usage you should dig the fiber cable into the earth and it should be also owns a shroud
against mice, rats or smaller animals and water protection! And in my poor opinion it should even more then one
SFP cable related to the circumstance, that one cable can be broken or having a failure and then the whole uplink
is dead!!! So it is better to set up more then one SFP cable perhaps something like 2 or 4 and then setting up an
LAG (LACP) because if one cable is failing then you have even enough more uplinks and throughput!
On the other side this is not a cheap project, a cable such like this, with a sufficient shroud and protection is
very high pricing! 100 meters for 120 € here in Germany and it should be even more then you think before related to
the circumstance that you need to dig it under the earth with a deep minimum of 80 centimetres, and in an S-form.
So you can count 10% - 20% percent on top of the length of the entire cable.
Look for 1000Base-EX or 1000Base-ZX SFP’s.
I consider to the tip of onnoossendrijver, it will be the best solution for this.
Ever tried to rent a (dark) fiber trunk and tried to make a business using LACP with four fibers where only the capacity of one is needed!!!???
Where at the initial thread is something written over the dark fiber?
Having one fiber line and this is faulty is like no fiber line!
Ever tried up to follow another different user here in the forum and not me?
I hope you meant ‘thread’, not ‘threat’, even when ‘post’ would have been the correct choice. Otherwise we’d better get us some bodyguards. The point is, nothing was mentioned. You just started to make things up out of the blue.
And don’t go on that paranoia train. Surely noone wants to follow you on that trip.
