Abstract[English]
The present application relates to the technical field of optical communication devices. Disclosed is an optical module. The optical module comprises a light source assembly and an optical amplification assembly, wherein the optical amplification assembly is optically connected to the light source assembly, and the optical amplification assembly is used for performing optical amplification on an optical signal which is output by the light source assembly, so that the optical module has a relatively high output power. Moreover, in the present application, a pump source device of the optical amplification assembly is arranged on a bearing surface on one side of a main circuit board, and a variable optical attenuator is arranged on a bearing surface on the other side of the main circuit board. That is, by rationally arranging functional devices of the optical amplification assembly, the size of the optical module can meet protocol requirements, and the optical module can accommodate the added optical amplification assembly, so that the optical module has a high output power.[French]
