[0001] This disclosure relates to the field of communication technology, and in particular to a signal access device and a signal transmission system. Background Technology

[0002] With the continuous development of communication technology, users' demand for network bandwidth continues to grow.

Detailed Implementation

[0030] The exemplary embodiments of this disclosure are described below with reference to the accompanying drawings, including various details of the embodiments to aid understanding, and should be considered merely exemplary. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of this disclosure. Similarly, for clarity and brevity, descriptions of well-known functions and structures are omitted in the following description.

[0031] The signal access device and signal transmission system of the present disclosure are described below with reference to the accompanying drawings.

[0032] Figure 1 is a schematic diagram of the structure of a signal access device provided in an embodiment of this disclosure.

[0033] As shown in Figure 1, the signal access device includes a signal separation module 1 and a transmission module 2, wherein: the signal separation module 1 is configured on the optical path corresponding to at least one target service port a, and is used to separate the mixed optical signal transmitted in the optical path into different optical paths according to the transmission rate; the transmission module 2 is used to transmit the different service optical signals through their respective corresponding optical paths.

[0034] In some embodiments, target service port a is a port in an optical communication network used for optical signal interaction. Target service port a belongs to the port of optical line terminal equipment 11, and its type includes, but is not limited to, a Gigabit Passive Optical Network (GPON) port, a 10 Gigabit Passive Optical Network (10G PON) port, etc.; the corresponding optical line is an optical fiber link used for transmitting optical signals; the hybrid optical signal is a collection of multiple service optical signals with different transmission rates transmitted simultaneously in the same optical line, for example, simultaneously including a GPON optical signal with a transmission rate of 1.25Gbps and / or a 10G PON optical signal with a transmission rate of 10Gbps and / or a 50G PON hybrid optical signal with a transmission rate of 50Gbps; the signal separation module 1 is an optical device with the function of separating optical signals according to transmission rate, and its implementation includes, but is not limited to, using wavelength division multiplexing (WDM). Division Multiplexing (WDM) devices can specifically filter and separate mixed optical signals by selecting center wavelength filtering channels corresponding to optical signals of different rates, thereby separating single optical signals of different rates onto different optical paths for transmission; Transmission module 2 is a module with optical signal transmission adaptation function, which can establish a connection with the corresponding optical line through the optical interface to realize the split transmission of different optical signals (original optical line A and newly added optical line B). Specifically, it can match the corresponding transmission link interface according to the transmission parameters of different optical signals (such as transmission rate, wavelength, etc.) to ensure stable transmission of optical signals to gateway 13.

[0035] Through the above structure, the signal separation module 1 can accurately separate different service optical signals from the mixed optical signals according to their transmission rates. Then, the transmission module 2 transmits each type of service optical signal through its corresponding optical line, realizing the independent transmission of service optical signals at different rates. Its beneficial effects are: First, it improves the coverage and access range of service signals, ensuring the stability and reliability of the transmission of various service optical signals; second, it eliminates the need for overall modification of the target service port and optical lines, achieving the splitting of optical signals at different rates simply by configuring the signal separation module 1 and the transmission module 2, reducing the cost of upgrading and transforming the optical communication network; third, it adapts to the signal processing requirements of at least one target service port, and can be flexibly applied to single-port or multi-port optical signal separation transmission scenarios, improving the adaptability and scalability of the equipment; fourth, it provides a foundation for the individual optimization processing of high-bandwidth service optical signals, facilitating targeted processing of the separated optical signals according to different service requirements, supporting the optical communication network's ability to carry diverse services.

[0036] Figure 2 shows a schematic diagram of another signal access device provided in an embodiment of this disclosure.

[0037] As shown in Figure 2, the target service port a includes a first service port a1; the signal separation module 1 is configured on at least one optical path corresponding to the first service port a1, and is used to separate the mixed optical signal transmitted in the optical path into a first service optical signal and a second service optical signal; wherein the transmission rate of the second service optical signal is different from the transmission rate of the first service optical signal.

[0038] In some embodiments, the first service port a1 may be selected from, but is not limited to, a GPON port or a 10G PON port; the corresponding first service optical signal is a reference rate optical signal adapted to the first service port a1, such as a 1.25Gbps optical signal corresponding to a GPON port and / or a 10Gbps optical signal and / or a 50Gbps optical signal corresponding to a 10G PON port; the second service optical signal is an optical signal with a transmission rate higher than the first service optical signal. For example, when the first service port a1 is a 10Gbps optical signal corresponding to a GPON port, the second service optical signal may be selected from a 50Gbps 50Gbit Passive Optical Network (50G PON). The signal separation module 1 is configured on the optical path corresponding to the first service port a1, specifically in series at the connection node between the first service port a1 and the optical path, to achieve real-time separation of the mixed optical signals in the optical path. The separation process involves first identifying the optical signal components of different rates in the mixed optical signal, and then separating the first service optical signal and the second service optical signal through the corresponding separation mechanism. For example, a WDM1r device can be used as the signal separation module 1. This device has a specific wavelength separation channel and can accurately separate the 50G PON optical signal (second service optical signal) and the GPON optical signal (first service optical signal). It should be noted that the above examples are only illustrative and do not limit the specific content.

[0039] The above structure clarifies the specific type of the target service port as the first service port a1, and separates the mixed optical signal into a first service optical signal and a second service optical signal, making the object and result of signal separation more targeted. Its beneficial effects are: First, it further refines the application scenarios of signal separation, adapting to the deployment architecture based on the first service port in optical communication networks, reducing the difficulty of device and network adaptation; second, by clearly defining two different rate service optical signals, it provides a clear basis for distinguishing the differentiated transmission and processing of the two optical signals; third, the corresponding configuration of signal separation module 1 and the first service port a1 enables precise separation of the transmitted signal of each first service port, avoiding separation errors caused by multi-port signal aliasing; fourth, it is compatible with existing first service ports in the network, achieving the separation of the new rate service optical signal (second service optical signal) without replacing the port, ensuring the smoothness of network upgrades.

[0040] Please refer to Figure 2. The transmission module 2 is also used to transmit the first service optical signal through the original optical line A and to transmit the second service optical signal through the newly added optical line B.

[0041] In some embodiments, the original optical line A is the optical line originally connected to the first service port a1, that is, the fiber optic link already deployed in the optical communication network for transmitting the first service optical signal. It can use the fiber optic resources and connection relationship of the link without additional laying. The newly added optical line B is a fiber optic link specially added for the second service optical signal. Its laying method can be determined according to the actual network deployment requirements and is not limited to any specific method, including but not limited to laying along the routing direction of the original optical line A, or planning a separate route according to the transmission destination of the second service optical signal. The transmission module 2 connects the original optical line A and the newly added optical line B through two independent transmission channels respectively. The channel connected to the original optical line A is adapted to the transmission parameters of the first service optical signal, and the channel connected to the newly added optical line B is adapted to the transmission parameters of the second service optical signal. After receiving the two optical signals separated by the signal separation module 1, the transmission module 2 guides the first service optical signal to the original optical line A and the second service optical signal to the newly added optical line B through channel switching or decoupling mechanism, so as to realize the independent transmission of the two optical signals.

[0042] The above structure achieves transmission isolation between the first and second service optical signals on different optical paths. Its beneficial effects are as follows: First, the continued use of the original optical line A ensures the normal transmission of the first service optical signal, avoiding interruptions to existing services due to the processing of new services and guaranteeing network service continuity. Second, the newly added optical line B provides a dedicated transmission link for the second service optical signal, allowing for the selection of an appropriate fiber type based on the transmission rate and bandwidth requirements of the second service optical signal, ensuring its transmission quality. Third, the isolation of the transmission links for the two optical signals completely eliminates transmission interference between optical signals of different rates, improving the transmission stability and efficiency of both types of service optical signals. Fourth, the new optical line B can be flexibly configured, allowing for on-demand deployment based on the coverage area and user distribution of the second service optical signal, reducing the cost waste of link construction. Fifth, it provides an independent link foundation for the separate processing of the second service optical signal, avoiding any impact on the first service optical signal transmitted on the original optical line.

[0043] Please refer to Figure 2. The signal access device further includes a signal processing module 3. The signal processing module 3 is configured on the newly added optical line B and is used to process the second service optical signal and transmit the processed second service optical signal to the second service port b.

[0044] In some embodiments, the signal processing module 3 is a module with optical signal enhancement, aggregation, and splitting functions, configured on the newly added optical line B. Specifically, it can be set in the link of the newly added optical line B between the signal separation module 1 and the second service port b to realize mid-course processing of the second service optical signal. The second service port b is a port adapted for the transmission of the second service optical signal. For example, when the second service optical signal is a 50G PON optical signal, the second service port b is a 50G PON port or a 50G PON COMBO port. The processing methods of the signal processing module 3 for the second service optical signal include, but are not limited to, optical power amplification, signal aggregation, and signal splitting. The specific processing method can be determined according to the transmission requirements of the second service optical signal. For example, when there is power attenuation during the transmission of the second service optical signal, power amplification is performed; when there are multiple second service optical signals that need to be aggregated for transmission, aggregation is performed. It should be noted that the above examples are only illustrative and do not limit the specific content.

[0045] Through the above structure, targeted processing of the second service optical signal is achieved, ensuring the quality of the second service optical signal transmission to the second service port b. Its beneficial effects are as follows: First, the addition of signal processing module 3 can compensate for the transmission loss of the second service optical signal in the newly added optical line B, improving the transmission distance and reception quality of the second service optical signal; second, it can perform adaptation processing on the second service optical signal according to the reception requirements of the second service port b, ensuring the matching degree between the second service optical signal and the second service port b, and achieving stable connection between the two; third, the signal processing module 3, configured on the newly added optical line B, will not affect the first service optical signal transmitted on the original optical line A, ensuring the normal operation of existing services; fourth, it provides the possibility for centralized access of multiple second service optical signals, which can be aggregated and transmitted to a single second service port b through the aggregation function of signal processing module 3, improving the resource utilization of the second service port b; fifth, the flexible processing method can adapt to different types of second service optical signal requirements, improving the versatility and scalability of the equipment.

[0046] Please refer to Figure 2. The signal processing module 3 includes an optical splitting unit 31 and an optical amplification unit 32. The optical amplification unit 32 is configured between the signal separation module 1 and the optical splitting unit 31, and is used to amplify and compensate the second service optical signal separated by the signal separation module 1, and transmit the amplified and compensated second service optical signal to the optical splitting unit 31. The optical splitting unit 31 is configured between the second service port b and the optical amplification unit 32, and is used to converge the amplified and compensated second service optical signal, and transmit the converged second service optical signal to the second service port b.

[0047] In some embodiments, the optical splitting unit 31 is an optical device with optical signal convergence or splitting function, which is implemented in ways including but not limited to using an optical split coupler, which can couple multiple input optical signals into one output optical signal; the optical amplification unit 32 is a device with optical signal power amplification function, which can amplify the power of the input optical signal and compensate for the loss of the optical signal during transmission; the optical amplification unit 32 is configured between the signal separation module 1 and the optical splitting unit 31, that is, the output end of the optical amplification unit 32 is connected to the input end of the optical splitting unit 31, and each optical amplification unit 32 is connected to one second service optical signal separated by the signal separation module 1; its working process is that the multiple second service optical signals separated by the signal separation module 1 enter the corresponding optical amplification unit 32, and after being amplified and compensated by the optical amplification unit 32, they are transmitted to multiple input ports of the optical splitting unit 31. The optical splitting unit 31 is configured between the second service port b and the optical amplification unit 32, and the optical splitting unit 31 converges the multiple amplified second service optical signals into one, which is finally transmitted to the second service port b.

[0048] Through the above structure, amplification, compensation, and converged transmission of multiple secondary service optical signals are achieved. Its beneficial effects are: First, the optical amplification unit 32 amplifies and compensates each secondary service optical signal individually before convergence, accurately compensating for signal loss during transmission and avoiding overall transmission quality degradation due to insufficient power in some signals after convergence. Second, the convergence function of the optical splitter unit 31 can aggregate multiple secondary service optical signals and transmit them to a single secondary service port b, enabling the access of secondary service optical signals corresponding to multiple first service ports a1 to a single secondary service port b. This solves the problem of idle resources on the secondary service port b caused by traditional one-to-one port replacement, improving efficiency. The system improves the resource utilization of the second service port b; third, the combination of optical splitting unit 31 and optical amplification unit 32 can adapt to the processing needs of multiple second service optical signals, eliminating the need to configure a separate second service port b for each second service optical signal, thus reducing the deployment cost of the second service port b in network construction; fourth, the use of optical splitting devices and optical amplification devices ensures the stability and reliability of signal processing, while reducing the difficulty of equipment research and development and production; fifth, the amplification compensation processing increases the transmission distance of the second service optical signal, making the laying range of the newly added optical line B wider and improving the network coverage capability.

[0049] Please refer to Figure 2. The number of optical amplification units 32 is the same as the number of received second service optical signals.

[0050] In some embodiments, when the signal access device needs to process N second service optical signals (N is a positive integer), N optical amplification units 32 are configured accordingly, with each optical amplification unit 32 individually connected to one second service optical signal. For example, when there are three second service optical signals separated by the signal separation module 1 that need to be processed, three optical amplification units 32 are configured, each connected to the transmission link of one of the three second service optical signals. Each second service optical signal is amplified and compensated separately by one optical amplification unit 32 before being connected to the three input ports of the optical splitting unit 31. The number of optical amplification units 32 can be flexibly adjusted according to the actual number of second service optical signals accessed. The matching method between the number of optical amplification units 32 and the number of second service optical signals can be achieved through the device's expandable interface, facilitating the addition or reduction of the number of optical amplification units 32 according to service expansion requirements. It should be noted that the above examples are merely illustrative and do not limit the specific content.

[0051] Through the above structure, precise matching between the optical amplification unit 32 and the number of second service optical signals is achieved. Its beneficial effects are as follows: First, each second service optical signal can receive individual amplification and compensation processing. The amplification factor of the optical amplification unit 32 can be adjusted specifically according to the loss of each signal, ensuring power consistency after amplification and improving the overall transmission quality after multiple signals are converged. Second, it avoids signal interference or uneven amplification caused by sharing the optical amplification unit 32, ensuring independent processing of each second service optical signal. Third, the flexible quantity matching method can adapt to the needs of different service scales. When the number of second service optical signals is small, there is no need to configure extra optical amplification units 32, reducing equipment costs. When services expand and the number of second service optical signals increases, optical amplification units 32 can be added as needed, improving equipment scalability. Fourth, a failure of a single optical amplification unit 32 only affects the corresponding second service optical signal and will not affect the entire signal processing module 3, improving the fault tolerance and reliability of the equipment.

[0052] Please refer to Figure 2. The optical splitter unit 31 is configured between the signal separation module 1 and the optical amplification unit 32. It performs convergence processing on the second service optical signal and transmits the converged second service optical signal to the optical amplification unit 32. The optical amplification unit 32 is configured between the second service port b and the optical splitter unit 31. It is used to amplify and compensate the converged second service optical signal and transmit the amplified and compensated second service optical signal to the second service port b.

[0053] In some embodiments, this embodiment provides another configuration of the optical splitter unit 31 and the optical amplifier unit 32. The optical splitter unit 31 is configured between the signal separation module 1 and the optical amplifier unit 32. Its multiple input ports are connected to the second service optical signals separated by the multi-channel signal separation module 1. The optical splitter unit 31 first aggregates the multiple second service optical signals into one channel, and then transmits the aggregated second service optical signal to the optical amplifier unit 32 configured on the output side of the optical splitter unit 31. The optical amplifier unit 32 is configured between the second service port b and the optical splitter unit 31. The optical amplifier unit 32 performs unified amplification and compensation processing on the aggregated second service optical signal, and transmits it to the second service port b after processing. The selection of the optical splitter unit 31 needs to match the number of accessed second service optical signals. The amplification power of the optical amplifier unit 32 needs to be matched according to the total loss of the aggregated optical signal to ensure that the power of the amplified optical signal meets the reception requirements of the second service port b.

[0054] The above structure realizes the processing logic of aggregation followed by amplification, providing another feasible solution for processing the second service optical signal. Its advantages are: First, it reduces the number of optical amplification units 32; only one optical amplification unit 32 is needed to achieve amplification and compensation processing of the aggregated second service optical signals, significantly reducing the hardware cost of the equipment. Second, the optical splitting unit 31 aggregates the signals first, and then the optical amplification unit 32 amplifies them uniformly, simplifying the equipment's connection structure and reducing the difficulty of deployment and maintenance. Third, it can adapt to scenarios where the loss of multiple second service optical signals is relatively uniform, achieving an overall improvement in signal power through unified amplification compensation, ensuring transmission quality. Fourth, it complements the previous amplification-following-aggregation solution, allowing for flexible selection of configuration methods based on actual service scenarios (such as signal loss, cost budget, deployment space, etc.), thus expanding the equipment's applicability. Fifth, the unified processing of the aggregated optical signals reduces the number of signal transmission links within the equipment, lowering link loss and interference risks.

[0055] Please refer to Figure 2. The number of optical amplification units 32 is at least one.

[0056] In some embodiments, when a convergence-then-amplification processing scheme is adopted, the number of optical amplification units 32 can be determined according to the amplification requirements of the converged second service optical signal, and at least one optical amplification unit 32 can be configured. For example, in scenarios where the transmission distance is short and the optical signal loss after convergence is small, configuring one optical amplification unit 32 can meet the amplification compensation requirements; in scenarios where the transmission distance is long and the optical signal loss after convergence is large, and a single optical amplification unit 32 cannot meet the amplification requirements, two or more optical amplification units 32 can be configured in series to achieve the required amplification compensation effect through multi-stage amplification; the series connection method of multiple optical amplification units 32 is that the output end of the previous optical amplification unit 32 is connected to the input end of the next optical amplification unit 32, and the converged second service optical signal is sequentially amplified by multiple optical amplification units 32 before finally being transmitted to the second service port b.

[0057] The above structure enables flexible configuration of the number of optical amplification units 32. Its advantages are as follows: First, the configuration of at least one optical amplification unit 32 can adapt to different signal loss scenarios. When the loss is low, the number of optical amplification units 32 can be reduced to control costs; when the loss is high, the number can be increased to ensure amplification effect, improving the flexibility and adaptability of the equipment. Second, the cascaded use of multiple optical amplification units 32 can achieve higher amplification compensation, extending the transmission distance of the second service optical signal and expanding the network coverage. Third, the power of a single optical amplification unit 32 can be selected at a lower specification, achieving high-power amplification through multi-stage cascading, reducing the selection difficulty and cost of a single optical amplification unit 32. Fourth, the multi-stage amplification method allows for segmented control of the optical signal amplification process, avoiding signal distortion caused by a single high-power optical amplification unit 32 and ensuring the transmission quality of the optical signal. Fifth, the configuration of multiple optical amplification units 32 can improve the redundancy of the equipment. When one optical amplification unit 32 fails, the amplification factor of other optical amplification units 32 can be adjusted to temporarily compensate, reducing the risk of service interruption.

[0058] Please continue to refer to Figure 2. The signal processing module 3 is also used to adjust the relative position between the optical splitting unit 31 and the optical amplification unit 32 and the processing order of the second service optical signal according to the transmission direction of the second service port b in the communication link; wherein, the optical splitting unit 31 is configured to perform convergence processing or splitting processing.

[0059] In some embodiments, the transmission direction of the second service port b in the communication link includes an uplink transmission direction (the gateway transmits the second service optical signal to the second service port b) and a downlink transmission direction (the second service port b transmits the second service optical signal to the gateway). The signal processing module 3 can automatically or manually adjust the relative position and processing order of the optical splitting unit 31 and the optical amplification unit 32 according to the different transmission directions, and switch the working mode (convergence or splitting) of the optical splitting unit 31. When it is the uplink transmission direction, the optical splitting unit 31 is configured in convergence mode. At this time, a configuration method of amplification before convergence or convergence before amplification can be adopted to realize the transmission of multiple second service optical signals to the second service port. The optical splitter unit 31 is configured in split mode when the transmission direction is downlink. In this mode, the optical splitter unit 31 has one input port and multiple output ports. The configuration of the optical amplification unit 32 can be adjusted to either the input or output side of the optical splitter unit 31 as needed. For example, the optical amplification unit 32 can first amplify and compensate the second service optical signal output from the second service port b, then transmit it to the optical splitter unit 31 for splitting, and finally transmit the split multiple second service optical signals to the corresponding gateway; or the optical splitter unit 31 can first split the second service optical signal, and then multiple optical amplification units 32 can amplify and compensate the split multiple signals respectively. The switching of the operating mode of the optical splitter unit 31 can be achieved through an internal optical path switching structure, and the adjustment of the processing order can be achieved through a switchable connection interface between modules. The specific transmission direction is not limited.

[0060] Through the above structure, the signal processing module 3 achieves adaptation to bidirectional transmission directions. Its beneficial effects are as follows: First, the signal processing module 3 can flexibly adapt to both uplink and downlink transmission directions, eliminating the need for separate processing modules for different transmission directions, thus reducing equipment costs and network deployment complexity. Second, the switching between aggregation and splitting modes of the optical splitting unit 31 enables the reuse of the same unit in different transmission directions, improving unit utilization. Third, the adjustment of processing order and unit position can be specifically optimized according to the signal characteristics of different transmission directions (such as uplink multi-path aggregation and downlink single-path splitting), ensuring signal quality for bidirectional transmission. Fourth, it adapts to the bidirectional communication requirements of optical communication networks, enabling signal access equipment to fully support uplink high-bandwidth service data upload and downlink high-bandwidth service data distribution, improving the practicality and versatility of the equipment. Fifth, the unified architecture of the signal processing module 3 facilitates subsequent maintenance and upgrades, reducing network operation and maintenance costs.

[0061] Figure 3 shows a schematic diagram of a signal transmission system provided in an embodiment of this disclosure.

[0062] As shown in Figure 3, the signal transmission system includes: an optical line terminal device 11, a signal access device 12, and a gateway 13; wherein, the signal access device 12 includes a signal separation module 1, a transmission module 2, and a signal processing module 3, and the optical line terminal device 11 is provided with at least one first service port a1 and a second service port b.

[0063] In some embodiments, the optical line terminal equipment 11 is a central office device in an optical communication network, deployed in a central equipment room, used to realize signal interaction between the backbone network and the user-side optical network; the gateway 13 is an optical network access device on the user side, including but not limited to optical network units (ONUs) and optical network terminals (ONTs), used to realize the connection between user equipment and the optical network; the first service port a1 and the second service port b are both optical signal interaction ports on the optical line terminal equipment 11, the first service port a1 is an existing port (such as a GPON port or a 10G PON port), and the second service port b is a newly added port adapted to high-bandwidth services (such as a 50G PON port); the signal access device 12 is the signal access device described in the preceding embodiments, and its signal separation module 1, transmission module 2, and signal processing module 3 have the same structure and function as described above, used to realize the separation, transmission, and processing of the first service optical signal and the second service optical signal. The optical line terminal equipment 11, the signal access device 12, and the gateway 13 are connected through optical lines to form a complete signal transmission link.

[0064] Through the above structure, a complete signal transmission system including optical line terminal equipment, signal access equipment, and gateway is constructed. Its beneficial effects are as follows: First, the division of labor among the system components is clear: optical line terminal equipment 11 is responsible for signal interaction, signal access equipment 12 is responsible for signal separation and processing, and gateway 13 is responsible for user-side access, forming a clear signal transmission link and ensuring the orderly operation of the system. Second, the integration of signal access equipment 12 does not require replacing the existing first service port a1 of optical line terminal equipment 11 and gateway 13, making it adaptable to the existing network architecture and reducing the cost and difficulty of system upgrades. Third, the system can simultaneously carry the transmission of first service optical signals and second service optical signals, realizing the parallel operation of existing services and newly added high-bandwidth services, ensuring the continuity and diversity of services. Fourth, the modular system architecture facilitates the individual maintenance and upgrade of each component, improving the system's scalability and ease of operation and maintenance. Fifth, the system is compatible with at least one first service port a1 configuration, and the number of first service ports a1 can be flexibly expanded according to the user scale, improving the system's adaptability.

[0065] The at least one first service port a1 is used to connect to the gateway 13 via the original optical line A, wherein the original optical line A transmits a mixed optical signal containing a first service optical signal and a second service optical signal.

[0066] In some embodiments, each first service port a1 is connected to the corresponding gateway 13 via a primary optical line A. The primary optical line A is an existing fiber optic link deployed in the optical communication network, with one end connected to the first service port a1 of the optical line terminal equipment 11 and the other end connected to the optical interface of the gateway 13. The hybrid optical signal is output by the gateway 13 and includes two types of service optical signals: one type is the first service optical signal adapted to the first service port a1 (such as GPON optical signal and / or 10 GPON optical signal), used to carry basic services; the other type is the second service optical signal (such as 50 GPON optical signal) that needs to be transmitted to the second service port b, used to carry high-bandwidth services (such as 4K / 8K video, cloud gaming, etc.). When the hybrid optical signal is transmitted in the primary optical line A, the two service optical signals use different wavelength channels, which improves the coverage and access range of the service signal.

[0067] Through the above structure, the transmission of the hybrid optical signal in the original optical line A and the connection between the first service port a1 and the gateway 13 are realized. Its beneficial effects are as follows: First, the continued use of the original optical line A ensures the normal transmission of the first service optical signal, avoiding the impact of system upgrades on services and ensuring the continuity of user experience; second, the hybrid optical signal is transmitted in the same original optical line A, eliminating the need to lay a separate link from the gateway 13 to the signal access device 12 for the second service optical signal, reducing link construction costs; third, the use of different wavelength channels ensures the stability of the hybrid optical signal during transmission, avoiding interference between the two service optical signals; fourth, the configuration of at least one first service port a1 allows multiple gateways 13 to access simultaneously, improving the system's user coverage capability; fifth, the hybrid optical signal transmission method allows the gateway 13 to output two service optical signals simultaneously without requiring hardware modifications to the gateway 13, reducing the upgrade costs of user-side equipment.

[0068] The signal separation module 1 is connected to the original optical line A and is used to separate the second service optical signal from the mixed optical signal.

[0069] In some embodiments, the signal separation module 1 is connected in series to the original optical line A, specifically at the link between the first service port a1 and the gateway 13, to achieve real-time separation of the mixed optical signals transmitted in the original optical line A. The signal separation module 1 employs a wavelength identification separation mechanism, internally pre-setting wavelength filtering parameters corresponding to the second service optical signal. When the mixed optical signal passes through the signal separation module 1, the second service optical signal is separated from the mixed optical signal through filtering, while the first service optical signal continues to be transmitted in the original optical line A. For example, when the wavelength of the second service optical signal is 1577nm, the signal separation module 1 sets a 1577nm filtering channel, allowing only the second service optical signal to be separated through this channel, while the first service optical signal (1490nm) continues to be transmitted through the signal separation module 1. The signal separation module 1 is pluggable, facilitating installation and maintenance, and does not affect the transmission characteristics of the original optical line A.

[0070] The above structure enables the separation of mixed optical signals in the original optical line A. Its advantages are as follows: First, the cascaded access of signal separation module 1 achieves real-time separation of mixed optical signals, ensuring timely signal processing and avoiding signal delay. Second, the precise wavelength filtering separation mechanism ensures the purity of the separated second service optical signal, reduces the mixing of the first service optical signal, and guarantees the transmission quality of the two optical signals after separation. Third, the separation process does not affect the normal transmission of the first service optical signal, ensuring service continuity. Fourth, the pluggable access method reduces the installation and maintenance difficulty of signal separation module 1, improving system operation and maintenance efficiency. Fifth, the separation function of signal separation module 1 provides a foundation for the separate processing and transmission of the second service optical signal, enabling high-bandwidth service optical signals to be transmitted and optimized independently of the original optical line A.

[0071] The transmission module 2 is used to transmit at least one first service optical signal separated by the signal separation module 1 to the gateway 13 corresponding to the at least one first service optical signal through the original optical line A, and to transmit the second service optical signal to the gateway 13 corresponding to the second service optical signal through the newly added optical line B.

[0072] In some embodiments, the transmission module 2 has a bidirectional transmission adaptation function. On the one hand, it receives the first service optical signal that has been separated by the signal separation module 1 and continues to be transmitted, and transmits it to the corresponding gateway 13 through the original optical line A, realizing the downlink transmission of the first service optical signal from the optical line terminal equipment 11 to the gateway 13. On the other hand, it receives the first service optical signal output by the gateway 13 and transmits it to the first service port a1 of the optical line terminal equipment 11 through the original optical line A, realizing the uplink transmission of the first service optical signal. For the second service optical signal, the transmission module 2 realizes bidirectional transmission through the addition of an optical line B: in the uplink transmission direction, it receives the second service optical signal output by the gateway 13 separated by the signal separation module 1 and transmits it to the signal processing module 3 through the addition of an optical line B; in the downlink transmission direction, it receives the second service optical signal processed by the signal processing module 3 and transmits it to the corresponding gateway 13 through the addition of an optical line B. The transmission module 2 realizes the transmission guidance of different optical signals on different optical lines through an internal link switching mechanism, ensuring the accuracy of signal transmission.

[0073] Through the above structure, bidirectional split transmission of the first service optical signal and the second service optical signal is realized. Its beneficial effects are as follows: First, the bidirectional transmission function of transmission module 2 adapts to the uplink and downlink transmission requirements of the optical communication network, ensuring bidirectional interaction of service data; second, the split transmission of the two service optical signals on different optical paths eliminates mutual interference, improving the transmission quality and efficiency of both services; third, the original optical line A continues to carry the transmission of the first service optical signal, ensuring the stable operation of existing services, while the newly added optical line B is dedicated to carrying the second service optical signal, ensuring the transmission requirements of high-bandwidth services; fourth, the link switching mechanism of transmission module 2 ensures accurate signal transmission guidance, avoiding signal transmission errors; fifth, it can simultaneously adapt to the transmission of at least one first service optical signal, improving the system's user carrying capacity, while providing a unified transmission channel for the second service optical signal transmission of multiple gateways 13.

[0074] The signal processing module 3 is configured on the newly added optical line B, and is used to receive and process the second service optical signal, and output the processed second service optical signal to the second service port b on the optical line terminal equipment 11.

[0075] In some embodiments, the signal processing module 3 is connected in series on the newly added optical line B. Its input end is connected to the second service optical signal link output by the transmission module 2, and its output end is connected to the second service port b of the optical line terminal equipment 11. The signal processing module 3 performs corresponding processing operations according to the transmission direction and transmission requirements of the second service optical signal: In the uplink transmission direction, it receives multiple second service optical signals transmitted by the transmission module 2, performs convergence processing through the optical splitting unit 31, performs amplification and compensation processing through the optical amplification unit 32, and outputs the processed second service optical signal to the second service port b; In the downlink transmission direction, it receives the second service optical signal output from the second service port b, performs amplification and compensation processing through the optical amplification unit 32, performs splitting processing through the optical splitting unit 31, and outputs the processed multiple second service optical signals to the transmission module 2. The processing parameters of the signal processing module 3 can be dynamically adjusted according to the transmission rate, transmission distance, etc. of the second service optical signal. For example, the amplification factor of the optical amplification unit 32 can be adjusted according to the change in transmission distance to ensure that the quality of the processed signal meets the transmission requirements. It should be noted that the above examples are only illustrative and do not limit the specific requirements.

[0076] Through the above structure, accurate transmission of the second service optical signal to the second service port b is achieved. Its beneficial effects are as follows: First, the processing function of the signal processing module 3 ensures the transmission quality of the second service optical signal, compensates for signal loss in the newly added optical line B, and increases the signal transmission distance; second, uplink aggregation processing enables access of multiple second service optical signals to a single second service port b, improving the resource utilization of the second service port b and reducing the port deployment cost of the optical line terminal equipment 11; third, downlink splitting processing enables signal distribution from a single second service port b to multiple gateways 13, improving the coverage capability of high-bandwidth services; fourth, dynamically adjusted processing parameters allow the signal processing module 3 to adapt to different transmission scenarios, improving the system's flexibility and adaptability; fifth, the signal processing module 3, configured on the newly added optical line B, will not affect the transmission of the original optical line A, ensuring the stable operation of the service.

[0077] The second service port b establishes a communication link with the gateway 13 through the newly added optical line B to transmit the second service optical signal.

[0078] In some embodiments, the second service port b is a high-bandwidth optical signal interaction port on the optical line terminal equipment 11, and its type is adapted to the second service optical signal. For example, when the second service optical signal is a 50G PON optical signal, the second service port b is a 50G PON port. The second service port b establishes a communication link with the gateway 13 through the newly added optical line B. The link establishment process is as follows: the downlink second service optical signal output by the second service port b is processed by the signal processing module 3 and then transmitted to the gateway 13 through the newly added optical line B and the transmission module 2; the uplink second service optical signal output by the gateway 13 is transmitted to the signal processing module 3 through the transmission module 2 and the newly added optical line B, processed, and then transmitted to the second service port b, forming a complete bidirectional communication link. The connection between the newly added optical line B, the second service port b, and the gateway 13 adopts a standard optical interface (such as an SC interface or an LC interface) to ensure the compatibility and stability of the connection.

[0079] Through the above structure, a dedicated communication link is established between the second service port b and gateway 13. Its beneficial effects are as follows: First, the dedicated communication link provides an independent transmission channel for the second service optical signal, ensuring the transmission bandwidth and quality of high-bandwidth services and meeting the needs of high-bandwidth services such as 4K or 8K video and cloud desktops; second, the adoption of standard optical interfaces improves the compatibility and reliability of the link connection, reducing the probability of connection failures; third, the bidirectional transmission capability of the link enables uplink and downlink distribution of high-bandwidth service data, ensuring service integrity; fourth, the establishment of this link does not affect the original optical line A link connection, enabling the parallel operation of the new service link and the existing service link, improving the system's service carrying capacity; fifth, the link can be flexibly deployed according to the distribution of high-bandwidth users, facilitating subsequent service expansion and improving the system's scalability.

[0080] Corresponding to the signal access device described above, this invention also proposes a signal access method. Since the method embodiments of this invention correspond to the device embodiments described above, details not disclosed in the method embodiments can be referred to the device embodiments described above, and will not be repeated here.

[0081] Figure 4 is a schematic flowchart of a signal access method provided in an embodiment of this disclosure.

[0082] As shown in Figure 4, the method includes the following steps: Step 101, the mixed optical signal transmitted in the optical line is separated into different optical optical paths according to the transmission rate by the signal separation module; wherein, the signal separation module is configured on the optical optical path corresponding to at least one target service port.

[0083] In some embodiments, the signal separation module is implemented using an optical separation device with rate identification and wavelength filtering functions, including but not limited to wavelength division multiplexing (WDM) devices, arrayed waveguide gratings (AWG), etc.; the target service port is a port in the optical communication network used to realize optical signal interaction, including but not limited to a Gigabit Passive Optical Network (GPON) port, a 10 Gigabit Passive Optical Network (10G PON) port, etc., at least one target service port is one, two or more target service ports deployed in parallel, adapting to single-port independent processing or multi-port parallel processing scenarios; the optical line is an optical fiber link for transmitting optical signals, and the signal separation module is configured to be deployed in series at the connection node between the target service port and the optical line to ensure that the mixed optical signals transmitted in the optical line can flow completely through the signal separation module; the mixed optical signal is a set of multi-rate service optical signals transmitted synchronously in the same optical line, such as a GPON optical signal with a transmission rate of 1.25Gbps and a 10G optical signal with a transmission rate of 10Gbps. For PON optical signals, the signal separation module uses preset wavelength filtering parameters corresponding to different transmission rates to identify and filter the mixed optical signals, accurately separating the optical signals of different rates into independent service optical signals. For example, a 1.25Gbps GPON optical signal is filtered out through the 1490nm wavelength channel, and a 10Gbps 10GPON optical signal is filtered out through the 1577nm wavelength channel.

[0084] The above method enables precise separation of hybrid optical signals according to transmission rate, with the following advantages: First, the rate-adaptive separation mechanism avoids mutual interference between optical signals of different rates during subsequent transmission, ensuring the original transmission characteristics of various service optical signals. Second, the configuration method of adapting the signal separation module to at least one target service port can flexibly adapt to the deployment needs of optical communication networks of different scales, without the need to design a separate separation scheme for each port. Third, the serial deployment configuration method does not require large-scale modification of the existing optical line topology; only the signal separation module needs to be added at the connection node between the target service port and the optical line, reducing the cost and implementation difficulty of network upgrades. Fourth, the precise separation effect provides a foundation for the differentiated transmission of optical signals of different rates, ensuring that various service optical signals can be processed according to their own transmission requirements.

[0085] Step 102: The different service optical signals are transmitted through their respective optical lines via the transmission module.

[0086] In some embodiments, the transmission module is implemented using an optical transmission device with multi-channel optical signal forwarding function, including but not limited to an optical splitter, which is equipped with an optical interface adapted to the transmission parameters of optical signals of different rates, and can realize the directional forwarding of various types of service optical signals after separation; the corresponding optical lines are optical fiber links adapted to the transmission rate and bandwidth requirements of each type of service optical signal; the operation process of the transmission module is as follows: after receiving the multiple independent service optical signals obtained by separation, the transmission rate parameters of each signal are matched through the internal signal identification unit, and then the service optical signals of different rates are directionally forwarded to the corresponding optical line interface through the channel switching mechanism, so as to realize the independent transmission of different service optical signals in their respective dedicated optical lines.

[0087] The above method enables independent transmission of optical signals for services at different rates. Its advantages are as follows: First, the dedicated optical line configuration ensures independent transmission resources for various service optical signals, avoiding bandwidth contention caused by shared transmission links and guaranteeing the transmission bandwidth and quality of high-speed service optical signals. Second, the multi-channel adaptation function of the transmission module is compatible with various rates of service optical signals, improving the method's versatility and adaptability. Third, the split transmission method allows for independent monitoring and maintenance of the transmission status of various service optical signals. When a transmission failure occurs in one optical signal, only the corresponding optical line needs to be checked, without affecting the normal transmission of other service optical signals, thus improving network operation and maintenance efficiency. Fourth, the corresponding optical line type can be flexibly selected according to the transmission distance requirements of different service optical signals, extending the effective transmission distance of service optical signals and expanding the coverage of the optical communication network.

[0088] In summary, the signal access method provided in this disclosure includes: separating a mixed optical signal transmitted in an optical line into different service optical signals according to the transmission rate using a signal separation module; wherein the signal separation module is configured on the optical line corresponding to at least one target service port; transmitting the different service optical signals through their respective corresponding optical lines using a transmission module; separating the mixed optical signals in the optical line according to the transmission rate using the signal separation module, and then transmitting the different service optical signals separately using the transmission module, can not only effectively avoid transmission interference between signals of different rates and ensure the stability and reliability of the transmission of various service optical signals, but also adapt the configuration of the optical line of at least one target service port to the signal separation module, so as to realize the independent processing of signals of different rates in multi-port scenarios without large-scale modification of existing optical lines, significantly reducing deployment costs and improving the adaptability of equipment.
