I have a 1Gbps link working fine at -21dBm. About 4 miles using 20km
modules. The next pair, pretty much same distance is at -10dBm. So
something is obviously wrong with that first pair or a splice somewhere.
These modules (MikroTik's and the FiberStore equivalent) will unlock at
about -31. -24 is probably all I'd tolerate. 10Gbps I'm sure needs a
little bit more budget.

Do you know the approx. route distance?
Was otdr shot on that line? Probably was by someone, but can you see
if they have record?
Or get a local crew to shoot it and tell you the details.
Do you remember what the SFP module was reporting?
I have a 40km laser link between two CCRs and it should be able to
make it easy, but there is loss and the logs on the CCR show that it
has issues.

*Subject:* [AFMUG] Mikrotik SFP+ 10GB
Wondering if anyone has guidance on what is an acceptable receive
power level that a CCR will report on an SFP. I currently have an
SFP+ module that is reporting a -18. This is a 40KM module�I
originally put in a 20KM module and it was reporting a -40. I was
getting only a one way link. The path I estimate is about 20KM that I
am linking�and I�m unsure of the quality of splicing�it is dark fibre
I have from a municipality�been running 1Gbps on 20KM SFP�s until now.
Thanks!
Cheers,
