[0035] Please refer to the following: Figures 1-6The data line 100 and the electronic device 300 are used in cooperation to enable the data line 100 to perform data transmission and charging for the electronic device 300. The data line 100 comprises a circuit board assembly 20, a transmission cable 40 and a housing 60. The circuit board assembly 20 comprises a first circuit board 22 and a pair of charging interfaces 24 connected to the first circuit board 22. The transmission cable 40 comprises an optical fiber data line 42 and a pair of power lines 46. The optical fiber data line 42 comprises an optical fiber line 421 and a shielding layer 423 sleeved on the optical fiber line 421. The shielding layer 423 is located between the pair of power lines 46 and the optical fiber line 421. The pair of power lines 46 are electrically connected to the first circuit board 22. The optical fiber line 421 is isolated from the first circuit board 22 by the shielding layer 423. The optical fiber line 421 is used for data transmission. The pair of charging interfaces 24 are used for charging external devices such as the electronic device 300. When the data line 100 is used in cooperation with the electronic device 300, the electronic device 300 is charged, the electronic device 300 performs data transmission with external devices through the optical fiber line 421, or the electronic device 300 performs data transmission with external devices through the optical fiber line 421 while being charged.

[0036] The electronic device 300 in the present application is, for example, but not limited to, a mobile phone, a tablet computer, a smart television, a smart watch, a VR head-mounted display, a vehicle-mounted display and other electronic products with a charging battery.

[0037] The internal line of the existing data line is made of copper wire or other metal medium. However, the data line made of copper wire has a limited bandwidth in use, and the highest bandwidth of the data line can only reach 100 Mbps in general, and has a large attenuation. In addition, the data transmission using the metal medium is easily affected by electromagnetic interference, and the rate fluctuation is large.

The data line 100 of the present application uses optical fiber wire 421 for data transmission, and applies optical fiber high-speed data transmission to electronic products such as mobile phones. The transmission bandwidth of the optical fiber wire 421 is larger than that of the copper wire or other metal medium. At present, the optical fiber bandwidth can reach 1000 Mbps, and in the future it can reach more than 10 Gbps. In addition, the transmission distance of the optical fiber is far, the time delay is low, the packet loss rate and the bit error rate are low, and the transmission data is stable and efficient. In addition, the optical fiber data transmission is non-resistance transmission, consumes less energy, and has high transmission speed. In addition, the optical fiber wire 421 is an insulator, and is less affected by electromagnetic interference and crosstalk. In addition, the optical fiber wire 421 is not easily damaged due to damp, and the better user experience is not affected.
