(1) There are two main materials for lightning interface connecting wires. One is the cable lightning connection line that has been published. It can not only provide dual-channel bidirectional transmission bandwidth of 10Gb/s, but also provide power supply of 12W, which can directly drive passive mobile devices. In addition, one version of the cable is made of optical fiber. Theoretically, the transmission speed of optical fiber can reach 100 GB/s, which is 0/0 times that of wired version and 20 times that of USB3.0 interface. It will be the best choice for equipment with extremely high transmission speed requirements.
(2) The maximum transmission bandwidth of USB 3.0 is 5.0Gbps. USB 3.0 is a USB specification initiated by Intel and other companies. Now it has been renamed as USB 3. 1 gen 1 by USB IF.
(3) The fastest transmission speed of Ethernet is10Gb/s.1.25Gb/s. Ethernet can use various connection media, including coaxial cable, twisted pair and optical fiber. Among them, twisted pair is mostly used to connect the host to the hub or switch, and optical fiber is mainly used for cascading between switches and point-to-point links between switches and routers. Coaxial cable, as an early main connecting medium, has been gradually eliminated.
(The maximum transmission speed of FireWire is 400Mbps. FireWire interface is a high-speed transmission interface developed by the development alliance led by Apple, and the data transmission rate is generally 800Mbps. FireWire is a trademark of Apple. Sony products call this interface iLink.
(5)wifi is generally 54Mbps, and the maximum should be 600Mbps. Wi-Fi is a technology that allows electronic devices to connect to a wireless local area network (WLAN), usually using 2.4G UHF or 5G SHF ISM radio frequency band. Connecting to WLAN is usually password protected; But it can also be open, allowing any device within the WLAN range to connect. Wi-Fi is a brand of wireless network communication technology, which is owned by the Wi-Fi Alliance. The purpose is to improve the interoperability between wireless network products based on IEEE 802. 1 1 standard.
