[0037] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0038] Currently, the OTDRs used in the market are monitoring modules independent of the 25G BiDi optical module. These modules are not only large in size and consume a lot of power, occupying room space and affecting the room's communication capacity, but also have independent software, making system operation complex. To address these technical issues, this application provides an optical transceiver component that is suitable for single-fiber bidirectional optical fiber transmission systems and optimizes the structural layout, reducing structural volume.

[0039] Specifically, this application provides an optical transceiver assembly, including a base 1 with a first end and a second end arranged opposite to each other along its own axis, and an optical transmission channel connecting the first end and the second end. The base 1 has a first optical transmitting port 11, a first optical receiving port 12, a second optical transmitting port 13, a second optical receiving port 14, and an optical fiber connection port 15 arranged sequentially from the first end to the second end. A first optical transmitter 21 is encapsulated in the first optical transmitting port 11 and located at the first end of the base 1, and is used to generate a first wavelength optical signal. A first optical receiver 22 is encapsulated in the first optical receiving port 12 and is used to receive a second wavelength optical signal. A second optical transmitter 23 is encapsulated in the second optical transmitting port 13 and is used to generate a third wavelength optical signal. A second optical receiver 24 is encapsulated in the second optical receiving port 14 and is used to receive a fourth wavelength optical signal. An adapter 25 is encapsulated in the optical fiber connection port 15 and located at the second end of the base 1, and is used to output optical fiber signals or input light source signals.

[0040] This application embodiment includes an adapter 25, a base 1, and an optical transmitter and an optical receiver installed at the end and below the base 1, wherein the optical transmitter and the optical receiver are respectively installed on adjacent surfaces of the base 1 and adopt a staggered layout design on the same side.

[0041] In the embodiments of this application, the optical transceiver component provided in this application is implemented in the following manner: both the first wavelength optical signal and the third wavelength optical signal can be optical signals with wavelengths exceeding 2000nm. The first wavelength optical signal can be converted into an optical fiber signal and a second wavelength optical signal respectively by the blocking and filtering of the internal filter. The part converted into an optical fiber signal is output by the adapter 25, and the part converted into a second wavelength optical signal is received by the first optical receiver 22. Similarly, the third wavelength optical signal is converted into an optical fiber signal by the blocking and filtering of the internal filter and is output by the adapter 25. The external light source signal is converted into a fourth wavelength optical signal after being blocked and filtered by the adapter 25 and the internal filter and is received by the second optical receiver 24.

[0042] Furthermore, the optical transmitting port provided in this application embodiment is a PD or LD transmitting port, which can generate a collimated beam. In the optical transmitting component provided in this application embodiment, applied to an OTDR (Optical Time Domain Reflectometer) fiber optic network monitoring system, it can be embedded inside the OTDR, thus providing a highly integrated OTDR embedded optical transceiver component structure. By miniaturizing and embedding the OTDR optical components into a 25G BiDi BOSA, a 25G Quad-OSA (QOSA) product integrating OTDR functionality is created.

[0043] According to the embodiments of this application, the optical transceiver component integrates optical transceiver components suitable for single-fiber bidirectional optical fiber transmission systems by transmitting and receiving optical signals of different wavelengths, so as to provide an integrated optical transceiver component that better meets the needs of the optical communication market. Furthermore, the optical transceiver component provided in this application is installed in an embedded manner, which optimizes the structural layout, reduces the structural volume, and makes the optical transceiver component more practical and convenient.

[0044] In an optional example, the optical fiber signal includes a first optical fiber signal. A first filter 31 and a second filter 32 are disposed between the first optical transmitter 21 and the adapter 25. The first wavelength optical signal is filtered by the first filter 31 and the second filter 32 and converted into a first optical fiber signal, which is then output by the adapter 25.

[0045] For example, as described above, the light beam exceeding 2000nm emitted by the first optical transmitter 21 is filtered by the first filter 31, and the wavelength light of 1310-1379nm that is retained is filtered again by the second filter 32 and output through the adapter 25 and optical fiber.

[0046] Furthermore, a third filter 33 is disposed below the first filter 31. The first wavelength optical signal is filtered by the first filter 31 and the third filter 33 and converted into a second wavelength optical signal, which is received by the first optical receiver 22.

[0047] For example, the 1260-1285nm wavelength light filtered out by the first filter 31 will pass through the third filter 33 and finally be received by the first optical receiver 22.

[0048] It should be noted that in this application, the first light transmitter 21 and the adapter 25 are aligned, and the first filter 31 and the second filter 32 are both arranged on the straight beam path of the first light transmitter 21 and aligned to facilitate collimated light transmission. The first filter 31 and the third filter 33 are located directly above the first light receiver 22. After being filtered and refracted by the first filter 31, the filtered light is filtered again by the third filter 33 and finally received by the first light receiver 22.

[0049] In an optional example, a first mounting base 41 is provided between the first light transmitter 21 and the first light receiver 22. The first mounting base 41 is provided with a first groove. A first collimating lens 42 facing the second end of the base 1 is provided in the first groove. A first isolator 43 is provided on the first collimating lens 42. Both the first collimating lens 42 and the first isolator 43 are aligned with the first light transmitter 21.

[0050] Specifically, a first mounting base 41 is provided above the first optical receiver 22, and a first collimating lens 42 and a first isolator 43 are provided in the groove. A first filter 31 and a third filter 33 are installed in the groove on the first mounting base 41, forming a wave combining channel with the first collimating lens 42 and the first isolator 43.

[0051] In this embodiment, the first filter 31 on the first mounting base 41 will retain wavelength light within the range of 1310 to 1379 nm and filter out wavelength light within the range of 1260 to 1285 nm, and the third filter 33 will retain wavelength light within the range of 1260 to 1280 nm and filter out wavelength light within the range of 1310 to 1620 nm.

[0052] Furthermore, the light beam emitted by the first light transmitter 21 is filtered by the first collimating lens 42, the first isolator 43 and the first filter 31 in the slot of the first mounting base 41. The 1260-1285nm wavelength light filtered out by the first filter 31 will pass through the third filter 33 on the first mounting base 41 and finally be received by the first light receiver 22.

[0053] In an optional example, the first mounting base 41 has a first recess 61 on its side end face away from the base 1. The first recess 61 includes a first inclined surface and a first horizontal surface. The first filter 31 is disposed on the first inclined surface, and the third filter 33 is disposed on the first horizontal surface.

[0054] For example, the first mounting base 41 is provided with a first recessed surface 61 including a first inclined surface and a first horizontal surface. The first filter 31 is installed in the first inclined surface, and the third filter 33 is installed in the first horizontal surface. The two are in contact at the edge. The inclination angle of the first inclined surface relative to the first horizontal surface is 45°. Therefore, the first filter 31 is a 45° filter.

[0055] In an optional example, a second mounting base 51 is provided between the second optical transmitter 23 and the second optical receiver 24, and a second filter 32 is disposed on the second mounting base 51.

[0056] It should be noted that the height of the second filter 32 on the second mounting base 51 needs to be completely aligned with the first filter 31 in order to facilitate the transmission of collimated light and avoid light deflection that would affect the output of the optical signal.

[0057] In an optional example, a second collimating lens 52 is provided at one end of the second mounting base 51 near the second light emitter 23, and a second isolator 53 is provided on the second collimating lens 52. Both the second collimating lens 52 and the second isolator 53 are embedded in the second mounting base 51.

[0058] In an optional example, the second mounting base 51 is provided with a second facet 62 near the second optical transmitter 23, and the second facet 62 is provided with a fourth filter 34. The second mounting base 51 is provided with a third facet 63 near the second optical receiver 24, and the third facet 63 is provided with a fifth filter 35 and a sixth filter, and the second filter 32 is disposed in the third facet 63. The optical fiber signal includes a second optical fiber signal. The third wavelength optical signal is converted into a second optical fiber signal after passing through the fourth filter 34, the fifth filter 35, the sixth filter 36 and the second filter 32 in sequence, and is output by the adapter 25. The light source signal is converted into a fourth wavelength optical signal after passing through the second filter 32, the sixth filter 36 and the fifth filter 35 in sequence, and is received by the second optical receiver 24.

[0059] Specifically, in this embodiment, a second mounting base 51, which can be embedded in the base 1, is provided above the second optical transmitter 23 and the second optical receiver 24. A transmitting collimating lens, namely the second collimating lens 52, is assembled at the end of the second mounting base 51 connected to the base 1. The first optical transmitter 21 and the second optical transmitter 23 are aligned with the adapter 25. The light beam emitted from the LD port is filtered by the upper inclined second filter 32. The 1610±50nm wavelength light is completely refracted into the combining channel of the second mounting base 51, and then passes through the second collimating lens 52, the adjustment ring and the second isolator 53 in the channel. The fifth filter 35 filters and retains 50% of the light signal, and the retained portion of the light is filtered by the upper sixth filter 36 and the second filter 32 in sequence, and then output through the adapter 25 and the optical fiber.

[0060] Furthermore, the second optical receiver 24 includes a TO base for mounting the receiving chip and a cap covering the base. The base will lock the PD end mounting port of the base 1, i.e., the second optical receiving port 14, so that the cap can be embedded in the base 1. The end of the cap embedded in the base 1 is equipped with a receiving end collimating lens, i.e., the second collimating lens 52. A second filter 32, a sixth filter 36, a fifth filter 35 and a second mounting base 51 are provided between the second optical receiver 24 and the nearby adapter 25. The second mounting base 51 has a Z-shaped structure.

[0061] The second mounting base 51 is fixed to the base 1. The second filter 32, the sixth filter 36, the fifth filter 35 and the third filter 33 are installed in sequence on the Z-shaped slot. The optical transmission is carried out through a combined wave channel with the sixth filter 36 as the boundary between the upper and lower parts.

[0062] In this embodiment, the second filter 32 retains wavelengths within the range of 1250–1360 nm and filters out wavelengths within the range of 1600–1650 nm; the sixth filter 36 retains wavelengths within the range of 1600–1650 nm and filters out wavelengths within the range of 1250–1360 nm; while the fifth filter 35 retains 50% of wavelengths within the range of 1260–1620 nm and filters out 50%.

[0063] When the light source forms a collimated beam through the first collimating lens Lens at the adapter 25, the light filtered by the second filter 32 will be refracted and filtered sequentially by the sixth filter 36 and the fifth filter 35 below, and finally received by the first light receiver 22.

[0064] The second optical transmitter 23 includes a transmitter mounting base, i.e., a second transmitter port, which can be embedded in the second mounting base 51. A transmitter collimating lens is fitted at the end of the second mounting base 51 that is connected to the base 1. The beam emitted by the LD passes through the upper inclined fourth filter 34, and the 1610±50nm wavelength light is completely refracted into the combining channel of the second mounting base 51. It then passes sequentially through the second collimating lens 52, the adjustment ring, the second isolator 53, and the fifth filter 35 in the channel. The fifth filter 35 filters and retains 50% of the optical signal, and the retained portion of the light is filtered sequentially by the upper sixth filter 36 and the second filter 32, and then output through the adapter 25 and optical fiber.

[0065] Based on the aforementioned optical transceiver components, the collimated beam ensures the stability of the optical path transmission within the cavity of the base 1 and the high performance of the optical components. Furthermore, the isolator ensures that the signals from the receiving end and the transmitting end do not interfere with each other, enabling the 25G Quad-OSA (QOSA) to simultaneously possess the functions of 25G BiDi optical fiber communication and OTDR optical fiber network monitoring.

[0066] This application integrates OTDR monitoring functionality into fiber optic transmission system applications. The Quad-OSA (QOSA) integration technology is applicable to all single-fiber bidirectional fiber optic transmission systems, including 1G BiDi, 10G BiDi, 25G BiDi, G-PON, 10G-PON, 25G-PON, 50G-PON, etc., providing OTDR integrated optical transceiver components that better meet the needs of the optical communication market.

[0067] It should be noted that, in the embodiments of this application, the wavelength of light is merely exemplary, and the optical transceiver component of this application does not limit the specific wavelength to be filtered.

[0068] In an optional example, the first filter 31, the second filter 32, the fourth filter 34, and the fifth filter 35 all make an angle of 45° with the axis of the base 1, and the side of the first filter 31, the second filter 32, the fourth filter 34, and the fifth filter 35 near the first end of the base 1 is lower than the side near the second end of the base 1; the third filter 33 and the sixth filter 36 make an angle of 0° with the axis of the base 1.

[0069] In the embodiments of this application, the tilted filters are all tilted in the same direction and are all aligned to form a light transmission channel. The tilt angles are also all the same, at 45°, to ensure that the filtering and refraction channels of the light do not deviate and to ensure the stability of the light signal transmission.

[0070] In one possible implementation, the adapter 25 is provided with a third collimating lens 7, which is positioned toward the first end of the base 1.

[0071] As mentioned above, when receiving signals from an external light source, the signal needs to be input from the lens of the adapter 25. Therefore, the third collimating lens 7 provided here is used to form a light beam to facilitate the transmission of the light beam.

[0072] The optical transceiver assembly provided in this application can be used in a combo optical module (Combo ONU). The combo optical module includes a housing, an optical transceiver assembly, and a circuit board. The optical transceiver assembly and the circuit board are disposed inside the housing, and the optical transceiver assembly is electrically connected to the circuit board.

[0073] Furthermore, the circuit board is generally a rigid printed circuit board (PCB). Due to its relatively rigid material, the rigid printed circuit board can also perform load-bearing functions. For example, the rigid printed circuit board can stably support the chip; when the optical transceiver component is located on the circuit board, the rigid printed circuit board can also provide stable support; the rigid printed circuit board can also be inserted into the electrical connector in the host computer cage. Specifically, metal pins / gold fingers are formed on one end surface of the rigid printed circuit board for connection with the electrical connector; these are things that flexible circuit boards cannot easily achieve.

[0074] Furthermore, the optical transceiver components provided in this application can be applied to optical network devices, including OTDR (Time Domain Reflectometer).

[0075] Optionally, the optical network equipment may also include an optical line terminal (OLT) or an optical network unit (ONU).

[0076] The above-mentioned combined optical modules are placed in a chassis to form an optical network device. The optical network device can be an OLT, an ONU, or an optical transmission device in an optical transport network (OTN). The specific type is not limited here.
