The circuit substrate assembly 51 is configured to transmit and receive electrical signals.

該電路基板組合51具有一塊電路板(PCB)511、一塊硬質陶瓷板(Ceramic submount)512，及至少一塊驅動積體電路(Driver IC)513，該電路板511用以收發電訊號並包括一穿孔501，及四個分別供該等第二定位柱332穿過的穿設孔502，該硬質陶瓷板512的熱傳導率大於該電路板511，並連接於該電路板511的一底面503，且具有複數個對應該等穿設孔502、第二定位柱332的第二定位孔504，該至少一塊驅動積體電路513位於該穿孔501且接觸該硬質陶瓷板512地設置於該硬質陶瓷板512上。在本例中以四個穿設孔502、四個第二定位孔504、二塊驅動積體電路513作說明；該座板33藉該四支第二定位柱332穿過該電路板511的四個穿設孔502並對應抵靠限位於該硬質陶瓷板512的四個第二定位孔504，使該座殼31與該電路基板組合51直接且精確地定位結合。The circuit board assembly 51 has a circuit board (PCB) 511, a ceramic submount 512, and at least one driver IC (513) for transmitting and receiving electrical signals and including a perforation. 501, and four through holes 502 for the second positioning posts 332 to pass through, the hard ceramic plate 512 has a thermal conductivity greater than the circuit board 511, and is connected to a bottom surface 503 of the circuit board 511, and has The plurality of second positioning holes 504 corresponding to the holes 502 and the second positioning posts 332 are disposed on the hard ceramic plate 512. . In this example, four through holes 502, four second positioning holes 504, and two driving integrated circuits 513 are illustrated; the seat plate 33 is passed through the circuit board 511 by the four second positioning posts 332. The four through holes 502 are correspondingly disposed to the four second positioning holes 504 of the hard ceramic plate 512, so that the seat shell 31 and the circuit substrate assembly 51 are directly and accurately positioned and coupled.
該光元件組合52位於該穿孔501且接觸該硬質陶瓷板512地設置於該硬質陶瓷板上512，包括至少一個垂直共振腔面射型雷射(VCSEL)，或至少一個光電二極體(PD)，該至少一塊驅動積體電路513、該至少一個垂直共振腔面射型雷射(VCSEL)，或至少一個光電二極體與該電路板511藉由例如金線打線(wire bonding)方式與該電路板511電連接。在本例中，以四個分別發出850nm、880nm、910nm、940nm的雷射光的垂直共振腔面射型雷射作說明。The light element assembly 52 is disposed on the hard ceramic plate 512 and contacts the hard ceramic plate 512, and includes at least one vertical cavity surface-emitting laser (VCSEL), or at least one photodiode (PD). The at least one driving integrated circuit 513, the at least one vertical cavity surface-emitting laser (VCSEL), or the at least one photodiode and the circuit board 511 are connected by, for example, a gold wire bonding method. The circuit board 511 is electrically connected. In this example, a vertical cavity surface-emitting laser that emits laser light of 850 nm, 880 nm, 910 nm, and 940 nm, respectively, will be described.
電訊號經由該電路板511傳送，該驅動積體電路513對應該電訊號驅動該等垂直共振腔面射型雷射作動發光，該等垂直共振腔面射型雷射作動發出的雷射光經該透鏡組合413聚光後進入該分波空間301，並分別對應該等濾波反射組件41的反射膜411、濾波器412反射、濾波後由該光纖100向外以光訊號方式傳輸。特別地，該等垂直共振腔面射型雷射作動發出的雷射光能同時以單一通道(即該光纖100)載入多個波長的光訊號，而有效提升傳輸速率。The electrical signal is transmitted through the circuit board 511, and the driving integrated circuit 513 drives the vertical cavity surface-emitting lasers corresponding to the electric signals, and the laser light emitted by the vertical cavity surface-emitting lasers passes through the laser light. The lens assembly 413 is condensed and enters the splitting space 301, and is respectively reflected and filtered by the reflective film 411 and the filter 412 of the filter unit 41, and then transmitted by the optical fiber 100 to the optical signal. In particular, the laser light emitted by the vertical cavity surface-emitting laser can simultaneously load optical signals of multiple wavelengths in a single channel (ie, the optical fiber 100), thereby effectively increasing the transmission rate.
同時，由於該驅動積體電路513與該光元件組合52是直接接觸該硬質陶瓷板512地設置於該硬質陶瓷板512上，所以作動時產生的廢熱可以直接自該硬質陶瓷板512排離自身，從而以熱電分離的路徑穩定維持光訊號與電訊號的傳輸。At the same time, since the driving integrated circuit 513 and the optical element combination 52 are directly disposed on the hard ceramic plate 512 in contact with the hard ceramic plate 512, the waste heat generated during the operation can be directly discharged from the hard ceramic plate 512. Therefore, the transmission of the optical signal and the electrical signal is stably maintained by the path of the thermoelectric separation.
再者，該座殼31以該四支第一定位柱313抵靠該座板33的第一定位孔331、該座板33以四支第二定位柱332穿過該電路板511的穿設孔502抵靠於該硬質陶瓷板512的四個第二定位孔504，而使該座殼31、座板33、電路基板組合51簡易且直接地定位組合。Furthermore, the housing 31 is disposed with the four first positioning posts 313 against the first positioning holes 331 of the seat plate 33, and the seat plate 33 is inserted through the circuit board 511 by the four second positioning posts 332. The hole 502 abuts against the four second positioning holes 504 of the hard ceramic plate 512, so that the seat shell 31, the seat plate 33, and the circuit board assembly 51 are simply and directly positioned and combined.
要再說明的是，該光元件組合52包括至少一個光電二極體時，光訊號經過該光纖100傳入該分波空間301，再對應該等濾波反射組件41的反射膜411、濾波器412反射、濾波後，由該透鏡組合413聚光於該等光電二極體，從而將光訊號經由該驅動積體電路513轉換成電訊號自該電路板511傳輸。It is to be noted that when the optical component combination 52 includes at least one photodiode, the optical signal is transmitted to the splitting space 301 through the optical fiber 100, and then the reflective film 411 and the filter 412 of the filter unit 41 are correspondingly filtered. After being reflected and filtered, the lens assembly 413 is condensed on the photodiodes, and the optical signals are converted into electrical signals from the circuit board 511 via the driving integrated circuit 513.
參閱圖4，本發明分波多工光收發器的另一個實施例，是與上例相似，不同處僅在於該座殼31’和該座板33’。該座殼31’的四支第一定位柱313’長度較長，該座板33’具有四個定位穿設孔333，該座殼31’的該等第一定位柱311’穿設過該座板33’的該等定位穿設孔333與該電路板511的四個穿設孔502而對應抵靠限位於該硬質陶瓷板512的該等第二定位孔504，而使該座殼31’、座板33’、電路基板組合51簡易且直接地定位組合。Referring to Fig. 4, another embodiment of the split multiplex optical transceiver of the present invention is similar to the above example except that the housing 31' and the seat plate 33' are different. The four first positioning posts 313' of the housing 31' have a longer length, and the seat plate 33' has four positioning through holes 333 through which the first positioning posts 311' of the housing 31' are The positioning through holes 333 of the seat plate 33 ′ and the four through holes 502 of the circuit board 511 are correspondingly abutted against the second positioning holes 504 of the hard ceramic plate 512 , so that the housing 31 is The 'seat plate 33' and the circuit board assembly 51 are simple and directly positioned and combined.
