[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.

The embodiment of the present application can demultiplex three waves of different wavelengths through the AWG wavelength division multiplexer 13 in the optical component 1 to obtain split-wavelength signals, combine the three waves of different wavelengths through the optical component 1, and integrate three transceiver modules with different bandwidths into one optical module transceiver device through the 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.

[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] In a possible embodiment of the present application, the combiner component 14 includes 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.

[0047] 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.

[0048] It should be noted that, due to bandwidth influence, the third light cannot be the optical signal transmitted by the GPON transmitting unit.

[0049] 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.

[0050] 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.

[0051] 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.

[0052] That is to say, the third light cannot be the fourth light signal to avoid affecting the synthesis.

[0053] 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:

[0054] Combination 1: λ1 = 10G PON OLT TX (1575nm ~ 1581nm), λ2 = GPON OLT TX (1480nm ~ 1500nm), λ3 = 50G PON OLT TX (1300nm ~ 1344nm);

[0055] Combination 2: λ1 = 50G PON OLT TX (1300nm ~ 1344nm), λ2 = GPON OLT TX (1480nm ~ 1500nm), λ3 = 10G PON OLT TX (1575nm ~ 1581nm);

[0056] Combination 3: λ1 = 10G PON OLT TX (1575nm ~ 1581nm), λ2 = 50G PON OLT TX (1300nm ~ 1344nm), λ3 = GPON OLT TX (1480nm ~ 1500nm);

[0057] Combination 4: λ1=50G PON OLT TX (1300nm~1344nm), λ2=10G PON OLT TX (1575nm~1581nm), λ3=GPON OLT TX (1480nm~1500nm).

[0058] In a possible implementation manner of the present application, the optical component 1 further includes an AWG coupling lens 19 , a semiconductor optical amplifier (SOA) amplifier 18 , and an SOA coupling lens 17 .

[0059] Among them, the optical signal sent by the optical network unit is converted into converged light through the SOA coupling lens 17, and then coupled to the SOA amplifier 18. After amplification by the SOA amplifier 18, it is input to the AWG coupling lens 19, and after shaping by the AWG coupling lens 19, it is input to the AWG wavelength division multiplexer 13, and after total reflection of the AWG wavelength division multiplexer 13, it is received by the first receiving unit 211, the second receiving unit 221 and the third receiving unit 231.

[0060] The function of the SOA coupling lens 17 is to converge the received optical signal to obtain converged light. The function of the SOA amplifier 18 is to amplify the received optical signal. The function of the AWG coupling lens 19 is to shape the received optical signal, such as adjusting the propagation direction of the optical signal. The function of the AWG wavelength division multiplexer 13 is to separate the received optical signals of different wavelengths to obtain multiple single signals.

[0061] In this embodiment, after aggregating, amplifying, and shaping the received optical signals, the AWG wavelength division multiplexer 13 demultiplexes the optical signals sent by the optical network unit (Optical Network Unit, ONU) into three branches through waveguide branches, which are received by three receiving units.

[0062] It is worth noting that the ONU may include GPON ONU, 10GPON ONU and 50GPON ONU. Accordingly, the first optical signal may be an optical signal sent by the GPON ONU, the second optical signal may be an optical signal sent by the 10GPON ONU, and the third optical signal may be an optical signal sent by the 50GPON ONU.

[0063] In this embodiment, the AWG wavelength division multiplexer 13 can decompose and multiplex the received optical signal into three branches through waveguide branches, and convert it into electrical signals for output after being received by different receiving units, 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, so that the optical module transceiver device is compatible with three PONs with different rates.

[0064] In a possible implementation of the present application, the angle between the first surface of the AWG wavelength division multiplexer 13 facing the first receiving unit 211, the second receiving unit 221 and the third receiving unit 231 and the first direction is 41° to 48°, and the first direction is the transmission direction of the optical signal from the AWG coupling lens 19 to the first surface of the AWG wavelength division multiplexer 13, and the first surface is used to perform total reflection processing on the received light.

[0065] That is to say, the tail end face of the AWG wavelength division multiplexer 13 facing the first receiving unit 211, the second receiving unit 221 and the third receiving unit 231 can be designed to have an oblique angle of 41° to 48°, so that the optical wave signal in the waveguide is output from the waveguide after total reflection, and then coupled to the first receiving unit 211, the second receiving unit 221 and the third receiving unit 231 respectively to be converted into an electrical signal output.

[0066] In a possible implementation of the present application, the optical component 1 further includes 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.

[0067] 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.

[0068] 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.

[0069] 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.

[0070] 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 .

[0071] 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, is shaped by the wave combiner / demultiplexer lens 11 to form parallel light, is input to the wave combiner / demultiplexer glued prism 12, and is input to the AWG wavelength division multiplexer 13 after total reflection 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 transmitting through the wave combining / demultiplexer glued prism 12, and are transmitted to the wave combiner / demultiplexer convergence lens 11 after coupling through the wave combining / demultiplexer convergence lens 11 to the pin assembly 10.

[0072] The wave combiner / demultiplexer lens 11 is used to shape the received optical signal and output parallel light. The wave combiner / demultiplexer glued 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 total reflection; and transmit the optical signal input from the wave combiner 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.

[0073] In a possible implementation of the present application, the wave combining / splitting prism 12 may include a first transmission filter 125 and a first transmission reflection prism 126 , and the first hypotenuse of the first transmission filter 125 is bonded to the first hypotenuse of the first transmission reflection prism 126 .

[0074] Among them, the optical signal sent by the optical network unit is input from the first bottom edge of the first transmissive reflection prism 126, is totally reflected from the first hypotenuse of the first transmissive reflection prism 126 to the second hypotenuse of the first transmissive reflection prism 126, and is output from the second bottom edge of the first transmissive reflection prism 126 to the AWG wavelength division multiplexer 13 after total reflection from the second hypotenuse of the first transmissive reflection prism 126; 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 combining component 14 and then transmitted to the first bottom edge of the first transmission filter 125, are transmitted to the first transmission filter 125 through the first bottom edge of the first transmission filter 125, and then are transmitted to the first transmissive reflection prism 126 through the first hypotenuse of the first transmission filter 125, and are output from the first bottom edge of the first transmissive reflection prism 126 to the combining and decomposing convergence lens 11.
