In the present embodiment, the photodetector 120 is disposed on the susceptor 112, and the photodetector 120 is, for example, a photodiode. The photodetector 120 is adapted to receive the receiving beam 52 from an optical fiber 50 above the through hole 111, and convert the optical signal contained in the receiving beam 52 into an electrical signal after detecting the receiving beam 52. In an embodiment, the optical transceiver component 100 M406321 further includes a transimpedance amplifier 160 disposed in the housing 110 and electrically connected to the photodetector 120. The transimpedance amplifier 160 can be disposed on the pedestal 112 and is adapted to amplify the electrical signal transmitted by the photodetector 52 to facilitate interpretation. The illumination unit 130 is disposed within the housing 110 and is adapted to emit an emission beam 132' wherein a first portion 132a of the emission beam 132 is adapted to be transmitted out of the housing 110 via the through hole 111. The light emitting unit 130 is, for example, a laser diode (LD). The power detector 140 is disposed in the housing 110 and is located on a transmission path of a second portion 132b of the emitted light beam 132 to monitor the light intensity of the emitted light beam 132. In this embodiment, the power sensor 140 is, for example, a photodiode. The light transfer unit 150 is disposed on the power detector 140 and covers a first end 136a of the second portion 132b of the light emitting unit 130 that emits the light beam 132, and exposes the first portion of the light emitting unit 132 that emits the emitted light beam 132. One of the second ends 136b of 132a. The second portion 132b of the emitted light beam 132 from the illumination unit 130 is passed to the power detector 140 in the light transfer unit 150. The light transmitting unit 150 has a reflective curved surface 152 adapted to reflect the second portion 132b of the emitted light beam 132 from the light emitting unit 130 to the power detector 14A. In the present embodiment, the reflective curved surface 15 2 is, for example, a "curved convex surface. In the optical transceiver component 100 of the present embodiment, since the light transmitting unit 150 is employed to cause the second portion 132b of the emission beam 32 to be reflected by the reflective curved surface 152 to the power controller 14', the direction of the power detector (10) is set.
