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?
I’m using this SFP in my RB2011UAS-RM:
sfp-connector-type: LC
sfp-link-length-9um: 20000m
sfp-vendor-name: Mikrotik
sfp-vendor-part-number: S-31DLC20D
sfp-vendor-serial: SG31242301XYZ
sfp-manufacturing-date: 14-06-28
sfp-wavelength: 1310nm
sfp-temperature: 59C
No problems so far.
It’s about one year I’m using mikrotik sfp even on Cisco switches ..no problems encountered
