One solved question, so you can see how these are marked
What is the maximum channel length specified for 1000BASE-T over standards-compliant balanced twisted-pair cabling?
100 meters
1000BASE-T supports a 100-metre channel, including the horizontal cable and patch cords. Other copper Ethernet PHYs and cable categories can have different limits, so 100 metres is not a universal rule for every copper technology.
