Description

Technical Field

[0001] This application relates to the field of communication technologies, and in particular, to an optical module, an optical communication processing single board, a signal processing method, and an optical receiver. Background Art

[0002] With the development of communication technologies, the standards of passive optical fiber networks are constantly iterating. Before the terminal devices based on non-new-standard communication technologies deployed in the existing network are completely withdrawn from the network, the deployment of new-standard products will cause compatibility problems between different standard products, which will further make it difficult to promote and apply new-standard products. To solve this problem, it is necessary to locate and troubleshoot the terminal devices based on non-new-standard communication technologies in the existing network. However, the current related technologies cannot identify the terminal devices based on non-new-standard communication technologies, resulting in the inability to smoothly and orderly withdraw the terminal devices based on non-new-standard communication technologies before the terminal devices based on new-standard communication technologies go online, thus affecting the deployment speed of new-standard communication technologies.

[0003] Therefore, how to detect and identify the terminal devices based on non-new-standard communication technologies in the existing network when new-standard products are deployed, so as to complete the smooth and orderly withdrawal of the terminal devices based on non-new-standard communication technologies before the new-standard products go online and accelerate the online deployment of new-standard products has become an urgent technical problem to be solved. Summary of the Invention

[0004] Embodiments of this application provide an optical module, an optical communication processing single board, a signal processing method, and an optical receiver, which can complete the smooth and orderly withdrawal of the terminal devices based on non-new-standard communication technologies before the new-standard products go online and accelerate the online deployment of new-standard products.

[0005] To achieve the above objective, the embodiments of this application adopt the following technical solutions:

[0006] In a first aspect, an optical module is provided. The optical module includes a first optical receiver. The first optical receiver is configured to: receive a first optical signal. The wavelength range of the first optical signal is between 1284 nm and 1288 nm. Send a first electrical signal to an optical communication processing single board. The first electrical signal is an electrical signal carrying service information based on 50G PON communication technology, or the first electrical signal is a false-hop electrical signal of an EPON FP ONT.

[0007] In an embodiment of the present application, the optical module is configured to receive a first optical signal with a wavelength range between 1284 nm and 1288 nm and send a first electrical signal to the optical communication processing single board. When the first optical signal received by the optical module is transmitted by an ONT based on the 50G PON communication technology, the first electrical signal is an electrical signal carrying service information. When the first optical signal received by the optical module is transmitted by an EPON FP ONT, the first electrical signal is a false jump electrical signal. Therefore, when the optical communication processing single board detects that the first electrical signal is a false jump electrical signal, it can be determined that the current ONT transmitting the optical signal is an EPON FP ONT, so as to locate and troubleshoot the EPON FP ONT in the existing network, so as to achieve a smooth and orderly withdrawal of the EPON FP ONT before the ONT based on the 50G PON communication technology goes online, and accelerate the deployment of the ONT based on the 50G PON communication technology. At the same time, when the smooth and orderly withdrawal of the EPON FP ONT and the deployment of the ONT based on the 50G PON communication technology are completed, the optical module provided in this embodiment is still applicable to this scenario and can be used to receive the optical signal carrying service information transmitted by the ONT based on the 50G PON communication technology. Enhance the compatibility of the optical module in this embodiment with different usage scenarios.

[0008] In a possible implementation manner, the optical module further includes a second optical receiver. The second optical receiver is configured to: receive a second optical signal. The wavelength range of the second optical signal is between 1315 nm and 1320 nm. Send a second electrical signal to the optical communication processing single board.

In the embodiment of the present application, by adding a second optical receiver, the missed detection of the EPON FP ONT with a wavelength range between 1315 nm and 1320 nm is avoided, and the detection and recognition coverage rate is improved.

In the embodiment of the present application, by adding a fourth optical receiver for receiving optical signals with a wavelength range between 1260 nm and 1360 nm, after the EPON FP ONT is identified, before the ONT deployment under the 50G PON communication technology goes online, a time window for the operator to gradually phase out the EPON FP ONT is reserved. At the same time, when the smooth and orderly withdrawal of the EPON FP ONT is completed and the ONT deployment under the 50G PON communication technology is carried out, the fifth optical receiver is used to receive optical signals with a wavelength range between 1260 nm and 1280 nm and between 1290 nm and 1330 nm, avoiding frequent replacement of the optical module due to different usage scenarios.

[0055] It should be noted that the terms "first", "second", etc. involved in the embodiments of this application are only used for the purpose of distinguishing the same type of features, and cannot be understood as indicating relative importance, quantity, order, etc.

[0056] The terms "exemplary" or "for example" and other words involved in the embodiments of this application are used to represent examples, illustrations or explanations. Any embodiment or design solution described as "exemplary" or "for example" in this application should not be interpreted as being more preferred or having more advantages than other embodiments or design solutions. Exactly speaking, the use of words such as "exemplary" or "for example" is intended to present relevant concepts in a specific manner.

[0057] The terms "coupled" and "connected" involved in the embodiments of this application should be understood in a broad sense. For example, it can refer to a direct physical connection, or an indirect connection realized through electronic devices, such as a connection realized through resistors, inductors, capacitors or other electronic devices.

[0058] First, some basic concepts involved in the embodiments of this application are explained:

[0059] Passive Optical Network (PON): It is a fiber-based broadband access technology. It includes the Optical Line Terminal (OLT) on the central office side, the Optical Network Unit (ONU) on the user side, and the Optical Distribution Network (ODN), etc. When transmitting data, the OLT sends the data to multiple ONUs through the ODN, and each ONU only receives the data belonging to itself. The OLT assigns a unique Logical Link Identifier (LLID) to the registered ONUs, and the ONU only sends data within the time window assigned by the OLT. The ONU confirms the ownership of the data packet according to the LLID in the Media Access Control (MAC) frame. In this way, the ONU can identify data packets through the LLID. In PON technology, the ODN is the key part. It consists of passive devices such as optical splitters and optical fibers, and is responsible for connecting the OLT and the ONU. There are no active electronic devices and electronic power supplies in the ODN, so it has high reliability and low cost. At the same time, since the PON system uses a passive optical splitter for signal distribution, it does not require power supply and has higher reliability. PON technology includes different types such as Ethernet Passive Optical Network (EPON) and Gigabit-Capable Passive Optical Network (GPON), which use different encapsulation protocols and transmission rates to transmit data respectively.

[0060] Ethernet Passive Optical Network (EPON): It is a PON technology based on Ethernet, integrating the advantages of PON technology and Ethernet technology. It adopts a point-to-multipoint topology, replacing the traditional point-to-point structure, thus saving the amount of optical fiber used and management costs. EPON uses Ethernet technology and adopts the standard Ethernet frame format. EPON can carry current mainstream services without any conversion. Therefore, EPON is a technology suitable for the requirements of broadband access networks. In EPON, downstream data transmission adopts a broadcast mode, and upstream adopts Time Division Multiple Access (TDMA) access technology. The EPON frame format is compatible with the Ethernet data frame format of IEEE 802.3, and information such as timestamps and LLIDs is added to the Ethernet frame format.

[0061] Gigabit-Capable Passive Optical Network (GPON): GPON has advantages over EPON in terms of high speed and multi-services. It can transmit a larger bandwidth and support more users than EPON. GPON is based on the principle of wavelength-division multiplexing (WDM). Data information is carried by optical signals of different wavelengths on the same ODN network for data transmission. The downstream data stream is sent in a broadcast manner, while the upstream data stream is transmitted through TDMA.

[0062] Optical Network Terminal (ONT): It is usually used to convert optical signals into data signals in Fiber to the Home (FTTH). ONT is generally located at the user side and is used to convert the optical signals in the optical fiber into electrical signals so as to transmit data to user devices such as computers, telephones or TVs through copper wires or wireless means. There are usually no other network devices between ONT and ODN, so it can directly receive the data sent by OLT. The difference between ONU and ONT lies in their locations and applications. ONU is located between the user and ODN, while ONT is directly located in the user's home. In addition, ONU usually has multiple interfaces and can provide multiple services, while ONT focuses more on providing services such as high-speed Internet access, IPTV, voice, and WiFi.

[0063] Received Signal Strength Indicator (RSSI): It refers to the strength of a wireless signal and is usually used to evaluate the signal quality of a wireless communication link. The larger the RSSI value, the higher the received signal strength, and vice versa. In wireless network communication, RSSI can be used to measure the quality of a wireless signal and can be used to determine whether a wireless connection is stable.

[0064] Central wavelength: It refers to the central position of the wavelength distribution of laser output, also known as the average wavelength or central frequency. The central wavelength is a core indicator of the laser spectrum distribution, which describes the concentrated position of the laser wavelength. In spectral analysis, the central wavelength is an important parameter used to measure the wavelength characteristics of the laser. For a single-wavelength laser, the central wavelength is equal to the peak wavelength of the laser. The peak wavelength refers to the wavelength with the highest laser energy, that is, the main wavelength of the laser output. For a laser with multiple wavelengths, the central wavelength is the central position of the laser spectrum distribution, that is, the average value of multiple wavelengths. During the operation of the laser, the central wavelength will be affected by various factors, such as temperature, pressure, chemical concentration, etc. These factors will change the wavelength of the laser, thereby affecting the quality and performance of the laser. Therefore, the monitoring and control of the central wavelength are important means to ensure the performance of the laser.

[0065] Avalanche photo diode (APD): It is an optoelectronic device with characteristics such as high sensitivity, low noise, and fast response speed. It utilizes the avalanche multiplication effect to amplify weak photocurrents, thereby achieving highly sensitive photoelectric detection. APDs are usually used in fields such as optical fiber communication, lidar, and spectral analysis.

[0066] Combo: In the fields of computer science and networking, it usually refers to a device or system that combines two or more technologies. In a switch, Combo means optical and electrical multiplexing.

[0067] 10G Combo: It is an optical module that supports a transmission rate of 10 Gbps and can simultaneously support multiple transmission protocols, such as Ethernet, Fibre Channel, etc. This optical module can be used in various application scenarios, such as data centers, metropolitan area networks, local area networks, etc.

[0068] Three-mode coexistence Combo: It means combining two wavelengths in an optical module to achieve independent transmission and reception processing of GPON and XGS-PON optical signals. The three-mode coexistence Combo optical module is built with a wavelength multiplexer that can multiplex and demultiplex the 4 wavelengths required for the upstream and downstream of XGS-PON and GPON. Among them, XGS-PON and XG-PON use the same wavelengths, which are the upstream wavelength of 1270 nm and the downstream wavelength of 1577 nm, and GPON uses the upstream wavelength of 1310 nm and the downstream wavelength of 1490 nm.

[0069] Z-block Demultiplexing: A Z-block refers to a waveguide optical device that uses a collimator as the output end. The demultiplexing scheme of a Z-block is based on a thin-film filter (TFF). In this scheme, eight TFF filters are pasted in two groups on a rhombic prism. One group is used for wavelength division multiplexing, and the other group is used for wavelength division demultiplexing. The transmission wavelengths of the respective filters are 1271 nm, 1291 nm, 1311 nm, and 1331 nm.

Among them, XG-PON is an asymmetric PON, and the upstream / downstream rate of the PON port is 2.5G / 10G, while XGS-PON is a symmetric PON, and the upstream / downstream rate of the PON port is 10G / 10G. XGS-PON supports the hybrid access of three types of ONUs, namely GPON, XG-PON, and XGS-PON. Its upstream transmits data according to time slots, and the ONU sends data within the time slots permitted by the OLT.

[0071] Broadcast, Conference and Data Room System (BCDR): It is a multimedia communication system that can realize functions such as audio and video communication, data transmission, large-screen demonstration, and videophone conferencing. The BCDR system adopts a distributed structure and is composed of a central control unit, an audio and video matrix, an RGB matrix, a touch screen, a computer, etc., and has a two-way transmission function.

[0072] The embodiments of the present application provide an optical receiver, as Figure 1 shown. The optical receiver 1000 includes an optical module 100 and an optical communication processing single board 200. The optical module 100 is coupled to the optical communication processing single board 200. The optical module 100 is used to receive an optical signal and output an electrical signal. The optical communication processing single board 200 is used to analyze the electrical signal.

[0073] In some possible implementation manners, the optical receiver 1000 may be applied to at least three scenarios. Among them, the first application scenario: EPON FP ONT has not been decommissioned, and the 50G PON service has not been deployed and launched. The second application scenario: EPON FP ONT has been decommissioned, and the 50G PON service has been deployed and launched. The third application scenario: EPON FP ONT has not been decommissioned, and the 50G PON service has been deployed and launched.

[0074] In some examples, when the optical receiver 1000 is applied to the first application scenario: EPON FP ONT has not been decommissioned, and the 50G PON service has not been deployed and launched. This embodiment provides as Figure 2The first optical receiver 1000A shown includes a first optical module 100A and a first optical communication processing single board 200A. In the first optical receiver 1000A, the wavelength range of 10G EPON / EPON FP ONT is 1310±50nm. 10G EPON / EPON coexists in time division, with upstream time division multiplexing for receiving Figure 2 the signals of ONTs ① to ⑤, and the first optical receiver 1000A can communicate normally.

[0075] Exemplarily, the first optical module 100A includes a hardware driver (DRV), an electro-absorption modulated laser (EML), a distributed feedback laser (DFB), 10GBM (abbreviation for 10 gigabit multimedia sockets, which is a high-speed serial interface and can be used to connect storage devices and other network devices), 1.25GBM (abbreviation for 1.25 gigabit multimedia sockets, which is a high-speed serial interface and can be used to connect storage devices and other network devices), a limiting amplifier (LA), and a trans-impedance amplifier (TIA).

[0076] Exemplarily, the first optical receiver 1000A also includes a digital signal processor (DSP). The DSP can be set in the first optical module 100A or in the first optical communication processing single board 200A.

[0077] In some examples, when the optical receiver 1000 is applied to the second application scenario: EPON FP ONT ( Figure 2 ONTs ① and ③ therein) withdraw from the network, and 50G PON ( Figure 2 ONT ⑥ therein) service deployment goes live. The third upstream wavelength of 50G PON in the first optical receiver 1000A is 1286±2nm. 50G PON and 10G EPON / EPON coexist in wavelength division, resulting in a 10G EPON / EPON receiving wavelength range of 1260nm - 1280nm & 1290nm - 1330nm. Figure 2 The wavelengths of ONTs ②, ④, and ⑤ therein conform to the range of 1260nm - 1280nm & 1290nm - 1330nm, and the wavelength of ONT ⑥ conforms to 1286±2nm. Therefore, the EPON receiver receives the signals of ONTs ②, ④, and ⑤, and the 50G PON receiver receives the signal of ONT ⑥, and the first optical receiver 1000A can communicate normally.

[0078] In some examples, when the optical receiver 1000 is applied to the third application scenario: the EPON FP ONT has not been decommissioned, and the 50G PON service is deployed and launched. With the development of communication technologies, 50G TDM-PON will become the standard choice for the next generation of PONs, that is, the next generations of XG(S)-PON and 10G EPON are both 50G PONs. The deployment of 50G PON needs to consider the smooth evolution of the existing network, that is, considering that 10G Combo is commonly used in the existing network. The deployment of 50G PON requires the prior deployment of a triple-mode coexistence Combo at the OLT to be compatible with the previous two generations of ONTs. Considering the compatibility issue, the standard has formulated wavelength options for triple-mode wavelength division coexistence. In the 50G PON and GPON / 10G PON coexistence solution, wavelength reuse technology is adopted, and the wavelengths of the existing 10G EPON / EPON ONTs in the network are reused as the third uplink wavelength of 50G PON to achieve smooth evolution. This wavelength reuse technology enables operators to deploy without affecting the normal operation of the existing network and gradually upgrade the existing network to 50G PON. It solves the coexistence problem between 50G PON and GPON / 10GPON. However, problems occur in the triple-mode wavelength division coexistence of 50G PON and EPON / 10G EPON (mainly EPON). Specifically, due to the wavelength division coexistence of 50G PON and 10G EPON / EPON, the receiving wavelength range of 10G EPON / EPON is 1260nm - 1280nm & 1290nm - 1330nm, which causes the EPON FP ONT with wavelengths between 1284nm and 1288nm to malfunction. Therefore, to solve the problem of triple-mode wavelength division coexistence of 50G PON and EPON / 10G EPON (mainly EPON), it is necessary to locate and troubleshoot the EPON FP ONTs in the existing network so as to complete the smooth and orderly decommissioning of the EPON FP ONTs before the 50G ONTs are launched and accelerate the deployment of 50G PON. However, based on the current triple-mode coexistence optical module, it is technically impossible to identify the EPON FP ONTs.

[0079] In order to be able to locate and troubleshoot the EPON FP ONTs in the existing network to achieve the smooth and orderly decommissioning of the EPON FPONTs before the 50G ONTs are launched and accelerate the deployment of 50G PON. In some possible implementation manners, such as Figure 3As shown in the figure, this embodiment provides a second optical receiver 1000B, which includes a second optical module 100B and a second optical communication processing single board 200B. Among them, the second optical module 100B includes a first optical receiver 110B. The first optical receiver 110B is configured to: receive a first optical signal, where the wavelength range of the first optical signal is between 1284 nm and 1288 nm; send a first electrical signal to the second optical communication processing single board 200B; the first electrical signal is an electrical signal carrying service information based on 50G PON communication technology, or the first electrical signal is a false jump electrical signal (signal detection, SD) of EPON FPONT.

[0080] In some examples, the first optical signal with a wavelength range between 1284 nm and 1288 nm can be obtained through the solution as Figure 4 shown. As Figure 4 shown, the second optical module 100B may further include a first wavelength division structure 120B; the first wavelength division structure 120B is configured to receive a combined optical signal and obtain a first optical signal with a wavelength range between 1284 nm and 1288 nm from the combined optical signal.

[0081] Exemplarily, the second optical communication processing single board 200B includes a first communication controller 210B. The first communication controller 210B integrates 50G PON communication technology; the first communication controller 210B is configured to: receive a first electrical signal from the second optical module 100B; the first electrical signal is an electrical signal carrying service information based on 50G PON communication technology, or the first electrical signal is a false jump electrical signal of EPON FPONT; analyze the first electrical signal based on 50G PON communication technology and output a detection result, where the detection result is used to determine that the first electrical signal is an electrical signal carrying service information based on 50G PON communication technology, or the first electrical signal is a false jump electrical signal of EPON FPONT. Specifically, the first communication controller 210B can receive and process electrical signals of 12.5G, 25G, and 50G service information.

[0082] Exemplarily, the SD false jump information is bound to the EPON / 10G EPON dynamic bandwidth assignment (DBA) time slot or the EPON FPONT ID. The second optical communication processing single board 200B performs SD detection on the first electrical signal. If the SD jumps high, it can be determined that the corresponding remote transmitting device of this time slot is an EPON FPONT.

[0083] Exemplarily, as Figure 5As shown, the second optical module 100B further includes an optical transmitter 130B. The first communication controller 210B transmits a handshake signal to the 50G ONT through the optical transmitter 130B. The first communication controller 210B receives the first electrical signal and performs protocol analysis based on whether to send the handshake signal. After analysis, if the first electrical signal is received within the first preset time, the first electrical signal is an electrical signal carrying service information based on the 50G PON communication technology. If it is outside the first preset time, or the first communication controller 210B does not transmit a handshake signal to the 50G ONT through the optical transmitter 130B, the first electrical signal is a misjump electrical signal of the EPON FP ONT, and it can be determined that the peer transmitting device is the EPON FP ONT.

[0084] Exemplarily, to detect and identify the EPON FP ONT with a wavelength range between 1284 nm and 1288 nm, the first communication controller 210B can also receive the first electrical signal a preset number of times from the second optical module 100B at a preset period, and analyze the RSSI of the first electrical signal received a preset number of times. Obtain the fluctuation of the RSSI of the first electrical signal received a preset number of times; compare the maximum value in the RSSI fluctuations of the first electrical signal received a preset number of times with a preset threshold. If the maximum value in the RSSI fluctuations of the first electrical signal is greater than the preset threshold, it is determined that the first optical signal is emitted by the EPON FP ONT. Specifically, in this embodiment, the preset period can be 2 minutes, the preset number of times can be 10 times, and the preset threshold can be 3 dB. The specific values are not limited in this embodiment.

[0085] Such as Figure 3 、 Figure 4 and Figure 5The proposed solution mainly detects optical signals with wavelengths in the range of 1284 nm - 1288 nm. However, the wavelength range of EPON FP ONT is 1310 ± 50 nm. Specifically, considering: 1) For EPON FP ONT with a central wavelength above 1330 nm at room temperature, even if the low-temperature drift is 20 nm - 25 nm, it will have no impact on the 1286 nm 25G / 50G upstream reception. Therefore, only EPON FP ONT with a central wavelength below 1330 nm needs to be identified. 2) For EPON FP ONT with a central wavelength of 1280 nm at room temperature, false jump signals can definitely be detected at 1284 nm - 1288 nm. 3) For EPON FP ONT with a central wavelength near 1300 nm at room temperature, false jump signals can also definitely be detected on the first optical receiver 110B. 4) For EPON FP ONT with a central wavelength between 1305 nm - 1330 nm (the transition bands are 1310 - 1315 and 1320 - 1325) at room temperature, in the case of low-temperature drift, it may interfere with the 1286 nm 25G / 50G upstream reception and needs to be identified and excluded in advance and replaced before the 50G PON service is deployed and launched. So as Figure 3 shown, the proposed solution will at least cause missed detection of EPON FP ONT with a central wavelength between 1305 nm - 1330 nm (the transition bands are 1310 - 1315 and 1320 - 1325).

[0086] To avoid missed detection of EPON FP ONT with a central wavelength between 1305 nm - 1330 nm (the transition bands are 1310 - 1315 and 1320 - 1325) and improve the detection and identification coverage rate, in some possible implementation manners, such as Figure 6 shown, the second optical module 100B further includes a second optical receiver 140B. The second optical receiver 140B is configured to: receive a second optical signal with a wavelength range between 1315 nm - 1320 nm. Send a second electrical signal to the second optical communication processing single board 200B. The second electrical signal is an electrical signal based on EPON and / or 10G EPON communication technologies.

[0087] Exemplarily, such as Figure 7As shown, the second optical module 100B may further include a power splitter 150B and a second demultiplexing structure 160B. Among them, the power splitter 150B may be a 1×2 power splitter. The power splitter 150B is used to divide the optical signal energy of one path received by the second optical module 100B from the ONT into two or more paths to output optical signals with equal or unequal energy. The second demultiplexing structure 160B is used to receive the combined optical signal and obtain a second optical signal with a wavelength range between 1315 nm and 1320 nm from the combined optical signal. Specifically, the second demultiplexing structure 160B may be a 0-degree glass slide.

[0088] Exemplarily, the second optical communication processing single board 200B further includes a second communication controller 220B. The second communication controller 220B integrates EPON and / or 10G EPON communication technologies. It is used to receive a second electrical signal from the second optical module 100B. The second electrical signal is an electrical signal based on EPON and / or 10G EPON communication technologies. The second electrical signal is analyzed based on EPON and / or 10G EPON communication technologies to output a second detection result, and the second detection result is used to determine that the second electrical signal is an electrical signal based on EPON and / or 10G EPON communication technologies.

[0089] Exemplarily, to detect and identify an EPON FP ONT with a wavelength range between 1315 nm and 1320 nm, the second communication controller 220B may also receive the second optical signal a preset number of times from the second optical receiver 140B at a preset period, and analyze the RSSI of the second optical signal. Obtain the fluctuation of the RSSI of the second optical signal for a preset number of times. Compare the maximum value in the fluctuations of the RSSI of the second optical signal for a preset number of times with a preset threshold. If it is greater than the preset threshold, it is determined that the second optical signal is sent by the EPON FP ONT. Specifically, in this embodiment, the preset period may be 2 minutes, the preset number of times may be 10 times, and the preset threshold may be 3 dB.

[0090] Although for an EPON FP ONT with a central wavelength above 1330 nm at room temperature, even if there is a low-temperature drift of 20 nm - 25 nm, it will have no impact on the 1286 nm 25G / 50G upstream reception, but if these bands of EPON FP ONTs are not detected and identified, after the future 50G PON service is deployed and launched, the receivers in the range of 1290 nm - 1330 nm based on EPON and / or 10G EPON communication technologies will not be able to work stably. Therefore, EPON FP ONTs with a central wavelength above 1330 nm also need to be detected and identified.

[0091] In order to be able to detect and identify EPON FP ONTs with a central wavelength above 1330 nm, so that the detection and identification coverage extends to the long wavelength band of the central wavelength of EPON FP ONTs, further improving the detection and identification coverage rate and avoiding missed detections. In some possible implementation manners, such as Figure 8 shown, the second optical module 100B further includes a third optical receiver 170B. The third optical receiver 170B is configured to: receive a third optical signal, where the wavelength range of the third optical signal is between 1330 nm and 1360 nm. Send a third electrical signal to the second optical communication processing single board 200B. The third electrical signal is an electrical signal based on EPON and / or 10G EPON communication technologies.

[0092] In some examples, such as Figure 9 shown, the second optical module 100B may further include a third wavelength division structure 180B. The third wavelength division structure 180B can reflect: 1330 nm - 1340 nm & 1344 nm - 1360 nm, and transmit optical signals in the wavelength bands of 1340 nm - 1344 nm and above 1360 nm. It is used to receive the combined optical signal and obtain a second optical signal with a wavelength range between 1330 nm and 1340 nm and between 1344 nm and 1360 nm from the combined optical signal.

[0093] Exemplarily, such as Figure 10 shown, the second optical module 100B may further include a fourth wavelength division structure 190B. The fourth wavelength division structure 190B is used to receive the combined optical signal and obtain a second optical signal with a wavelength range between 1330 nm and 1360 nm from the combined optical signal. Specifically, the fourth wavelength division structure 190B may be a circulator to achieve the purpose of reducing optical path loss.

[0094] In some examples, the second communication controller 220B is further configured to receive a third electrical signal from the third optical receiver 170B; the third electrical signal is an electrical signal based on EPON and / or 10G EPON communication technologies. Analyze the third electrical signal based on EPON and / or 10G EPON communication technologies and output a third detection result. The third detection result is used to determine that the third electrical signal is an electrical signal based on EPON and / or 10G EPON communication technologies.

[0095] In some examples, to detect and identify an EPON FP ONT with an identification wavelength range between 1330 nm and 1360 nm, the second communication controller 220B can also receive a preset number of third optical signals from the third optical receiver 170B at a preset period, and analyze the RSSI of the third optical signals. Obtain the fluctuation of the RSSI of the preset number of third optical signals; compare the maximum value in the fluctuation of the RSSI of the preset number of third optical signals with a preset threshold. If it is greater than the preset threshold, it is determined that the third optical signal is sent by the EPON FP ONT. Specifically, in this embodiment, the preset period can be 2 minutes, the preset number can be 10 times, and the preset threshold can be 3 dB.

[0096] To avoid missed detection, in some possible implementation manners, it is also possible to consider that while alternately scheduling the EPON FP ONT and when the EPON FP ONT sends a 1.25G signal upstream, turn on the 50G PON 1342nm electro-absorption modulated laser (EML) and modulate a 1.25G non-return-to-zero code (NRZ) signal onto it. The 1342nm downstream signal will be injected into the EPON FP ONT laser and reflected back by the FP laser. The 1.25G signal modulated by 1342nm will cause signal interference to the normal 1.25G upstream signal of the FP EPON ONT, thereby causing packet loss or error codes on the 1.25G receiver in the full wavelength band of 1260nm - 1360nm, and further identifying and detecting possible "escaped" EPON FP ONTs.

[0097] Furthermore, to enhance the effect of introducing injection interference through the 1342nm downstream, it is possible to consider further turning off the 1342nm EML thermoelectric cooler (TEC) (note: the normal operating temperature of the EML is 50 degrees) or cooling to achieve a blue shift of the EML wavelength (towards a shorter wavelength), so that the 50G EML downstream interference light is closer to the central wavelength / gain peak of the EPON FP ONT laser.

[0098] In summary, in Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 and Figure 10In the illustrated embodiment, it is possible to locate and troubleshoot EPON FP ONTs in the existing network, so as to achieve a smooth and orderly withdrawal of EPON FP ONTs before the 50G ONT goes online, and accelerate the deployment of 50G PON. However, after the EPON FP ONT is identified and before the 50G PON service is deployed and goes online, a time window for the operator to gradually withdraw the FP EPON ONT needs to be reserved.

[0099] In order to ensure that FP EPON ONTs, 1270nm distributed feedback laser (DFB) EPON ONTs, and 1310 DFB EPON ONTs can all work properly during the time window. In some possible implementation manners, such as Figure 11 As shown, the second optical module 100B further includes a fourth optical receiver 1100B and a fifth optical receiver 1110B; wherein: the fourth optical receiver 1100B is configured to: receive a fourth optical signal and output a fourth electrical signal, and the wavelength range of the fourth optical signal is between 1260nm and 1360nm. The fourth electrical signal carries service information based on 10G EPON communication technology or EPON communication technology. The fifth optical receiver 1110B is configured to: receive a fifth optical signal and output a fifth electrical signal. The wavelength range of the fifth optical signal is between 1260nm - 1280nm and 1290nm - 1330nm. The fifth electrical signal carries service information based on 10G EPON communication technology or EPON communication technology.

[0100] In some examples, such as Figure 12 As shown, the second optical module 100B may further include a fifth wavelength division structure 1120B. The fifth wavelength division structure 1120B is configured to receive a combined optical signal and obtain a fifth optical signal with a wavelength range between 1260nm - 1280nm and 1290nm - 1330nm from the combined optical signal.

[0101] Exemplarily, the first wavelength division structure 120B and the fifth wavelength division structure 1120B jointly complete the Z-block wavelength division scheme as Figure 13 shown.

[0102] Specifically, the technical solution provided by this application can be applicable both after the EPON FP ONT is recognized and before the 50G PON service is deployed and launched, and also after the EPON FP ONT is retired from the network and the 50G ONT service is deployed and launched. In the scenario after the EPON FP ONT is recognized and before the 50G PON service is deployed and launched, the fourth optical receiver 1100B is used to receive optical signals in the full wavelength range between 1260 nm and 1360 nm. In the scenario after the EPON FP ONT is retired from the network and the 50G PON service is deployed and launched, the fifth optical receiver 1110B is used to receive optical signals in the wavelength ranges between 1260 nm and 1280 nm and between 1290 nm and 1330 nm. According to different usage scenarios, the fourth optical receiver 1100B or the fifth optical receiver 1110B can be set in advance, or alternatively, the fourth optical receiver 1100B and the fifth optical receiver 1110B can be switched by setting a gating circuit to achieve switching between different usage scenarios. Among them, the gating circuit can be set on the side of the second optical module 100B or on the side of the second optical communication processing single board 200B.

[0103] In some possible implementation manners, as Figure 14 shown, when the gating circuit is set on the side of the second optical communication processing single board 200B. The second optical communication processing single board 200B further includes a first gating circuit 230B. The first gating circuit 230B is used to receive a fourth electrical signal or a fifth electrical signal from the optical module. The fourth electrical signal is an electrical signal carrying service information based on EPON and / or 10G EPON communication technologies, and the fifth electrical signal is an electrical signal carrying service information based on EPON and / or 10G EPON communication technologies. The second communication controller 220B is further used to output a first control signal to the first gating circuit 230B when the detection result indicates that the first electrical signal is an electrical signal carrying service information based on 50G PON communication technology and the first gating circuit 230B receives the fourth electrical signal from the second optical module 100B. The first control signal is used to control the first gating circuit 230B to receive the fifth electrical signal. When the detection result indicates that the first electrical signal is a false jump electrical signal of the EPON FP ONT and the second optical communication processing single board 200B receives the fifth electrical signal from the first gating circuit 230B, a second control signal is output. The second control signal is used to control the first gating circuit 230B to receive the fourth electrical signal.

[0104] In some examples, by using the first gating circuit 230B, this embodiment also provides a solution for detecting and identifying an EPON FPONT, which specifically includes: performing two uplink transmission schedules on the EPON FPONT or the 10G asymmetric EPON FPONT. For the first time, through the first gating circuit 230B, the fifth optical receiver 1110B is gated to perform received power detection. For the second time, the fourth optical receiver 1100B is gated to perform received power detection, or vice versa. The gating order is not restricted here. By comparing the results of the two power detections, if the difference between the power detection results is greater than a preset threshold (such as >= 2 dB), it can be determined that the laser used by the corresponding EPON FPONT or 10G asymmetric EPON FPONT is an FP laser.

[0105] In some examples, the EPON FPONT can also be detected and identified by detecting the magnitude of the fluctuation of the signal intensity of the fourth electrical signal or the fifth electrical signal. Specifically, the second communication controller 220B receives the fourth optical signal a preset number of times from the fourth optical receiver 1100B or receives the fifth optical signal a preset number of times from the fifth optical receiver 1110B at a preset period, and analyzes the RSSI of the fourth electrical signal or the RSSI of the fifth electrical signal. The fluctuation of the RSSI of the fourth electrical signal or the fifth electrical signal for a preset number of times is obtained. The maximum value of the fluctuation of the RSSI of the fourth electrical signal or the fifth electrical signal for a preset number of times is compared with a preset threshold. If it is greater than the preset threshold, it is determined that the fourth optical signal or the fifth optical signal is emitted by the EPON FPONT. Specifically, in this embodiment, the preset period can be 2 minutes, the preset number of times can be 10 times, and the preset threshold can be 3 dB.

[0106] In some possible implementation manners, when the gating circuit is disposed on the second optical module 100B side. Such as Figure 15As shown, the second optical module 100B further includes a second gating circuit 1130B. The first gating end of the second gating circuit 1130B is used to input a fourth electrical signal, and the second gating end of the second gating circuit 1130B is used to input a fifth electrical signal. The common end of the second gating circuit 1130B is coupled to the first gating end or the second gating end of the second gating circuit 1130B through the gating end of the second gating circuit 1130B. When the second gating circuit 1130B receives a first control signal from the second optical communication processing single board 200B, the common end of the second gating circuit 1130B is coupled to the second gating end of the second gating circuit 1130B through the gating end of the second gating circuit 1130B to send the fifth electrical signal to the second optical communication processing single board 200B. When the second gating circuit 1130B receives a second control signal from the second optical communication processing single board 200B, the common end of the second gating circuit 1130B is coupled to the first gating end of the gating circuit through the gating end of the gating circuit to send the fourth electrical signal to the second optical communication processing single board 200B.

[0107] In some examples, as Figure 16 shown, the second gating circuit 1130B includes a first sub-gating circuit 1131B and a second sub-gating circuit 1132B. The second optical module 100B further includes a first electrical power splitter 1140B and a second electrical power splitter 1150B. The combining end of the first electrical power splitter 1140B is coupled to the output end of the fourth optical receiver 1100B. The combining end of the second electrical power splitter 1150B is coupled to the output end of the fifth optical receiver 1110B. The first gating ends of the first sub-gating circuit 1131B and the second sub-gating circuit 1132B are used to input multiple fourth electrical signals, and the second gating ends of the first sub-gating circuit 1131B and the second sub-gating circuit 1132B are used to input multiple fifth electrical signals.

[0108] In some examples, the second communication controller 220B is further configured to output a first control signal when the detection result is used to indicate that the first electrical signal is an electrical signal carrying service information based on the 50G PON communication technology, and the second optical communication processing single board 200B receives a fourth electrical signal from the second optical module 100B. The first control signal is used to control the second optical module 100B to send a fifth electrical signal.
