The application provides a method for measuring a dispersion coefficient of an optical fiber. A network device sends a first optical supervisory channel (OSC) measurement signal and a second OSC measurement signal, where wavelengths of the first OSC measurement signal and the second OSC measurement signal are different. The network device receives the returned first OSC measurement signal and second OSC measurement signal, where the first OSC measurement signal and the second OSC measurement signal are transmitted through a first optical fiber and a second optical fiber to return to the network device, and the first optical fiber and the second optical fiber are a to-be-tested optical fiber. The network device determines a delay difference between the received first OSC measurement signal and second OSC measurement signal. The network device determines a dispersion coefficient of the to-be-tested optical fiber based on the delay difference.

A dynamic random access memory (DRAM) refresh method in which a to-be-refreshed area in a refresh block is specified in a refresh instruction is provided to refresh a specified location of a DRAM storage array. A memory controller sends a refresh instruction to a DRAM refresh apparatus. The refresh instruction includes an identifier of a to-be-refreshed block and refresh information indicating a to-be-refreshed area. The DRAM refresh apparatus generates addresses of to-be-refreshed bank rows in the to-be-refreshed block according to the identifier and the refresh information, and refresh locations corresponding to the addresses of the bank rows in the to-be-refreshed block. Therefore, a DRAM refresh time is shortened, refresh power consumption is reduced, a refresh operation is more flexible, and system resource consumption is reduced while data integrity is ensured.

Circuit and array circuit for implementing shift operation

A cabinet server and a data center where the cabinet server includes multiple function node layers vertically arranged to form a server core and multiple intra-cabinet antennas vertically arranged and disposed at one side of the server core, an intra-cabinet antenna is wirelessly connected to adjacent intra-cabinet antennas. A transmission path is formed of the vertically arranged intra-cabinet antennas when a radio signal is transmitted within the cabinet server. Since the intra-cabinet antennas are disposed at the side of the server core, electromagnetic radiation generated by the radio signal in a transmission process has a relatively small effect on the function nodes, thereby reducing the effect of the electromagnetic radiation on various electronic devices in the function nodes, improving service lives of the electronic devices, and improving transmission quality of the radio signal.
