下面是客户需求的，哪种对线可以达到1G的传输速度?

The second if for signal 1G bit so twisted pair is probably the way to go. The connector must be for cable mount or mounted on a cable and IP 65 rated. The connector must come in both a male and female type both for cable mounting. The connector must comply with CE and possibly UL or ETL/CETL or it could also be two different connecters, one for EU and one for US if the price is too high for the UL connecter
