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.

I've had some issues with Occam compatible SFPs in RB260gs units -
they would work, but you would have to unplug them and plug them back
in while the unit was powered up to get them to link. 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.

I've heard too many stories of modules "working" but not working.
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. :)

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...

Nate,
If you are not able to locate the MM Bidi SFP's,
you might want to try the
SMF Bidi on your MM fiber run..
Take a look at this:-

Subject: [AFMUG] Multimode BIDI
Is there a MultiMode BIDI SFP? 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
