1. An information transmission method, which is applied to architecture of an optical network, the architecture of the optical network comprising a transmission device and a reception device both being provided with optical communications modules, the information transmission method comprising:
obtaining, by the transmission device, Operation, Administration and Maintenance (OAM) information from the architecture of the optical network;
encapsulating, by the transmission device, the obtained OAM information to form an OAM frame, the OAM frame comprising N data frames each having a frame length of L, N varying along with a volume of the OAM information, L being a constant value regardless of the volume of the OAM information; and
transmitting, by the transmission device, the OAM frame to the reception device,
wherein each of the N data frames comprises a variable first field for carrying variable OAM information, and a variable fourth field for padding a vacant part of the data frame, wherein the variable fourth field is not checked during checking operation;
wherein the data frame further comprises modular ID, which is used to identify a management channel corresponding to the data frame.
