All depends on the chipset used and how well and propper they designed there pcb and layout there components..
100 meter 1,5G can be intermitting even with the right cable and quality converters..
It could go nicely but my thumb role these days is
"Over 75 meters HD, Go fiber"
"Over 30 meters 4K, Go fiber"
And Sommercable Vector 600 is very good.. It is up to spec even for 12G-SDI.
