Abstract
An optical communication module is provided with a platform to provide an accurate axial alignment with optical transceiving subassemblies. In the optical communication module, axes of the optical transceiving sub-assemblies are aligned by virtue of previously established axial alignment of the platform, and the platform is fixed to a main body by inserting an insertion jaw of a cover into an insertion groove formed on an upper surface of the platform. After the optical transceiving subassemblies are inserted into the platform having the axial alignment required for a system, a bonding agent is filled into spaces defined in the platform, thereby preventing the axes from deviated by an external force. The optical communication module allows for easier and more accurate guidance of a connection between the optical transceiving sub-assemblies and the optical connector, thereby minimizing the optical loss, and preventing the patterns on the printed circuit board from being damaged due to the insertion and disconnection of the optical connector.
