One example optical transceiver includes an optical interface, an optical receiver, and a polarization-maintaining optical waveguide, where the optical receiver includes a mixer, an optical-to-electrical converter, an analog-to-digital converter, and a digital signal processor. The optical interface is configured to receive first local oscillator light from a laser outside the optical transceiver; the mixer is configured to receive the local oscillator light and receive signal light modulated on laser light; the polarization-maintaining optical waveguide is configured to connect the optical interface and the optical receiver, where a polarization state of the local oscillator light remains unchanged when being transmitted in the polarization-maintaining optical waveguide; the optical-to-electrical converter and an analog-to-digital converter are configured to perform optical-to-electrical conversion and analog-to-digital conversion on the mixed light to obtain a digital electrical signal; and the digital signal processor is configured to process the digital electrical signal to obtain data.

A hybrid power driving system includes an engine including a crankshaft; and a dual clutch transmission system coupled to the crankshaft. The dual clutch transmission system includes a first clutch, a second clutch, and a transmission. Both the first and second clutches are connected with the crankshaft. The transmission includes a first input shaft connected with the first clutch, a second input shaft connected with the second clutch, shifting gear sets, where each shifting gear set includes at least a stationary gear and a free gear; and an output shaft having one end coupled with a differential. The other end of the output shaft is connected with a driving electric motor. The driving electric motor drives the output shaft directly.
