Silaba Mpasu Physical Networking Unit 6 Exercise 1 Connector Installations Twisted-pair cable On a TWISTED PAIR CABLE I chose to install an RJ-45. This is the standard Ethernet connector for most systems used today. I would first measure out the length of cable that I would need. I would then use a wire cutter to cut the length that I need‚ leaving enough room for corrections and to open the wire. I would then use wire strippers to remove a small piece of the outer most jacket. I would then choose
