Claim:
1. A bi-directional optical transceiver module, comprising: a holder into which an optical fiber for outputting a first optical signal is inserted, the first optical signal having an optical axis; an optical transmitter configured to output a second optical signal to the optical fiber; an optical receiver configured to receive the first optical signal; a first optical filter configured to reflect the first optical signal, and allow the second optical signal to pass through; a reflector configured to reflect the first optical signal reflected by the first optical filter to the optical receiver side; and a second optical filter disposed between the reflector and the optical receiver, wherein a first inclined angle between the first optical filter and a first axis is smaller than a second inclined angle between the reflector and a second axis, wherein the first axis and the second axis are parallel to each other and are perpendicular to the optical axis, wherein a first light emitted from the holder and incident to the first optical filter does not cross a second light which is reflected by the reflector and is incident to the optical receiver, wherein the holder comprises a first inclined surface in which the first optical filter is disposed, a second inclined surface in which the reflector is disposed, and a step part in which the second optical filter is disposed.
