Abstract:
1. A bi-directional optical transmitting and receiving apparatus comprising: a package having a cavity and allowing a plurality of lead wires to pass therethrough; a platform mounted on the package such that the cavity is completely covered, and including a through hole formed above the cavity and having sloped surfaces; a reception unit mounted within the cavity and generating an electrical signal corresponding to input light made incident to the cavity through the through hole and outputting the generated electrical signal to at least one of the plurality of lead wires; a transmission unit mounted on the platform such that the transmission unit is placed in a region in which the through hole is not formed, and generating output light according to an electrical signal transmitted through at least one of the plurality of lead wires; and a wavelength division multiplexing (WDM) filter mounted on the platform such that the WDM filter is placed above the through hole to transfer the output light toward an optical fiber and the input light toward the through hole, wherein a portion of the plurality of lead wires is positioned within the cavity.
