•TDR theory to measure length of cat5e, cat6 and cat7 cable, coaxil cable, telephone cable

•Wiremapping with length and provide the distance to fault information

•PoE function: identify which pins are providing power and detect how much voltage

•PING function to test network performance, data packet, MIN&MAX time

•Quickly find the targeted cable without stripping isolation among unknown cables

•Hub blinks for locating network port by the flashing port light
