OPTICAL COMMUNICATION DEVICE AND OPTICAL SIGNAL PROCESSING METHOD

This application discloses an optical communication device and an optical signal processing method. The optical communication device includes two optical transmitting devices and two optical receiving devices, and further includes an optical path component and an optical fiber adapter. A first converging lens packaged in the optical transmitting device converges a light beam emitted by a light source, and then provides a converged light beam for the optical path component. A second converging lens packaged in the optical receiving device converges a light beam from the optical path component, and then provides a converged light beam for a photoelectric detection element. Because the optical transmitting device and the optical receiving device can converge light beams, there is no need to dispose a relatively large quantity of lenses in the optical path component to establish a complex optical path to implement optical transmission, thereby reducing material costs of the optical communication device. In addition, an optical path is simplified, so that complexity of the optical path is reduced, and process costs are reduced. In addition, a quantity of used lenses is reduced, so that a quantity of optical coupling dimensions between mechanical parts in the device is correspondingly reduced, thereby improving production efficiency of a Combo PON product.
