I think I’ve seen that a couple of times with the RB260GS units as well. Mostly during a brownout or power spike.
Not all of them, just one or two out of hundreds. Had to re-rack the SFP to get them to connect. This happened with the Mikrotik branded ones, FiberStore branded ones, and I think the generic ones too.

So if the Mikrotik loses power, the link goes down until you pull the SFP again. Not sure if that was just with that particular SFP model though, as I haven't had any problems with the generic units. I've also had an issue with Mikrotiks linking to a planet switch, but that was some incompatibility between the actual devices, not the SFPs.

It's detected, you get link status and all that, but end up with packet loss and/or CRC/FCS errors. The only SFPs I've used with Routerboards so far are MikroTik branded. I have one talking to a Ciena 3930. And another talking to a dumb media converter. Those both work fine. Was it Jason that was having issues getting them to talk cleanly to a Cisco or Planet switch? I really don't trust any MikroTik product to be very reliable, but they're cheap so we can have lots of spares. :) On 5/27/2015 9:28 PM, Faisal Imtiaz wrote: will it work in a MikroTik!? Why shouldn't they ? To the best of my knowledge MT don't use locked Optics.. additionally SFP's & SFP+'s are a standard .. There are a few options on the modules (mostly for reporting light levels and temp etc) that may or may not work...

I need to run a connection across a warehouse, they have 3 pair of multimode fiber, but all 3 are already in use. They won't let me tunnel connections together, because that would be touching 'their' network, but I could probably talk them into using only a single Strand, to let me have one. Googling around hasn't yielded any results yet, but I'm still searching. Any other passive deivce to get 2 connections on one/pair Multimode fiber? Nate
