Abstract

The invention provides a data transmission method, a data transmission device, a photoelectric conversion device and a photoelectric conversion system, wherein the method comprises the steps of: extracting data to be transmitted from a received common public radio interface CPRI frame; inserting the data to be transmitted into an Ethernet frame, wherein the period of the Ethernet frame and the period of the CPRI frame are same; and sending the Ethernet frame. The problem that CPRI frame data and Ethernet frame data cannot be synchronously transmitted in a related technology can be solved; andthus, synchronous transmission of the CPRI frame data and the Ethernet frame data is realized.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a data transmission method and device, and a photoelectric conversion device and system. Background technique [0002] As people's demand for data is increasing, and there are more and more applications in indoor scenarios, outdoor macro stations cannot solve indoor coverage problems well. In order to better improve the user experience of indoor scenes, an indoor distribution system was developed accordingly. The traditional macro radio remote unit (Radio Remote Unit, referred to as RRU) uses optical fiber to connect to the baseband processing unit (Building Baseband Unit, referred to as BBU) for communication, but in indoor coverage, the optical fiber resources are less, and the Ethernet cable There are many resources, in order to save resources to the greatest extent and better layout. Indoor coverage adopts remote radio frequency equipment based on network cable transmissi...
