Hi All! I receive questions from various folks from time to time who need to take advantage of dark fibre runs > 20Km. I have already received confirmation from MT that none of their products currently support power required to deliver greater than LR modules, so I suppose that the only option is for some kind of third party switch or media converter would be required when using MikroTik routers at the endpoints? Here is a query I received this afternoon: "What are after is integrating a 45km Single mode dark fibre into our network, obviously mikrotik routers on each end. If we could push 10Gbps that would be awesome, however if we could obtain 2 or 3Gbps with a lot less effort that would most likely be the go to start with." Does anyone have any suggestions for the OP? (I suggested that he post here, but perhaps he's a bit too shy to post in a public forum, so I offered to ask on behalf ;) Any comments will be most appreciated! Cheers, Mike.
