We recently had an issue with an old SFP on a CCR1036 router. According to the output from RouterOS, the SFP was manufactured in 2004. So this SFP was replaced, but again with the same model from the same batch, i.e. it's again manufactured in 2004. The exact model is: SFP-1.25G-1310
And I was thinking that it's time for a refreshment. What kind of SFPs do you guys use on your Mikrotik routers and switches? Could you recommend any vendor?
I saw that Mikrotik is also selling their brand of SFPs, like http://routerboard.com/S-31DLC20D. Are they any good?
I also found two forum threads describing issues with S-31DLC20D, have you encountered any?
