[Prior Art] With the advancement of communication technology, the current communication method is not limited to the electric signal to realize the fiber-optic technology in recent years. Since the transmission rate of light in the domain towel is much higher than the rate of electron transfer in the wire, the fiber communication can greatly increase the rate of data transmission and increase the rate of downloading or uploading in the network. In the conventional two-way optical communication system, the system side and the user end each have a bidirectional optical subassemMy (BOSA), and the two bidirectional optical submodules are connected by an optical fiber. When the user wants to transmit the signal to the system end, the optical transceiver component in the two-way optical sub-module of the user end converts the electrical signal of the user end into an optical signal, and the optical signal is transmitted to the two-way optical sub-system through the optical fiber. Module. After receiving the optical signal, the optical transceiver component in the bidirectional optical sub-module of the system converts the optical § hole number into an electrical signal for processing by the system. Conversely, when the system side wants to transmit the signal to the user end, the optical transceiver component in the bidirectional optical sub-module of the system side converts the electrical signal of the system end into an optical signal, and the optical signal is transmitted to the user's two-way via the optical fiber. Light sub-module. After receiving the optical signal, the optical transceiver component in the two-way optical sub-module of the user end converts the optical signal into an electrical signal for the user to handle the bidirectional optical communication of the M406322 side. Since the development of optical transceivers has become a design of optical transceiver components, it has become an important issue for the system and the user to simplify the internal structure of the electronic components and to reduce the size of the internal components. [New content] This is to provide a kind of optical transceiver component, which can have a simplified structure and a smaller H and help to make the process easier and reduce the manufacturing cost. The creation of the creation - the actual _ proposed - a pure hair component, including a shell, - light detector, detector, a lighting unit, - power debt detector and - refracting single 兀. The outer casing has a through hole H that is disposed within the outer casing and is adapted to receive a receiving beam from outside the outer casing and entering through the (four) hole. The emitter is disposed within the housing and is adapted to emit a beam of light, wherein the portion of the emitted beam is adapted to pass outside the housing via the via. The sacred (7) configuration is set within the transmission path of the other part of the transmitted beam to monitor the light intensity of the emitted beam. The refraction unit is disposed on the power recliner: in the illumination unit and the work (4), the emission light weight is another, wherein the refraction unit has a refraction surface, and the refraction surface is adapted to steer another part of the beam to the power detection Device. In the optical transceiver component of the embodiment of the present invention, since the unit is used to steer another part of the emitted light beam and is directed to the power detector, the direction and position of the power detector can be more flexible, and the power side is摆 erect in an upright manner. In this way, the assembly process of the power detector will also help to reduce the size of the optical transceiver component 6322. To make the above-described features and advantages of the present invention more comprehensible, the following detailed description of the embodiments and the accompanying drawings are set forth below. [Configuration Mode] Fig. 1 is a schematic cross-sectional view showing an optical transceiver unit according to an embodiment of the present invention. Referring to FIG. 1, the optical transceiver component 10() of the present embodiment includes a housing 110, a photodetector 120, a light emitting unit 130, a power detector 14A, and a refraction unit 150. The outer casing 11 has a through hole 1U. In this embodiment, the housing 110 includes a base 112 and an upper cover 114, wherein the base 12 is, for example, a transistor profile head (transist〇r 〇utiine hea<jer, TO-header), and the upper cover ι14 is for example Transist〇r outline can (TO-can). In the present embodiment, the through hole in is located on the upper cover 114. The photodetector 120 is disposed within the housing 11A and is adapted to receive a received beam 52 from outside the housing 110 and entering through the via 111. In this embodiment, the photodetector 120 is disposed on the susceptor 112, and the photodetector 120 is, for example, a photodiode. Specifically, the photodetector 120 is adapted to receive the received light beam 52 ′ from an optical fiber 50 above the through hole in and convert the optical signal contained in the received light beam 52 into an electrical signal after detecting the received light beam 52 . . In this embodiment, the optical transceiver component 1 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 M406322 illumination unit 130 is disposed within the housing 110 and is adapted to emit an emission beam 132, wherein a first portion 1323 of the emission beam 132 is adapted to be transmitted out of the housing 110 via the via 111. The light emitting unit 13 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. In the present embodiment, the power detector 14 is, for example, a photodiode. The refraction unit 150 is disposed on the power detector 14A and is disposed on the transmission path of the second portion 132b of the emission beam 132 between the illumination unit 130 and the power detector 140. The refractive unit 15A has a refractive surface 152 adapted to divert the second portion 13 of the transmitted beam 132 to the power detector 140. In the present embodiment, the refractive surface 15 is, for example, a curved convex surface. In the optical transceiver component 1 of the present embodiment, since the μ element 150 is used to steer the second portion 132b of the emitted light beam 132 to the single detector 140, the direction of the power detector 14〇 is set. It is more flexible with the position, and is not limited to the power detector 14 being erected. As a result, it helps to simplify the assembly and wear of the power detector 14 and also contributes to reducing the overall size of the optical transceiver component 100. The illuminating unit 130 and the power detector 14 are disposed on the pedestal ι 2 in the present embodiment. The optical transceiver unit 1 further includes a carrying platform 17 〇 disposed in the housing no and has a carrying surface 172. The transmitter unit 1 and the power detector 140 are disposed on the carrying surface 172, and the carrier is disposed on the base 112. In addition, in this embodiment, the light-emitting unit 7 1VHU6322 is a side-emitting type laser diode, and the light-emitting layer 134 of the light-emitting unit 13A is substantially parallel to the light-absorbing layer 142 of the power detector 140. In other words, since the refraction unit 150 steers the second portion 132b of the emitted light beam 132, the power detector 140 can be horizontally affixed to the carrying surface 172 like the light emitting unit 13〇 without having to cause the power detector 14 to The vertical arrangement is such that the light layer 142 is placed perpendicular to the light emitting layer 134. In this way, the assembly process of the optical transceiver component 100 can be simplified, thereby reducing the cost. In addition, since the power detector 140 and the light emitting unit 130 are both flat on the carrying platform 17, the optical transceiver component 100 can be vertically attached to the power detector 14 without using another carrier. In addition to the process and cost reduction, the volume of the optical transceiver component 100 can also be reduced. In the present embodiment, the material of the refractive unit 150 is, for example, a transparent colloid. However, in other embodiments, the material of the refractive unit 15A may also be glass or other transparent material. In the present embodiment, the refraction unit 15 covers the power detector 140, and the refraction unit 15 has the function of a lens to refract the second portion 132b of the emitted beam 132 to the power detector 14A. In this embodiment, the optical transceiver component 100 further includes a wavelength division multiplexer (WDM) 180 disposed on the transmission path of the first portion 132a of the emission beam 132 between the light emitting unit 130 and the through hole 111. 'And disposed on the transmission path of the receiving beam 52 between the photodetector 120 and the through hole U1. The wavelength of the emitted light beam 132 is different from the pick-up beam μ' and the wavelength separating multiplexer 180 separates the transmission path of the first portion 132a of the emitted light beam 132 from the transmission path of the received light beam 52 depending on the wavelength. M406322 Specifically, the wavelength separating multiplexer 180 is, for example, a dichroic mirror. The dichroic mirror is adapted to allow the receiving beam 52 from the through hole ill to pass through to the photodetector 〇2〇, and The first portion 132a of the emitted light beam 132 from the light emitting unit 130 is reflected to the through hole ill. However, in other embodiments, the dichroic mirror may also reflect the received beam 52 to the photodetector 120' and pass the first portion 132a of the transmitted beam 132 to the via 111. In the present embodiment, the wavelength separating multiplexer 18 can be disposed on the susceptor 112 by a supporting unit 230. In this embodiment, the optical transceiver component 1 further includes a lens 丨9〇 disposed in the through hole 111 to converge the first portion 132a of the emitted light beam 132 in the optical fiber 50, and converge the received light beam 52 at the wavelength. Separating the multiplexer 180. In the present embodiment, the optical transceiver component 1 further includes a plurality of pins 210 electrically connected to the light emitting unit 130, the photodetector 120, and the power detector. In addition, these pins 2 can be electrically connected to the system side or the user end, wherein the system side or the user side is, for example, a computer system, a server, a router, or other network system. For example, the system end and the user end each may have an optical transceiver component 100, and the two optical transceiver components 1〇〇 are connected by an optical fiber 5〇. The light detector 120 can convert the optical signal contained in the received light beam 52 into an electrical signal after detecting the received light beam 52, and the electrical signal is transmitted to the system end connected to the optical transceiver component 1 through the lead pin 21〇. Or the user end, and complete the reception of the signal. Alternatively, the system or user terminal can transmit an electrical signal to the optical transceiver component 1 to which it is connected, for example, to cause the electrical signal to be transmitted from the pin 210 to the illumination unit 13A. The illumination unit 13 converts the telecommunications 9 M406322 into an optical signal contained in the transmitted beam 132, and the power detector i4〇 can instantly monitor the power of the transmitted beam 132 to ensure the correctness of the optical signal. In this way, the signal is transmitted. Therefore, the optical transceiver component 100 of the embodiment can achieve the function of two-way optical signal transmission and reception. In the present embodiment, the optical transceiver component 100 can be disposed in a housing 30 and one end of the optical fiber 50 can be fixed to the housing 30 by a holder 40. In this embodiment, the optical transceiver component 100 further includes a filter 22, disposed on the transmission path of the receiving beam 52 between the wavelength separating multiplexer 180 and the photodetector 120, and the filter 22〇 It is suitable for passing light having a wavelength of the received light beam 52 and blocking light having other wavelengths. In this way, it is ensured that the optical signal detected by the photodetector 120 is not interfered with by other stray light (for example, stray light in the environment). However, in other embodiments, the optical filter may be disposed on the filter. The transmission path of the receiving beam 52 between the optical fiber 5〇 and the wavelength separating multiplexer 18〇 and the transmission path of the first portion 132a of the emitted light beam 132, at which time the filter is adapted to have the wavelength of the receiving beam 52 and the emitted beam. Light of a wavelength of 132 passes and blocks light having other wavelengths. According to the gas τ', in the optical transceiver component of the embodiment of the present invention, since the refractive unit is used to steer the second portion of the emitted light beam and is directed to the power detection, the direction of the power detector is set. And the position can be more flexible ^ not limited to the material touch upright erect. In this way, it helps to simplify the assembly process of the power detector, and also helps to reduce the overall size of the optical transceiver.
