Description
本創作係有關於一種光收發裝置，尤指一種體積較小且結構簡單之光收發裝置。The present invention relates to an optical transceiver device, and more particularly to an optical transceiver device that is small in size and simple in structure.
隨著網路技術的快速發展，光纖通訊技術因具有傳輸速度快，傳輸距離長，可抗電磁干擾，以及安全性高等諸多優點，業已成為現代主要發展的通訊技術。With the rapid development of network technology, optical fiber communication technology has become a major communication technology in modern times due to its advantages of fast transmission speed, long transmission distance, resistance to electromagnetic interference, and high security.
習知光收發裝置主要係由光電轉換器、光路切換開關、以及光收發組件所構成。The conventional optical transceiver device is mainly composed of a photoelectric converter, an optical path switching switch, and an optical transceiver assembly.
就該光電轉換器而言，其主要負責光訊號與電訊號之相互轉換處理，習知光電轉換器大都是以零部件的形式獨立組設於光收發裝置中，由於單個光電轉換器所提供的訊號傳遞通道數量有限，因此，當光收發裝置同時連接多個光纖網路設備時，即需組設多個光電轉換器於其中，從而導致光電轉換模塊的大型化，造成習知光收發裝置的體積較大。In the case of the photoelectric converter, it is mainly responsible for the mutual conversion processing of the optical signal and the electrical signal. Most of the conventional photoelectric converters are independently assembled in the optical transceiver device in the form of components, due to the provision of a single photoelectric converter. The number of signal transmission channels is limited. Therefore, when the optical transceiver device is connected to a plurality of optical network devices at the same time, a plurality of photoelectric converters are required to be disposed therein, thereby causing an increase in the size of the photoelectric conversion module, resulting in a smaller volume of the conventional optical transceiver device. Big.
此外，光收發裝置中的光路切換開關與光收發組件間的光訊號傳遞是藉由光纖纜線而達成，由於光訊號在光纖纜線中是利用光的折射以及全反射而傳遞，故用於傳遞光訊號的光纖纜線就必須有一定程度的彎曲半徑(Bending Radius：依EAI/TIA 568規範，多模光纜佈線彎曲半徑不得低於25mm)，以使得光訊號在不衰減的情形下持續於光纖纜線中傳遞。如此，光收發裝置的內部就需要預留空間容納光纖纜線導致體積無法被縮小，而無法達成光收發裝置小型化的發展趨勢。In addition, the optical signal transmission between the optical path switching switch and the optical transceiver component in the optical transceiver device is achieved by using a fiber optic cable. Since the optical signal is transmitted by optical refraction and total reflection in the optical fiber cable, it is used for The fiber optic cable that transmits the optical signal must have a certain degree of bending radius (Bending Radius: according to EAI/TIA 568 specification, the bending radius of the multimode fiber cable must not be less than 25mm), so that the optical signal continues without attenuation. Pass in the fiber optic cable. In this way, the inside of the optical transceiver device needs to reserve space for accommodating the optical fiber cable, so that the volume cannot be reduced, and the development trend of miniaturization of the optical transceiver device cannot be achieved.

請參閱圖5A，當驅動單元1315控制光學元件1314移離光路空間1313時，光路切換模組13之光開關131係運行一般模式（Normal Mode），於此運行模式下，光輸入端1311的輸入光線能夠依序通過光路空間133、光導波器12傳遞至光電轉換模組11；光電轉換模組11所提供的光線能夠依序通過光導波器12、光路空間133傳遞到光輸出端1312。Referring to FIG. 5A, when the driving unit 1315 controls the optical component 1314 to move away from the optical path space 1313, the optical switch 131 of the optical path switching module 13 operates in a normal mode. In this operating mode, the input of the optical input terminal 1311 is performed. The light can be transmitted to the photoelectric conversion module 11 through the optical path space 133 and the optical waveguide 12 in sequence; the light provided by the photoelectric conversion module 11 can be sequentially transmitted to the optical output terminal 1312 through the optical waveguide 12 and the optical path space 133.
請繼續參閱圖5B，當驅動單元1315控制光學元件1314移入光路空間1313時，係使光路切換模組13運行旁路模式(Bypass Mode)，於此運行模式下，由光輸入端1311所輸入載有光訊號之光線在經過光學元件1314的全反射後，光線行進的通道會由光輸入端1311之光路通道切換到光輸出端1312之光路通道，如此光線可在不經由在線設備4的情況下，直接由光輸出端1312輸出。亦即，可在不經由在線設備4的情況下，令第一光纖網路設備2與第二光纖網路設備3能通過光路切換模組13相互傳遞光訊號，從而實現第一光纖網路設備2與第二光纖網路設備3之間無間斷的光訊號傳遞。Referring to FIG. 5B, when the driving unit 1315 controls the optical element 1314 to move into the optical path space 1313, the optical path switching module 13 is caused to operate in a bypass mode.
