Abstract: 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 ith laser is coupled to an input end of an ith SW, an upper output end of the ith SW is coupled to an ith transmit 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.

Abstract: A computer system includes a first computing node and a second computing node. The first computing node includes a first device and a first memory. The second computing node includes a second device and a second memory. The first memory includes a first memory space. The second memory includes a second memory space. The first device obtains a cross-node read instruction. The cross-node read instruction includes a virtual address of the second memory space and a size of first data. The first device determines an identifier (ID) of the second computing node based on the virtual address of the second memory space and a first correspondence, to obtain a first network transmission packet, and sends the packet to the second device. The second device receives the packet, reads the first data from the second memory space, and sends the first data to the first device.

Abstract: A frequency regulation method and apparatus is applied to an insulation impedance detection apparatus in a direct current power system, and relates to the field of security monitoring technologies of a direct current electrical system. The method includes: collecting sampling voltages at a sampling point for at least three time points; determining a voltage frequency regulation manner based on the sampling voltages, obtained through sampling, at the at least three time points; and then regulating a voltage frequency of a power supply according to the determined voltage frequency regulation manner. The voltage frequency of the power supply can be regulated based on the at least three sampling voltages obtained through sampling. Therefore, the insulation impedance detection apparatus reduces insulation impedance detection duration while ensuring accuracy of measured insulation impedance.

Abstract: An electronic device includes a first transmission circuit and an anti-interference circuit. The first transmission circuit includes a first receive end, a first transmit end, and a first conversion module. The first conversion module is configured to convert a first-type signal in a signal received by the first receive end into a second-type signal to be sent by the first transmit end. The anti-interference circuit is configured to cancel the second-type signal in the signal received by the first receive end. The cancelled second-type signal is sent by the first transmit end and then received by the first receive end.
