Strange, I have both 450i and 450m running gigabit with no errors.  Using 
“Cambium sync” though.

 

So basically you’re saying the GDT version is better for data integrity?  And 
only for Cambium radios?

 

What about surge protection, it looks like it clamps all 8 wires at 90V to 
ground, but doesn’t try to clamp the differential voltage at some lower voltage 
like the other version?  I’m not sure how much of a problem that might be.

It doesn’t mess up Cambium.  Cambium can have frame check and crc errors with 
nothing more than plain cable.  Adding solid state surge suppressors causes 
problems for some reasons.  100% gas discharge tube cures that.

Sean, what do you find is the advantage of the CAT6-APC over the GIGE-APC-HV?

Hi Eric,

 

yes the new Cat6 gas tube version is what we use for 450i and 450m

What surge arrestors are you using with the 450m 5ghz? Is that the new CAT6 gas 
tube version?
