Abstract
A bi-directional optical module that provides an Rx unit and a Tx unit, where optical axes are perpendicular to each other, is disclosed. The optical module provides a housing that installs a WDM filter therein and assembles the coupling unit in a surface through the front alignment unit, the Tx unit in another surface opposite to the former surface, and the Rx unit in still another surface connecting the former two surfaces through the rear alignment unit. The axes of the Tx unit and the coupling unit are in parallel to each other, but the axis of the Rx unit is in perpendicular to the former two axes. The Rx unit installs a photodiode (PD) with an optically sensitive surface leveled with the surface of the rear alignment unit to which the Rx unit is attached.
