摘要 A duplex optical communication module unit is disclosed, which comprises a ceramic substrate and first and second metal shells having respective transparent window members and hermetically bonded to the ceramic substrate so as to define a first and second space, respectively. A light-emitting element is assembled in the first space, and a light-emitting element and a circuit element for amplifying the photocurrent from the light-emitting element are assembled in the second space.
