I have a problem with connection between two RB's 2011 through SFP optical module.
I have bought s-53lc20d modules, to connect over 1 fiber pigtail. These are modules recommended to connection between RB2011 by Mikrotik: http://routerboard.com/S-3553LC20D
RB's fw is 6.34.3 on both sides.
Connection is not up.
Changing 'auto negotiation' on sfp module to OFF makes status 'up', but there is no tcp connection.
I see all optical parametres (tx, rx level). FO cable is 100% ok, I have tried on many pigtails.
IPs are set, but there is no physical transmission. I cannot ping to other side.
Turning to ON 'auto negotiation' makes disconnection every time.
I have digged over the forum, there are some posts, but no one is with working solution.
Can anybody give a working hint?
