Abstract
A receiver optical module to facilitate the assembling is disclosed. The receiver optical module includes an intermediate assembly including the optical de-multiplexer and the optical reflector each mounted on the upper base, and the lens and the PD mounted on the sub-mount. The latter assembly is mounted on the bottom of the housing; while, the former assembly is also mounted on the bottom through the lower base. The upper base is apart from the bottom and extends in parallel to the bottom to form a surplus space where the amplifying circuit is mounted.
