The invention relates to a multi-Ethernet photoelectric conversion device and a method for receiving and transmitting fiber data, by judging the size of parallel data bit m and multi-path Ethernet data total bit 5*n processed by serial parallel conversion of an optical transceiver module, if the parallel data bit m is greater than or equal to 5*n, n-path Ethernet data frames are directly mapped to a fixed virtual circuit in turn so that multi-path Ethernet data can be transmitted in the same optical fiber and are physically isolated with each other, so the method has the advantages of little time delay and optical channel resource conservation; and if the parallel data bit m is less than 5*n, frame positioning is achieved through frame positioning bytes, the n-path Ethernet data frames are mapped to a corresponding virtual circuit so that the multi-path Ethernet data can be transmitted in the same optical fiber and are physically isolated with each other.

The invention discloses a photoelectric converter based on an 802.3ah management protocol, comprising a conversion unit, an electric port unit and an optical port unit. The conversion unit comprises an Ethernet data caching module, an OAM (Operations, Administration and Maintenance) data processing module, an OAM control module, an analyzing module and a multiplexing module, wherein the OAM data processing module is used for transmitting OAM management frame content to be transmitted to the OAM control module and receiving far-end information transmitted by the OAM control module; the OAM control module is used for packaging the content transmitted by the OAM data processing module into a corresponding 802.3ah OAM management frame to be transmitting to the multiplexing module, receiving the 802.3ah OAM management frame analyzed by the analyzing module and then transmitting the unpackaged frame content to the OAM data processing module; and the multiplexing module is connected with theoptical ...
