Original Abstract Submitted
Embodiments of this application disclose a baseband unit (BBU) and an access network device. The BBU includes M lasers, M switches (SWs), M photodetectors (PDs), an arrayed waveguide grating (AWG), M transmit ports, and M receive ports, where M is an integer greater than or equal to 2. An ilaser is coupled to an input end of an iSW, an upper output end of the iSW is coupled to an itransmit port, and the AWG is separately coupled to lower output ends of the M switches SWs, the M PDs, and the M receive ports, where i=1, 2, . . . , or M. When a networking mode used by the BBU needs to be changed, an optical module or a component in the BBU does not need to be replaced, so that applicability, universality, and flexibility of the BBU can be improved.
