The OCP link loss is 3.5 dB @ 500m, which would be 9.5 dB @ 2000m. The MSA is 5 dB @ 2000m, so where is the additional loss coming from in the OCP spec? Diffe

The OCP link loss is 3.5 dB @ 500m, which would be 9.5 dB @ 2000m.
The MSA is 5 dB @ 2000m, so where is the additional loss coming from in the OCP spec? Different connectors?
- ADefenestrator 10y agoIt's coming from loosened tolerances. Higher/lower temperatures may mean higher loss. I'm assuming there's a bit more tolerance in the alignment of the up optics/connectors as well. So, if you get lucky it might well be 5db@2km, but it's not guaranteed/required by spec.
