1. A butterfly-type packaged optical transceiver comprising:
a box-shaped housing having a through hole;
a cover plate coupled with the box-shaped housing, and forming an internal space with the box-shaped housing;
an optical receiving module disposed in the internal space, and comprising a plurality of optical detectors;
an optical emitting module disposed in the internal space, and comprising a plurality of laser diodes;
a prism filter module disposed in the internal space and between the optical detectors and the laser diodes, and extending in an axis, wherein the prism filter module comprising a plurality of prism filters arranged along the axis, and each of the prism filters is between one of the optical detectors and one of the laser diodes in a direction perpendicular to the axis, wherein centers of the prism filter module and the through hole define an axis;
an optical fiber connector connected to the through hole; and
a plurality of electrical connection elements respectively penetrating both side surfaces and electrically connected to the optical receiving module and the optical emitting module, wherein the side surfaces are adjoining a surface of the box-shaped housing contacting with the optical fiber connector,
wherein a first optical signal comprising a plurality of sub-optical signals is transmitted to the prism filter module via the optical fiber connector and the through hole, and each of prism filters reflects one of the first sub-optical signal to one of the optical detectors, and
wherein each of the laser diodes emits a second sub-optical signal to one of the prism filters, and the optical emitting module emits a second optical signal comprising the second sub-optical signals to an exterior of the box-shaped housing via the prism filter module, the through hole and the optical fiber connector.
