Re: [AFMUG] Mikrotik SFP+ 10GB

[Adam Moffett]

I wish they (everybody) would do something different with cable glands 
where the SFP slot is.  You end up having to replace the cable gland 
with a conduit fitting and build something to house the breakout.  I 
wonder if they should just put a cap over that SFP port, and then sell 
an interconnect box as an accessory that can attach to it.

Faisal,

Thanks for the great explanation.

And I agree, that every sfp module seems to have a different 
“personality” in terms of strength. We have seen this in a number of 
occasions with MM fiber. I have been buying my SFP modules from a 
company in California called ROBOFIBER… the quality is good, and 
pricing is not bad.  I do use some Maxxwave, Mikrotik and Finisar as 
well.  In fact, I can’t believe how much we have started moving to 
fiber over the past year…..times have certainly changed!

Let me see if I can try to clear up some confusion and help in sorting 
this out.


The optics, have TX and RX lasers... The TX will Transmit the Laser, 
and RX will Receive the Signal.


You have the look at the MFG Specs to see what is the TX power and 
what is the RX sensitivity.


Typically you need to have 5-7db of signal margin to have a link.

Now, each fiber connector has a 'Loss', each fiber cable has a signal 
loss rating this is a figure you can ask the Dark fiber supplier 
to provide to you...


Irrespective of whose fiber it is, when it was installed, or when a 
contractor worked on splicing it, they would have produced a 'loss' 
report.. e.g.  20 mile link is expected to have X db of Loss.


So, on paper, one would do the calculations as follows =  TX signal - 
Loss of all connectors and cable = RX Signal expected.


This RX Signal needs to be 5-7db higher than the RX Sensitivity figure 
of that Optic module for a good solid link.


Now, no two modules put out the same power, or have the same 
rx-sensitivity... there is always a certain amount of variation


Now, no two modules rated for the same distance from two different 
mfg.  have the same set of TX & RX Specs.


So it is ideal to have a light meter (you can get one for as low as 
$50 from Ebay, Fiberstore etc, don't worry about having a cheap meter, 
having one is better than having none).


This way one can measure the light coming out of the Optics and what 
is being received from the far side.


One can use a relative test to measure loss across a cable

Each SFP will have that range in their specifications.  Most of the time it
will say it under minimum receive power.

Re: [AFMUG] Mikrotik SFP+ 10GB

[George Skorup]

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.

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.

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,
