A data transmission method, device and optical module

Abstract

The present application provides a data sending method, device and optical module, by establishing a data retransmission identification bit used to start the data retransmission function inside the optical module, wherein, when the data retransmission identification position is the third preset During the value period, if the data stored in the preset data storage space is sent out through the low-frequency information channel, and the response message that the data has been received returned by the receiving end is not received within the preset time interval, then after the data is sent On the premise that the number of sending times does not exceed the preset number of times threshold, the data is sent out again through the low-frequency information channel. In this way, the low-frequency message channel is used to transmit data to the remote system to realize the remote control of the remote optical module and its access to the host computer. The burden of implementing this mechanism by the host computer can also effectively improve the efficiency of the overall system when using the message channel to transmit data.

Description

technical field [0001] The present application relates to the technical field of optical communication, and in particular to a data sending method, device and optical module. Background technique [0002] In the access network communication system, an optical connection is established between the optical line terminal and the optical network unit to realize data communication. Specifically, the optical line terminal has a first optical module, and the optical network unit has a second optical module, and an optical connection is established between the first optical module and the second optical module; the optical line terminal communicates with the second optical module through the first optical module The module sends optical signals to realize that the optical line terminal sends data to the optical network unit; the optical line terminal receives the optical signal from the second optical module through the first optical module, and realizes that the optical line termin...

Problems solved by technology

In the physical network of the access network, the optical line terminal and / or the optical network unit are often located in an environment that is not convenient for manual operation, such as mountains, forests or even water bodies. Operating the host computer or using the host computer to control the optical module in these environments is difficult. become very difficult
