[0036] In the following, in conjunction with the figures, an optical module transceiver provided in an embodiment of the present application is described in detail through specific embodiments and application scenarios.

[0037] like Figures 1 to 6 The figure is a schematic diagram of the structure of an optical module transceiver device provided in an embodiment of the present application. The optical module transceiver device may include: an optical component 1, a circuit processing unit 2 and a housing 3, wherein the optical component 1 and the circuit processing unit 2 are arranged in the housing 3, and the circuit processing unit 2 includes a first transceiver module 21, a second transceiver module 22 and a third transceiver module 23.

[0038] Among them, the first transceiver module 21 includes a first receiving unit 211 and a first transmitting unit 212, the second transceiver module 22 includes a second receiving unit 221 and a second transmitting unit 222, and the third transceiver module 23 includes a third receiving unit 231 and a third transmitting unit 232; the optical component 1 includes a wave splitting component 13, and the wave splitting component 13 is used to perform wave splitting processing on the optical signal sent by the received optical network unit, and send the first optical signal, the second optical signal and the third optical signal obtained after the wave splitting processing to the first receiving unit 211, the second receiving unit 221 and the third receiving unit 231 respectively; the first transmitting unit 212 transmits a fourth optical signal to the optical component 1, the second transmitting unit 222 transmits a fifth optical signal to the optical component 1, and the third transmitting unit 232 transmits a sixth optical signal to the optical component 1, and the optical component 1 combines the fourth optical signal, the fifth optical signal and the sixth optical signal and sends them to the external optical fiber; wherein the first transceiver module 21, the second transceiver module 22 and the third transceiver module 23 are three transceiver modules with different bandwidths.

[0039] It should be noted that the first transceiver module 21 can be a Gigabit-capable passive optical networks Optical Line Terminal (GPON OLT) transceiver module, the second transceiver module 22 can be a 10GPON OLT transceiver module, and the third transceiver module 23 can be a 50GPON OLT transceiver module.

[0040] Among them, the GPON receiving unit can receive an optical signal with a wavelength of 1290nm~1330nm, that is, a first optical signal, the GPON transmitting unit can transmit an optical signal with a wavelength of 1480nm~1500nm, that is, a fourth optical signal, the 10GPON receiving unit can receive an optical signal with a wavelength of 1260nm~1280nm, that is, a second optical signal, the 10GPON transmitting unit can transmit an optical signal with a wavelength of 1575nm~1580nm, that is, a fifth optical signal, the 50GPON receiving unit can receive an optical signal with a wavelength of 1284nm~1288nm, that is, a third optical signal, and the 50GPON transmitting unit can transmit an optical signal with a wavelength of 1340nm~1344nm, that is, a sixth optical signal.

[0041] That is to say, the optical module transceiver device provided in this embodiment can not only include the GPON transceiver module and 10GPON transceiver module in the related technology, but also include a higher-speed 50GPON transceiver module, and there is no need for an additional 50GPON module external combiner / splitter device. The three transceiver modules can be packaged in a small form factor pluggable double density (SmallForm-Factor Pluggable-Double Density, SFP-DD) transceiver device to achieve miniaturized packaging, and can achieve the coexistence of three generations of PON to meet upgrade requirements.

[0042] It should be noted that the three transceiver modules may also be PON transceiver modules of other rates, which shall be subject to actual application and is not specifically limited in this embodiment.

[0043] In an embodiment of the present application, the optical module transceiver device includes: an optical component 1, a circuit processing unit 2 and a housing 3, the optical component 1 and the circuit processing unit 2 are arranged in the housing 3, the circuit processing unit 2 includes a first transceiver module 21, a second transceiver module 22 and a third transceiver module 23, the first transceiver module 21 includes a first receiving unit 211 and a first transmitting unit 212, the second transceiver module 22 includes a second receiving unit 221 and a second transmitting unit 222, the third transceiver module 23 includes a third receiving unit 231 and a third transmitting unit 232, the optical component 1 includes a splitter component 13, and the splitter component 13 is used to send the received optical network unit The optical signal is subjected to wavelength division processing, and the first optical signal, the second optical signal and the third optical signal obtained after the wavelength division processing are sent to the first receiving unit 211, the second receiving unit 221 and the third receiving unit 231 respectively, the first transmitting unit 212 transmits the fourth optical signal to the optical component 1, the second transmitting unit 222 transmits the fifth optical signal to the optical component 1, and the third transmitting unit 232 transmits the sixth optical signal to the optical component 1, and the optical component 1 combines the fourth optical signal, the fifth optical signal and the sixth optical signal and sends them to the external optical fiber, wherein the first transceiver module 21, the second transceiver module 22 and the third transceiver module 23 are three transceiver modules with different bandwidths. The embodiment of the present application can split three waves of different wavelengths through the splitter component 13 of the optical component 1, and combine three waves of different wavelengths through the optical component 1. Through the splitting and combining capabilities of the optical component 1, three transceiver modules with different bandwidths are integrated into one optical module transceiver device, so that the transceiver device can be compatible with low-rate PON, high-rate PON and higher-rate PON, and can realize the coexistence of three generations of PON in one passive optical network, and can work simultaneously.

[0044] In a possible implementation of the present application, the optical component 1 also includes a pin component 10 and a combiner component 14; the fourth optical signal emitted by the first transmitting unit 212, the fifth optical signal emitted by the second transmitting unit 222, and the sixth optical signal emitted by the third transmitting unit 232 are combined by the combiner component 14 and then transmitted to the pin component 10, and then sent to the external optical fiber through the pin component 10.

[0045] That is to say, the optical signals emitted by the first transmitting unit 212, the second transmitting unit 222 and the third transmitting unit 232 can be combined by the combining component 14 in the optical module, so that the transceiver device provided in this embodiment can be compatible with three PONs of different rates, thereby realizing the coexistence of three generations of PONs in one passive optical network.

[0046] like Figure 5As shown, in a possible implementation of the present application, the wave splitting component 13 may include a first wave splitting filter 131, a second wave splitting filter 132, a third wave splitting filter 133 and a wave splitting prism 134, and the first bottom edge of the first wave splitting filter 131, the first bottom edge of the second wave splitting filter 132 and the first bottom edge of the third wave splitting filter 133 are all arranged to fit the first bottom edge of the wave splitting prism 134.

[0047] Among them, the optical signal sent by the optical network unit is input from the pin assembly 10, and is input to the first wave splitting filter 131 through the first bottom edge and the second bottom edge of the wave splitting prism 134. The third optical signal is transmitted from the second bottom edge of the first wave splitting filter 131 and received by the third receiving unit 231; the first optical signal and the second optical signal are input to the wave splitting prism 134 after total reflection from the second bottom edge of the first wave splitting filter 131, and then are input to the second wave splitting filter 132 after total reflection from the second bottom edge of the wave splitting prism 134, and the second optical signal is received by the second receiving unit 221 after transmission from the second bottom edge of the second wave splitting filter 132; the first optical signal is input to the wave splitting prism 134 after total reflection from the second bottom edge of the second wave splitting filter 132, and then is input to the third wave splitting filter 133 after total reflection from the second bottom edge of the wave splitting prism 134, and the first optical signal is received by the first receiving unit 211 after transmission from the second bottom edge of the third wave splitting filter 133.

[0048] That is to say, the optical signal sent by the optical network unit (ONU) can be processed by using the first splitter filter 131, the second splitter filter 132, the third splitter filter 133 and the splitter prism 134, wherein each splitter filter can only transmit the optical signal corresponding to it and reflect other optical signals, that is, the first splitter filter 131 can only transmit the third optical signal and fully reflect the first optical signal and the second optical signal, the second splitter filter 132 can only transmit the second optical signal and fully reflect the first optical signal, and the third splitter filter 133 can only transmit the first optical signal. The first bottom edge of the splitter prism 134 can transmit the optical signal, the second bottom edge of the splitter prism 134 facing the side of the pin assembly 10 can transmit the optical signal, and the second bottom edge of the splitter prism 134 facing the side of the first splitter filter 131, the second splitter filter 132 and the third splitter filter 133 can fully reflect the optical signal.

[0049] It is worth noting that ONU includes GPON ONU, 10GPON ONU and 50GPON ONU. Accordingly, the first optical signal is an optical signal sent by GPON ONU, the second optical signal is an optical signal sent by 10GPON ONU, and the third optical signal is an optical signal sent by 50GPON ONU.

[0050] In this embodiment, different optical signals can be demultiplexed through the demultiplexing filter and the demultiplexing prism 134 to obtain three single optical signals, which are respectively input into different receiving units and converted into electrical signals for output, so that the transceiver device can receive optical signals of three different wavelengths. That is, the optical module transceiver device in this embodiment can receive optical signals of three different bandwidths, thereby satisfying the compatibility of the optical module transceiver device with three PONs with different rates.

[0051] like Figure 2 and 6 As shown, in a possible implementation of the present application, the optical component 1 also includes a first wave splitting and converging lens 171, a second wave splitting and converging lens 172, a third wave splitting and converging lens 173, a first reflector, a second reflector and a third reflector, and the first reflector, the second reflector and the third reflector are all 45° reflectors.

[0052] Among them, the third optical signal is transmitted from the second bottom edge of the first wave splitting filter 131, transmitted to the first reflector after passing through the first wave splitting convergence lens 171, and is received by the third receiving unit 231 after being reflected by the first reflector; the second optical signal is transmitted from the second bottom edge of the second wave splitting filter 132, transmitted to the second reflector after passing through the second wave splitting convergence lens 172, and is received by the second receiving unit 221 after being reflected by the second reflector; the first optical signal is transmitted from the second bottom edge of the third wave splitting filter 133, transmitted to the third reflector after passing through the third wave splitting convergence lens 173, and is received by the first receiving unit 211 after being reflected by the third reflector.

[0053] That is to say, after the optical signal is transmitted through the wavelength splitting filter, it can be focused by the wavelength splitting and converging lens 17, so that the optical signal is more concentrated to avoid signal loss, and then transmitted to the corresponding receiving unit (i.e., the third receiving unit 231, the second receiving unit 221, and the first receiving unit 211) through the reflector 18 and received by the corresponding receiving unit.

[0054] The reflective sheet can make the optical signal turn, thereby shortening the size of the housing 3 in a first direction, where the first direction refers to the direction in which the optical signal sent by the optical network unit is incident on the optical component 1 .

[0055] like Figure 3As shown, in a possible embodiment of the present application, the combiner component 14 may include a first parallelogram prism 141, a second parallelogram prism 142 and a third parallelogram prism 143, the second hypotenuse of the first parallelogram prism 141 is arranged to fit the first hypotenuse of the second parallelogram prism 142, the second hypotenuse of the second parallelogram prism 142 is arranged to fit the first hypotenuse of the third parallelogram prism 143, and the first parallelogram prism 141, the second parallelogram prism 142 and the third parallelogram prism 143 are all 45° parallelogram prisms.

[0056] The first light is transmitted through the first base of the first parallelogram prism 141 to the first hypotenuse of the first parallelogram prism 141, and is transmitted to the second hypotenuse of the first parallelogram prism 141 after total reflection of the first hypotenuse of the first parallelogram prism 141, and is transmitted from the second hypotenuse of the first parallelogram prism 141 into the second parallelogram prism 142, and is transmitted through the second hypotenuse of the second parallelogram prism 142 into the third parallelogram prism 143, and is transmitted from the second base of the third parallelogram prism 143 to the pin assembly 10; the second light is transmitted through the first base of the second parallelogram prism 142 to the first hypotenuse of the second parallelogram prism 142, and is transmitted through the second parallelogram prism 142 into the third parallelogram prism 143. The third light ray is transmitted to the second hypotenuse of the second parallelogram prism 142 through total reflection from the first hypotenuse of the third parallelogram prism 142, and is transmitted into the third parallelogram prism 143 from the second hypotenuse of the second parallelogram prism 142, and is transmitted to the pin assembly 10 after total reflection through the second hypotenuse of the third parallelogram prism 143 and is transmitted from the second base of the third parallelogram prism 143; the third light ray is transmitted to the first hypotenuse of the third parallelogram prism 143 through the first base of the third parallelogram prism 143, and is transmitted to the second hypotenuse of the third parallelogram prism 143 after total reflection from the first hypotenuse of the third parallelogram prism 143, and is transmitted to the pin assembly 10 after total reflection through the second hypotenuse of the third parallelogram prism 143 and is transmitted from the second base of the third parallelogram prism 143.

[0057] It should be noted that, due to bandwidth influence, the third light cannot be the optical signal transmitted by the GPON transmitting unit.

[0058] In this embodiment, the combining component 14 is formed by gluing three 45-degree parallelogram prisms, wherein two gluing surfaces have transmission and reflection functions, the sides opposite to the gluing surfaces are reflection surfaces, the reflection surfaces have total reflection functions, and the sides adjacent to the gluing surfaces have transmission functions. Through the combining component 14, three types of optical signals can be combined into one beam and emitted.

[0059] In a possible implementation of the present application, the first transceiver module 21 is a gigabit passive optical network optical line terminal GPON OLT transceiver module, the second transceiver module 22 is a 10G PON OLT transceiver module, and the third transceiver module 23 is a 50GPON OLT transceiver module; the third light is the fifth optical signal or the sixth optical signal.

[0060] Among them, when the third light is the fifth light signal, the first light is the fourth light signal, and the second light is the sixth light signal; or when the third light is the fifth light signal, the first light is the sixth light signal, and the second light is the fourth light signal; when the third light is the sixth light signal, the first light is the fourth light signal, and the second light is the fifth light signal; or when the third light is the sixth light signal, the first light is the fifth light signal, and the second light is the fourth light signal.

[0061] That is to say, the third light cannot be the fourth light signal to avoid affecting the synthesis.

[0062] In a specific implementation of the present application, the wavelengths of the three PON OLTs are arranged from left to right as the first, second, and third optical signals (third light λ1, second light λ2, first light λ3), and the leftmost λ1 is not required to be a GPON OLT TX (1480nm~1500nm) optical signal. There are four arrangements and combinations of the three optical signal combinations from left to right:

[0063] Combination 1: λ1 = 10G PON OLT TX (1575nm ~ 1581nm), λ2 = GPON OLT TX (1480nm ~ 1500nm), λ3 = 50G PON OLT TX (1300nm ~ 1344nm);

[0064] Combination 2: λ1 = 50G PON OLT TX (1300nm ~ 1344nm), λ2 = GPON OLT TX (1480nm ~ 1500nm), λ3 = 10G PON OLT TX (1575nm ~ 1581nm);

[0065] Combination 3: λ1 = 10G PON OLT TX (1575nm ~ 1581nm), λ2 = 50G PON OLT TX (1300nm ~ 1344nm), λ3 = GPON OLT TX (1480nm ~ 1500nm);

[0066] Combination 4: λ1=50G PON OLT TX (1300nm~1344nm), λ2=10G PON OLT TX (1575nm~1581nm), λ3=GPON OLT TX (1480nm~1500nm).

[0067] like Figure 2 As shown, in a possible implementation of the present application, the optical component 1 may further include a collimating lens 16, a first isolator 151 and a second isolator 152, wherein the collimating lens 16 is used to output parallel light after shaping the input fourth optical signal, fifth optical signal and sixth optical signal.

[0068] Among them, the fifth optical signal emitted by the second transmitting unit 222 is input into the first isolator 151 after passing through the collimating lens 16, and then output to the pin assembly 10 after passing through the combiner assembly 14, wherein the first isolator 151 is used to prevent the fifth optical signal from being reflected back to the second transmitting unit 222; the sixth optical signal emitted by the third transmitting unit 232 is input into the second isolator 152 after passing through the collimating lens 16, and then output to the pin assembly 10 after passing through the combiner assembly 14, wherein the second isolator 152 is used to prevent the sixth optical signal from being reflected back to the third transmitting unit 232; the fourth optical signal emitted by the first transmitting unit 212 is input into the combiner assembly 14 after passing through the collimating lens 16, and then output to the pin assembly 10 after passing through the combiner assembly 14.

[0069] The optical signals emitted by the first emitting unit 212, the second emitting unit 222, and the third emitting unit 232 are processed by the collimating lens 16 to obtain parallel light, so that the light can vertically enter the multiplexing component 14, so that the fourth optical signal, the fifth optical signal, and the sixth optical signal can be better combined into a beam of light. The optical signal can also pass through an isolator before entering the multiplexing component 14 to prevent the emitted optical signal from being emitted back and affecting the output quality of the optical signal.

[0070] It is worth noting that, since the transmission rate of the GPON transmitting unit is relatively low, the optical signal emitted by the GPON transmitting unit may not be processed by the isolator, thereby reducing the cost.

[0071] In a possible implementation manner of the present application, the optical component 1 further includes a wave combining / splitting converging lens 11 and a wave combining / splitting cementing prism 12 .

[0072] Among them, the optical signal sent by the optical network unit is transmitted from the pin assembly 10 to the wave combiner / demultiplexer lens 11, and is formed into parallel light after being shaped by the wave combiner / demultiplexer lens 11, and is input into the wave combiner / demultiplexer glued prism 12, and is input into the wave splitter assembly 13 after multiple total reflections of the wave combiner / demultiplexer glued prism 12; the fourth optical signal emitted by the first transmitting unit 212, the fifth optical signal emitted by the second transmitting unit 222, and the sixth optical signal emitted by the third transmitting unit 232 are combined by the wave combining assembly 14 and then transmitted to the wave combiner / demultiplexer glued prism 12, and are transmitted to the wave combiner / demultiplexer convergence lens 11 after being transmitted through the wave combining / demultiplexer glued prism 12, and are transmitted to the pin assembly 10 after being coupled by the wave combining / demultiplexer convergence lens 11.

[0073] The wave combining and demultiplexing lens 11 is used to shape the received optical signal and output parallel light. The wave combining and demultiplexing prism 12 can process incident light from different directions differently, and output the optical signal input from the pin assembly 10 at the opposite side after multiple total reflections; and transmit the optical signal input from the wave combining assembly 14. This allows the incident light from different directions to be processed, so that the optical signal incident to the optical module transceiver and the optical signal emitted by the optical module transceiver do not affect each other.

[0074] like Figure 4 As shown, in a possible embodiment of the present application, the wave combining and decomposing glued prism 12 may include a transmitting and receiving wave splitting filter 121, a reflecting filter 122, a transmitting filter 123 and a transmitting and reflecting prism 124, and the first bottom edge of the transmitting and receiving wave splitting filter 121, the first bottom edge of the reflecting filter 122 and the first bottom edge of the transmitting filter 123 are all arranged to fit the first bottom edge of the transmitting and reflecting prism 124.

[0075] The optical signal sent by the optical network unit is input from the second bottom edge of the transmissive reflection prism 124, input to the transmitting and receiving wave splitting filter 121 through the first bottom edge of the transmissive reflection prism 124, and then through the first bottom edge of the transmitting and receiving wave splitting filter 121 after total reflection from the second bottom edge of the transmissive reflection prism 124. After total reflection from the second bottom edge of the transmissive reflection prism 124, the optical signal is input to the reflective filter 122 from the first bottom edge of the transmissive reflection prism 124. After total reflection from the second bottom edge of the reflective filter 122, the optical signal is input to the transmissive reflection prism 124 through the first bottom edge of the reflective filter 122. After total reflection from the second bottom edge of the transmissive reflection prism 124, the optical signal is input to the transmissive reflection prism 124 through the first bottom edge of the reflective filter 122. The optical signal is input from the first bottom edge of the transmissive-reflective prism 124 to the transmissive filter 123, and is transmitted to the wave splitting component 13 via the second bottom edge of the transmissive-reflective prism 123; the fourth optical signal emitted by the first transmitting unit 212, the fifth optical signal emitted by the second transmitting unit 222, and the sixth optical signal emitted by the third transmitting unit 232 are combined by the wave combining component 14 and then transmitted to the second bottom edge of the transmitting-receiving wave splitting filter 121, and is transmitted to the transmitting-receiving wave splitting filter 121 via the second bottom edge of the transmitting-receiving wave splitting filter 121, and then is input to the transmissive-reflective prism 124 via the first bottom edge of the transmissive-reflective prism 124, and is transmitted through the second bottom edge of the transmissive-reflective prism 124 and input to the wave combining and splitting converging lens 11.

[0076] In this embodiment, optical signals from different directions can be processed by the transmitting and receiving wave splitting filter 121, the reflecting filter 122, the transmitting filter 123 and the transmitting and reflecting prism 124, so that the optical signal incident to the optical module transceiver is input from the transmitting and reflecting prism 124, and then is totally reflected by the transmitting and receiving wave splitting filter 121, the transmitting and reflecting prism 124, the reflecting filter 122 and the transmitting and reflecting prism 124 in sequence, and then is transmitted from the transmitting filter 123 to the wave splitting component 13 for wave splitting processing. The outgoing optical signal is incident from the transmitting and receiving wave splitting filter 121, and then is transmitted to the wave combining and decomposing converging lens 11 through the transmitting and reflecting prism 124. The wave combining and decomposing cementing prism 12 can process incident light from different directions, so that the optical signal incident to the optical module transceiver and the optical signal emitted by the optical module transceiver do not affect each other.

[0077] In a possible implementation of the present application, the incident angle of the optical signal sent by the optical network unit to the wavelength combining and decomposing glued prism 12 is 6° to 20°; the incident angle of the optical signal sent by the optical network unit to the wavelength decomposition component 13 is 2° to 8°.

[0078] In a specific embodiment of the present application, three types of upstream optical signals GPON OLT RX upstream receiving light (first optical signal λ6=1290nm~1330nm), 10G PON OLT RX upstream receiving optical signal (second optical signal λ5=1260nm~1280nm), and 50G PON OLT RX upstream receiving optical signal (third optical signal λ4=1284nm~1288nm) are input from the pin assembly 10 into the optical assembly 1 and are shaped into parallel light by the wave combining and decomposing converging lens 11, and then are input into the wave splitting assembly 13 after multiple total reflections by the wave combining and decomposing cemented prism 12, and the incident angle is 2~8°. The three-wavelength signal first propagates to the splitter prism 134, and then is transmitted to the first splitter filter 131 after being transmitted through the splitter prism 134. The first splitter filter 131 transmits the 50G PON OLT RX (λ4=1284~1286nm) and totally reflects the other two wavelength signals. The transmitted wavelength λ4=1284~1286nm is focused by the first splitter convergence lens 171, and then the optical path is turned 90 degrees by the first reflector, and then received by the 50G PON OLT RX receiving chip (i.e., the third receiving unit 231), and converted into an electrical signal output optical component 1; the other two reflected light wave signals are transmitted to the splitter prism 134 after being reflected, and then transmitted to the second splitter filter 132 after being totally reflected by the splitter prism 134. The second splitter filter 132 focuses the 10G PON OLT RX (λ5=1260-1280nm) plays a transmission role and has a total reflection effect on other wavelength signals. The transmission wavelength λ5=1260-1280nm is focused by the second wave splitting convergence lens 172, and then the optical path is turned 90 degrees by the second reflector, and is received by the 10G PON OLT RX receiving chip (i.e., the second receiving unit 221), and converted into an electrical signal output optical component 1; similarly, the GPON OLT RX (λ6=1290-1330nm) is totally reflected by the second wave splitting filter 132, input to the wave splitting prism 134, and then totally reflected by the wave splitting prism 134, and then input to the third wave splitting filter 133, transmitted by the third wave splitting filter 133, and then focused by the third wave splitting convergence lens 173, and then the optical path is turned 90 degrees by the third reflector, and is received by the GPON OLT RX receiving chip (i.e., the first receiving unit 211), and converted into an electrical signal output optical component 1.

[0079] The optical module transceiver device provided in the embodiment of the present application can integrate three transceiver modules with different bandwidths into one transceiver device through the wave splitting and combining capabilities of the optical component 1, so that the transceiver device can be compatible with low-rate PON, high-rate PON and higher-rate PON, and can realize the coexistence of three generations of PON in one passive optical network and can work simultaneously.
