My Trango issue is also with Multimode....not sure if that's a
coincidence.
As reported by the CCR, tx is -7dbm, rx is -6dbm.
(Eric Kuhnke will now scold me and say I should be using SM, but the
SFP's with industrial temperature ranges are still a lot cheaper MM.
And it's only going a few hundred feet.)

I’ve seen that same issue as you describe it between
CCR1036/CCR1016/CCR1009 and Netonix switches. Tik says fiber is up at
1Gbps but no rx traffic. Netonix detects the cable is plugged in but
can’t get any traffic through. Toggling SFP to inactive/active usually
fixes. Used Fiberstore Generic, Mikrotik, and HP SFPs in the Mikrotik
– no improvements one over the other. Netonix seems to prefer HP SFPs.
Doing things like turning flow control on/off or changing speed
negotiation settings on the Mikrotik can induce this problem
*sometimes* - depends on what mood it’s in. No rhyme or reason when it
fails at other times – toggling usually fixes it though.

Subject: Re: [AFMUG] CRS with sfp lockup
I'm not saying this is the same problem....but I have a situation
where a Trango Apex Lynx loses link to a CCR 1036. The SFP interface
on the router says there's link, but the SFP interface on the Trango
says there isn't. The problem (in my case) occurs any time the Trango
loses power. I can restore service by rebooting the CCR, unplugging
and reconnecting the fiber cable, or disabling and re-enabling the SFP
interface. In this case I didn't have a good picture of what was
happening at first because when it was happening I didn't have remote
access to see the condition of everything.
The Apex Lynx has the JDSU SFP module sold by Trango. I've duplicated
the problem with 4 different SFP's in the CCR (Mikrotik brand,
Maxxwave, JDSU, and Finisar), but I haven't tried changing the SFP in
the Trango. I don't know how common this issue is....it only became
apparent after a UPS failed.

Subject: [AFMUG] CRS with sfp lockup
I have a mikrotik CRS210 with a non-mikrotik sfp which locked up last
night, Not sure if it was the CRS or the sfp...
Anyone encountered this and have a solution?
