Not sure about copper cable max throughput but VDSL2 ( the one unifi uses for high rise buildings) can support max up to 200 Mb/s (100Mb/s up and 100Mb/s down) or 200Mb/s downstream

VDSL2 permits the transmission of asymmetric and symmetric aggregate data rates up to 200 Mbit/s downstream and upstream on twisted pairs using a bandwidth up to 30 MHz. It deteriorates quickly from a theoretical maximum of 250 Mbit/s at source to 100 Mbit/s at 0.5 km (1,600 ft) and 50 Mbit/s at 1 km (3,300 ft), but degrades at a much slower rate from there, and outperforms VDSL. Starting from 1.6 km (1 mi) its performance is equal to ADSL2+.

While normal VDSL can support upto (55 Mbit/s down 3Mbit/s up)

Just to share with you guys if modem power adapter spoil already but dun want to wait for TM replacement..this is the connector size..
