Each USB Type-C cable has its own functions and uses, these cable types have their own characteristics and uses, users can choose the appropriate Type C cable for their own equipment according to their needs.
(1)Passive cable: This cable is mainly used to transmit signals that comply with the USB2.0 standard, and it does not contain any integrated circuits. Passive cables are also not available for power supply protocols, but can allow downlink ports to advertise and provide additional power for current mode operation.
(2)Electronically labeled power cable: This cable is capable of running at all USB3.1 speeds and contains integrated circuits for handling electronic transmission communication protocols. Electronic marking allows for role switching, alternate mode selection and enhanced power options. EMA cables are electronically tagged and can support the USB PD protocol.
(3)Dynamic power Management cable: This cable has the same basic circuitry as an electronically labeled cable, but with additional signal repair capabilities. Dynamic power management cables require active power cables to be managed to extend cable length to support high power transmission and high-speed data transmission.
