Abstract: A camera substrate assembly, a camera apparatus, and a terminal device, where the camera substrate assembly includes a rigid support plate and a printed circuit board laminated, where at least two mounting holes for accommodating camera chips are disposed on the printed circuit board, the rigid support plate has mounting surfaces facing the mounting holes respectively and are configured to support the camera chips, strength of the rigid support plate is greater than strength of the printed circuit board, and flatness of the mounting surfaces is less than a specified threshold. The mounting holes disposed on the printed circuit board and the mounting surfaces disposed on the rigid support plate are used to support cameras. This avoids impact of warpage on camera mounting when the printed circuit board and a flexible circuit board are laminated, and improves flatness after camera mounting.

Abstract: A method, an apparatus, and a communication node for suppressing output noises of peripheral component interconnect express (PCIe) devices in optical fiber communication is provided. The communication node includes a PCIe chip and a detection and control circuit connected to a transmitting end of the PCIe chip. The PCIe chip transmits an electrical signal by a transmitter of a first lane. The detection and control circuit detects a differential-mode voltage of the electrical signal. If the differential-mode voltage is lower than a first threshold, the detection and control circuit controls an optical module connected to the PCIe chip not to transmit an optical signal through the first lane of the optical module. When a PCIe system includes the communication node, output noises of the transmitter is suppressed, and a normal optical fiber communication link is ensured.

Abstract: A storage system and a method for processing a data operation request are disclosed. The method is applied to a storage system that has a write once read many (WORM) function. In the method, after the storage system receives a data operation request, which is used to change data stored in the storage system, sent by an application server, the storage system acquires a time difference between a real-time clock (RTC) and a reference clock, wherein the RTC is configured to provide system time for the storage system, and the reference clock cannot be modified when the system is running. Then, the storage system determines whether the time difference is greater than an accumulated time precision error of the reference clock, and refuses to execute the data operation request when the time difference is greater than the accumulated time precision error.
