Abstract: Embodiments of the present invention provide a protocol conversion method and apparatus. The method includes: implementing frequency synchronization and time synchronization with a baseband unit (BBU) using an Ethernet protocol; obtaining frequency synchronization information and time synchronization information in a first format from an Ethernet interface; converting the frequency synchronization information and the time synchronization information in the first format into frequency synchronization information and time synchronization information that are in a second format, where the second format is a common public radio interface CPRI protocol format; and sending the frequency synchronization information and time synchronization information in the second format to a remote radio unit (RRU) using a CPRI interface, where the RRU supports a CPRI protocol.

Abstract: A sleeve assembly is disclosed, including: a sealing rubber plug, a sleeve body, a locking nuts, and a fastening wrench. The sealing rubber plug includes a rubber plug body, a through hole is disposed in the rubber plug body, and a cable that needs to be inserted into a device can be inserted into the through hole. The sleeve body has two opposite ends, a sealing ring is disposed on one end of the sleeve body, and a hollow bolt head is disposed on the other end of the sleeve body. The sleeve assembly can implement a cable protection function when the device requires high-density cable routing. Surface space of the device is not occupied during cable mounting, and mounting efficiency is high.
