Technical Field

[0001] This application relates to the field of optical communication technology, and in particular to an optical communication terminal device and an energy-saving control method for the optical communication terminal device. Background Technology

[0002] In rapidly developing optical communication application scenarios such as IoT terminals, 5G fronthaul networks, fiber-to-the-room (FTTR), and industrial optical interconnection, optical communication terminal equipment has shown technical characteristics of strong service bursts, obvious transmission intermittency, and strict power consumption constraints.

[0003] To adapt to dynamically changing communication loads and link states, existing optical communication terminals generally adopt power management strategies based on fixed thresholds or simple state machines, triggering module-level power on / off based on single communication parameters such as data throughput and link connection status; unified power supply or coarse-grained partitioned power supply methods, with functional units such as optical transmitters, optical receivers, and signal processors sharing a power supply domain or only performing simple group control; and power mode switching is triggered by instantaneous state parameters.

[0044] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0046] In rapidly developing optical communication applications such as IoT terminals, 5G fronthaul networks, Fiber to the Room (FTTR), and industrial optical interconnection, optical communication terminal equipment exhibits technical characteristics such as strong service bursts, significant transmission intermittency, and stringent power consumption constraints. To adapt to dynamically changing communication loads and link states, existing optical communication terminals generally adopt power management strategies based on fixed thresholds or simple state machines, triggering module-level power on / off based on single communication parameters such as data throughput and link connection status; unified power supply or coarse-grained partitioned power supply methods, with functional units such as optical transmitters, receivers, and signal processors sharing a power domain or only undergoing simple group control; and power mode switching triggered by instantaneous state parameters. However, existing optical communication terminals struggle to simultaneously achieve the dual goals of low-power operation and real-time performance, failing to meet the usage requirements of high-efficiency, high-reliability, and low-latency optical communication terminals in scenarios such as IoT, 5G access, and home optical interconnection.

[0047] In view of the above-mentioned technical problems, this application provides an optical communication terminal device, and the following embodiments will specifically describe the optical communication terminal device.

[0048] In one exemplary embodiment, such as Figure 1 As shown, an optical communication terminal device 1 is provided, including: a data acquisition unit 11, a power supply unit 12, and a power consumption coordination control unit 13; the power consumption coordination control unit 13 is connected to the data acquisition unit 11 and the power supply unit 12 respectively; the power supply unit 12 is connected to the data acquisition unit 11.

[0049] Data acquisition unit 11 is used to acquire multi-dimensional state parameters based on optical signals; the multi-dimensional state parameters include communication service load intensity, channel transmission quality, and link connection activity; data acquisition unit 11 includes multiple functional units. Channel transmission quality may include at least one of signal-to-noise ratio and bit error rate.

[0050] The power consumption co-control unit 13 is used to determine the target power consumption mode of the power supply unit 12 based on multi-dimensional state parameters. In some embodiments, the power consumption co-control unit 13 adopts a 40nm process application-specific integrated circuit (ASIC), which integrates a state fusion calculation module, a load trend prediction hardware accelerator, and a multi-channel power management coprocessor. It can perform parameter weighted fusion, mode determination, load prediction, pre-start control, and smooth adjustment. The ASIC receives data uploaded by the data acquisition unit 11, and hardware acceleration completes the fusion calculation, mode determination, predictive inference, and power supply control signal output without the need for an external processor. The ASIC significantly improves the control response speed, reduces the power consumption of the control module itself, shrinks the hardware size, and improves the terminal integration and working stability, making it suitable for mass production applications. It has short control latency, extremely low static power consumption, and high computing efficiency, and can complete state determination and instruction output in the nanosecond to microsecond range. In practical applications, other processes and integration schemes can be selected according to requirements, and this application embodiment does not limit this.

[0051] The power supply unit 12 is used to adjust the power supply voltage, power supply current, and on / off state of each functional unit in the data acquisition unit 11 based on the target power consumption mode. The power supply unit 12 can supply power to the functional units in the data acquisition unit 11, and can also supply power to the wake-up circuit in the terminal device. There can be one or more power supply units 12. When there is only one power supply unit 12, it can be configured with multiple electrically isolated power supply units to supply power to the functional units of the data acquisition unit 11. When there are multiple power supply units 12, each power supply unit 12 can independently supply power to the functional units of the data acquisition unit 11 and the wake-up circuit.

[0052] In the embodiments of this application, the first functional unit of the data acquisition unit 11 amplifies the electrical signal output by the electrical terminal device and outputs an optical signal. Simultaneously, it converts the optical signal transmitted through the optical fiber into a weak electrical signal and outputs it. The second functional unit processes the weak electrical signal, including amplification, equalization, clock recovery, and error detection, to ensure signal quality. The third functional unit acquires multi-dimensional state parameters during the optical signal conversion process and outputs them to the power consumption coordination control unit 13. The acquisition period of the data acquisition unit 11 can be set according to actual scenario requirements, for example, 10ms. In some embodiments, the power consumption coordination control unit 13 can perform weighted fusion calculations on the received multi-dimensional state parameters and determine the target power consumption mode of the power supply unit 12 based on the mapping relationship between the calculation results and the power consumption mode.

[0053] In some embodiments, the power consumption cooperative control unit 13 has a preset power consumption pattern recognition model, which is trained from training samples consisting of historical communication state parameters labeled with power consumption patterns. After receiving the multi-dimensional state parameters, the power consumption cooperative control unit 13 inputs the multi-dimensional state parameters into the power consumption pattern recognition model for detection to obtain the target power consumption pattern of the power supply unit 12.

[0054] In some embodiments, the power requirements of the functional units and wake-up circuit of the data acquisition unit 11 are different under different power consumption modes. The power consumption coordination control unit 13 can determine the power consumption mode of the next moment in real time based on the multi-dimensional state parameters collected in real time, and send the corresponding control command to the power supply unit 12 according to the target power consumption mode. The power supply unit 12 provides differentiated power supply to the functional units and wake-up circuit based on the control command, so as to realize the dynamic switching of the functional units and wake-up circuit of the data acquisition unit 11 between multiple power consumption modes such as full speed, light load, standby, and sleep.

[0055] The aforementioned optical communication terminal equipment significantly improves the accuracy and robustness of power consumption decisions by collecting multi-dimensional state parameters, effectively avoiding erroneous switching and frequent start-stop problems caused by single-parameter judgment. Furthermore, it controls the power supply unit 12 based on the target power consumption mode, achieving differentiated power supply and energy efficiency regulation for functional units, enabling the optical communication terminal equipment to maintain optimal energy efficiency under different service loads. This application significantly reduces the average power consumption of the entire optical communication terminal, improves the energy efficiency utilization of hardware resources, and simultaneously meets the requirements for low-latency and high-reliability communication in dynamic service scenarios.

[0056] In one exemplary embodiment, such as Figure 2 As shown, the power supply unit 12 includes multiple electrically isolated power supply domains 121, and each functional unit of the data acquisition unit 11 is connected to a power supply domain 121.

[0057] Power supply domain 121 is used to independently regulate the connected functional units. Power supply domain 121 can power DC-DC converters, such as TPS62260, TPS62130, ADP2114, LTC3636, etc., supplying power to each functional unit in the data acquisition unit 11, independently regulating the output voltage, current, and on / off state. Each power supply domain 121 is isolated from the others by a ferrite bead and a 0Ω resistor to suppress crosstalk. The power supply unit 12 also includes an enable control switch for activating power supply domain 121.

[0058] In the embodiments of this application, the power supply unit 12 can continuously output voltage within a preset voltage range, which can be from 0.8V to 3.3V. That is, the DC-DC converter of the power supply unit 12, in conjunction with an external digital-to-analog converter module, adjusts the reference voltage at the feedback terminal through a pulse width modulation signal, continuously adjusting the output voltage in small steps within the range of 0.8V to 3.3V. This results in high voltage regulation linearity and low ripple, matching the operating voltage requirements of data acquisition functional units (such as optical signal transceiver units and signal processing units) under different power consumption modes. The power consumption coordination control unit 13 outputs control commands according to the target power consumption mode, and each power supply domain 121 of the power supply unit 12 adjusts the output voltage to the target value corresponding to the target power consumption mode according to the control commands, providing suitable power supply voltages for each functional unit of the data acquisition unit 11 and the wake-up circuit.

[0059] Existing optical communication terminal power supply units have low adjustment precision and limited range, failing to meet the voltage requirements of different functional units in different modes, thus limiting the scope for energy efficiency optimization. The aforementioned device provides differentiated power supply to functional units through multiple power supply domains 121 in the power supply unit 12, thereby meeting the voltage requirements of functional units in different modes.

[0060] In one exemplary embodiment, such as Figure 3 As shown, the functional units of the data acquisition unit 11 include an optical signal transceiver unit 111, a signal processing unit 112, and a communication status sensing unit 113; the optical signal transceiver unit 111 is connected to the signal processing unit 112; the signal processing unit 112 is connected to the communication status sensing unit 113; the optical signal transceiver unit 111, the signal processing unit 112, and the communication status sensing unit 113 are respectively connected to the power supply unit 12;

[0061] The optical transceiver unit 111 is used to receive optical signals and convert them into electrical signals. The optical transceiver unit 111 can be an integrated optical transceiver module, incorporating an 850nm VCSEL laser and a PIN photodiode. Its package size is 12.7mm × 9.3mm × 3.4mm. The TX port is connected to the signal processing unit 112 via a 50Ω microstrip line, and the RX port is connected to the signal processing unit 112 via a transimpedance amplifier. It supports dynamic adjustment of transmit power to adapt to different power consumption modes. It features low jitter and high sensitivity. In practical applications, other models can also be selected, such as OPF2012 or CXP-SR10; this embodiment does not limit the specific model.

[0062] The signal processing unit 112 is used to modulate and demodulate the electrical signal to obtain the processed electrical signal. The signal processing unit 112 can be a SoC chip, with the ARM core responsible for protocol processing and the programmable logic part implementing modulation and demodulation, forward error correction and bit error detection. It supports dynamic frequency scaling and can adjust the working clock frequency according to the power consumption mode to reduce dynamic power consumption. In practical applications, other models can also be selected for this component, such as Intel Cyclone V FPGA chip or NXP i.MX8 SoC chip. This application embodiment does not limit this.

[0063] The communication status sensing unit 113 is used to collect multi-dimensional status parameters during the signal conversion and processing in real time. The communication status sensing unit 113 can be configured with three parallel acquisition channels to collect service load throughput, channel signal-to-noise ratio and bit error rate, and link connection status, respectively. All data are uploaded synchronously via the SPI bus. The acquisition frequency meets the real-time judgment requirements, and the acquisition frequency is not less than 100Hz to ensure the real-time performance and accuracy of the status data.

[0064] In the embodiments of this application, the optical signal transceiver unit 111 of the data acquisition unit 11 amplifies the electrical signal output by the electrical terminal equipment and outputs an optical signal. Simultaneously, it converts the optical signal transmitted from the optical fiber into a weak electrical signal and outputs it. The signal processing unit 112 processes the weak electrical signal, including amplification, equalization, clock recovery, and bit error detection, to ensure signal quality. The communication status sensing unit 113 reads the signal-to-noise ratio (SNR) data through the built-in register of the RF transceiver chip and calculates the bit error rate (BER) using the internal hardware counter of the signal processing unit 112. The SNR and BER are acquired synchronously at a frequency not lower than 100Hz to ensure timestamp alignment. The two data streams are packaged and uploaded to the power consumption co-control unit 13 via the SPI bus. Either parameter or combination can be used individually. In some embodiments, the power consumption co-control unit 13 can perform weighted fusion calculations on the received multi-dimensional status parameters and determine the target power consumption mode of the power supply unit 12 based on the mapping relationship between the calculation results and the power consumption mode.

[0065] Existing optical communication terminals only use received optical power to characterize channel quality, which cannot reflect the true transmission reliability. Low acquisition frequency leads to delayed state determination, easily causing erroneous handovers. The communication state sensing unit 113 of this application acquires signal-to-noise ratio (SNR) or bit error rate (BER) data in real time, quickly feeding back changes in link transmission quality and providing accurate channel state input to the power consumption co-control unit 13. Using SNR and BER can accurately reflect link transmission reliability; high-frequency synchronous acquisition shortens state response time, reduces the probability of false judgments of channel degradation, and minimizes invalid wake-ups and unnecessary power handovers.

[0066] In one exemplary embodiment, the power consumption coordination control unit 13 is specifically used for:

[0067] The comprehensive state judgment result is determined based on multi-dimensional state parameters; and the target power consumption mode corresponding to the comprehensive state judgment result is determined based on the mapping relationship between the comprehensive state and the power consumption mode; the power consumption modes include full-speed mode, light-load mode, standby mode and sleep mode.

[0068] Differentiated power supply control signals are output to the power supply unit 12 according to the target power consumption mode.

[0069] In the embodiments of this application, after receiving the multi-dimensional state parameters, the power consumption collaborative control unit 13 normalizes the multi-dimensional state parameters and then performs a weighted summation to obtain a comprehensive state determination result. The weights of each state parameter can be set according to the actual scenario requirements and are not limited here. For example, the weight ranges for each dimension of the state parameter can be set as follows: data load intensity weight is 0.35-0.45, channel transmission quality weight is 0.30-0.40, and link connection activity weight is 0.20-0.30. When performing the weighted summation, values ​​can be randomly selected from the weight ranges of each dimension of the state parameter. For example, the weights of each dimension of the state parameter can be 0.4, 0.35, and 0.25, respectively.

[0070] In some embodiments, the mapping relationship between the overall state and the power consumption mode can be as follows: the overall state range corresponding to the full-speed mode is [0.75, 1.0], the overall state range corresponding to the light-load mode is [0.45, 0.74], the overall state range corresponding to the standby mode is [0.15, 0.44], and the overall state range corresponding to the sleep mode is [0, 0.14].

[0071] In some embodiments, the power consumption co-control unit 13 compares the calculated comprehensive state determination result with the comprehensive state range in the mapping relationship between comprehensive state and power consumption mode. If the comprehensive state determination result is within a certain comprehensive state range, the power consumption mode corresponding to the comprehensive state range is taken as the target power consumption mode.

[0072] In some embodiments, the power consumption coordination control unit 13 generates differentiated power supply control commands based on the target power consumption mode. When the target power consumption mode is full-speed mode, the power supply control command can be a full-voltage, full-frequency command, for example, the optical signal transceiver unit transmits at a power of -1dBm, the signal processing unit clock frequency is 667MHz, and all DC-DC converters operate at full load.

[0073] In some embodiments, when the target power consumption mode is a light-load mode, the power supply control command can be: the transmit power of the optical transceiver unit and the operating clock frequency of the signal processing unit are both reduced by a preset ratio. After entering the light-load mode, the power consumption coordination control unit 13 adjusts the laser drive current and bias current of the optical transceiver unit to reduce the transmit power to a preset ratio of the full-speed mode; at the same time, it configures the clock phase-locked loop of the signal processing unit to reduce the operating clock frequency to a preset ratio of the full-speed mode, reducing the computational load while ensuring transmission reliability. The optical transceiver unit maintains link connectivity with a lower transmit power, and the signal processing unit completes signal processing with a lower clock frequency, meeting the bandwidth requirements of medium-load services. This maximizes the reduction of power consumption under light-load conditions while ensuring basic communication capabilities, balancing communication quality and energy saving, and is suitable for medium-load service scenarios such as home broadband and video-on-demand.

[0074] In some embodiments, when the target power consumption mode is standby mode, the power supply control command can be: the optical signal transceiver unit shuts down the transmit drive circuit, leaving only the receive monitoring circuit operational. In standby mode, the power consumption coordination control unit 13 shuts down the laser drive circuit of the optical signal transceiver unit, stopping optical signal transmission; simultaneously, it maintains the bias voltage supply to the photodetector, activates the low-power monitoring circuit, and controls the static current of the monitoring circuit to an extremely low level, retaining only the link signal detection capability. The complete power-off of the transmit circuit reduces the power consumption on the transmit side, while the receive monitoring circuit maintains low-power operation, continuously monitoring whether a wake-up signal exists on the link. Shutting down the transmit path significantly reduces standby power consumption, while retaining low-power monitoring ensures rapid response to sudden service interruptions, balancing ultra-low standby power consumption with real-time wake-up capability.

[0075] In some embodiments, when the target power consumption mode is sleep mode, the power supply control command can be: only the wake-up timer and interrupt detection circuits are kept running. In sleep mode, the power consumption co-control unit 13 shuts off the power supply path of all functional units, providing power only to the wake-up timer, ultra-low power real-time clock, and interrupt detection circuit. All other modules are powered down, reducing the overall static power consumption to the nanowatt level. Except for the wake-up and interrupt detection circuits, all hardware stops working and waits for a timed wake-up or an external interrupt signal to trigger the wake-up process. Minimizing the retained operating circuits achieves extremely low power sleep mode, significantly extending the battery life of the battery-powered terminal and meeting the needs of long-term maintenance-free scenarios such as smart meters and passive IoT nodes.

[0076] In one exemplary embodiment, such as Figure 4 As shown, the power consumption coordination control unit 13 also includes a smooth transition unit 131;

[0077] The smooth transition unit 131 is used to gradually adjust the power supply voltage or operating clock frequency in fixed steps and time intervals during mode switching of the functional unit based on the power supply control signal. The smooth transition unit can be a dedicated timing control state machine.

[0078] In the embodiments of this application, in response to power supply control commands, the power consumption coordination control unit adjusts the power supply voltage or operating clock frequency of the power supply unit 12 step by step according to a set step interval and amplitude, gradually approaching the target value until the mode switching is completed. For example, the voltage or clock adjustment step interval of each power supply domain of the control power supply unit 12 is not less than 100μs, the single adjustment amplitude does not exceed a fixed proportion of the target set value, and the adjustment process is monitored in a closed loop throughout to ensure that the parameters rise or fall smoothly and avoid sudden shocks.

[0079] Existing optical communication terminals use hard switching for power consumption modes. Sudden changes in power supply voltage or clock frequency can cause power rail collapse and increased clock jitter, leading to increased bit error rate and even link lockout. The above method, by setting a smooth transition unit 131, enables the power supply unit 12 to gradually adjust the functional units, effectively avoiding voltage disturbances and clock jitter, controlling the bit error rate fluctuation during the switching process to an extremely low range, ensuring stable data throughput, and achieving a smooth, disturbance-free transition.

[0080] In one exemplary embodiment, the power consumption coordination control unit 13 is further specifically used for:

[0081] Collect historical status data and determine load trends based on the historical status data; historical status data includes operating voltage, ambient temperature, communication load, and optical signal strength;

[0082] Perform a pre-start operation on data acquisition device 11 based on load trends.

[0083] In the embodiments of this application, the optical communication terminal equipment is further equipped with a load status collector. The load status collector collects multi-dimensional load status parameters (i.e., historical status data) according to a preset sampling period and stores them in an on-chip FIFO memory. The collected multi-dimensional load status parameters are transmitted to the power consumption co-control unit 13. The power consumption co-control unit 13 can, on the one hand, select historical multi-dimensional load status parameters for continuous sampling periods from the multi-dimensional load status parameters, and calculate a weighted moving average of the historical multi-dimensional load status parameters based on a preset sliding time window statistical prediction model to obtain the short-term load trend. On the other hand, it can also randomly extract historical multi-dimensional load status parameters for continuous sampling periods or interval sampling periods, and use the extracted parameter sequence as input based on a preset long short-term memory network time series prediction sub-model to obtain the long-term load trend, i.e., the probability distribution of communication load in the future multiple periods.

[0084] In some embodiments, the power consumption coordination control unit 13 analyzes the determined load trend and maintains the current operating mode of the functional unit when the load trend is decreasing. When the load trend is increasing, a pre-start control signal is sent to the functional unit and the wake-up circuit of the data acquisition unit 11 to start the functional unit and the wake-up circuit in advance.

[0085] Existing load prediction methods for optical communication terminals are simple, unable to adapt to sudden service disruptions, have low prediction accuracy, unreliable pre-start triggering, and struggle to eliminate service unavailability windows. The aforementioned device, by implementing a dual load trend prediction structure, significantly improves load prediction accuracy, reduces false triggering rates, ensures critical modules complete pre-starting before service arrival, and completely eliminates the service interruption window during the switch from low-power mode to full-speed mode.

[0086] In one exemplary embodiment, the load trend includes short-term load trends and long-term load trends. The power consumption co-control unit 13 is further specifically used for:

[0087] The short-term load trend is obtained by calculating the moving average of the communication load.

[0088] Long-term load trends are obtained by predicting historical state data based on time series models.

[0089] In the embodiments of this application, after the collected multidimensional load state parameters are transmitted to the power consumption collaborative control unit 13, the power consumption collaborative control unit 13 can, on the one hand, filter historical multidimensional load state parameters for continuous sampling periods from the multidimensional load state parameters, and filter the communication load parameter from the historical multidimensional load state parameters. Based on a preset sliding time window statistical prediction model, a weighted moving average is calculated on the communication load to obtain the short-term load trend. On the other hand, it can also randomly extract historical multidimensional load state parameters for continuous sampling periods or interval sampling periods, and based on a preset long short-term memory network time series prediction sub-model, use the extracted parameter sequence as input to obtain the long-term load trend, that is, the probability distribution of communication load in the future multiple periods.

[0090] In one exemplary embodiment, such as Figure 5 As shown, the power consumption coordination control unit 13 also includes a pre-start control unit 132; the pre-start control unit 132 is used to control the functional units under the corresponding trend to perform pre-start operations when the short-term load trend or the long-term load trend is an upward trend.

[0091] In the embodiments of this application, the power consumption coordination control unit 13 analyzes the determined load trend. When the load trend is upward, it sends a pre-start control signal to the functional unit and wake-up circuit of the data acquisition unit 11 to start the functional unit and wake-up circuit in advance.

[0092] By introducing load trend prediction and key module pre-start mechanism, the above-mentioned equipment can restore circuit driving capability in advance before the communication load increases, significantly reduce the wake-up delay from low power mode to full speed mode, eliminate the service unavailability window under sudden business, and reduce the risk of data loss and communication interruption.

[0093] In one exemplary embodiment, the optical communication terminal device based on any of the foregoing embodiments further provides an energy-saving control method for the optical communication terminal device, such as... Figure 6 As shown, the method includes:

[0094] S601 is based on optical signal acquisition of multi-dimensional state parameters.

[0095] Among them, the multidimensional state parameters include communication service load intensity, channel transmission quality, and link connection activity.

[0096] In the embodiments of this application, the optical signal transceiver unit of the data acquisition unit amplifies the electrical signal output from the electrical terminal equipment and outputs an optical signal. Simultaneously, it converts the optical signal transmitted from the optical fiber into a weak electrical signal and outputs it. The signal processing unit processes the weak electrical signal, including amplification, equalization, clock recovery, and bit error detection, to obtain the processed signal. The communication status sensing unit reads the signal-to-noise ratio (SNR) data through the built-in register of the RF transceiver chip and calculates the bit error rate (BER) using the internal hardware counter of the signal processing unit. The SNR and BER are acquired synchronously at a frequency of not less than 100Hz. The two data streams are packaged and uploaded to the power consumption co-control unit via the SPI bus.

[0097] S602 determines the target power consumption mode of the power supply unit based on multi-dimensional state parameters.

[0098] In the embodiments of this application, after receiving the multi-dimensional state parameters, the power consumption collaborative control unit normalizes the multi-dimensional state parameters and then performs a weighted summation to obtain a comprehensive state determination result. The weights of each state parameter can be set according to the actual scenario requirements and are not limited here. For example, the weight ranges for each dimension of the state parameter can be set as follows: data load intensity 0.35-0.45, channel transmission quality 0.30-0.40, and link connection activity 0.20-0.30. When performing the weighted summation, values ​​can be randomly selected from the weight ranges of each dimension of the state parameter. For example, the weights of each dimension of the state parameter can be 0.4, 0.35, and 0.25, respectively.

[0099] In some embodiments, the mapping relationship between the overall state and the power consumption mode can be as follows: the overall state range corresponding to the full-speed mode is [0.75, 1.0], the overall state range corresponding to the light-load mode is [0.45, 0.74], the overall state range corresponding to the standby mode is [0.15, 0.44], and the overall state range corresponding to the sleep mode is [0, 0.14].

[0100] In some embodiments, the power consumption co-control unit compares the calculated comprehensive state determination result with the comprehensive state range in the mapping relationship between comprehensive state and power consumption mode. If the comprehensive state determination result is within a certain comprehensive state range, the power consumption mode corresponding to the comprehensive state range is taken as the target power consumption mode.

[0101] S603 adjusts the power supply voltage, power supply current, and on / off status of each functional unit in the data acquisition unit based on the target power consumption mode.

[0102] In the embodiments of this application, the power consumption collaborative control unit generates differentiated power supply control commands based on the target power consumption mode. When the target power consumption mode is full-speed mode, the power supply control command can be a full-voltage, full-frequency command. For example, the optical signal transceiver unit transmits power at -1dBm, the signal processing unit clock frequency is 667MHz, and all DC-DC converters operate at full load.

[0103] In some embodiments, when the target power consumption mode is light-load mode, the power supply control command can be: the transmit power of the optical transceiver unit and the operating clock frequency of the signal processing unit are both reduced by a preset ratio. After entering light-load mode, the power consumption coordination control unit adjusts the laser drive current and bias current of the optical transceiver unit to reduce the transmit power to a preset ratio of the full-speed mode; at the same time, it configures the clock phase-locked loop of the signal processing unit to reduce the operating clock frequency to a preset ratio of the full-speed mode, reducing the computational load while ensuring transmission reliability. The optical transceiver unit maintains link connectivity with lower transmit power, and the signal processing unit completes signal processing with a lower clock frequency, meeting the bandwidth requirements of medium-load services. This maximizes the reduction of power consumption under light-load conditions while ensuring basic communication capabilities, balancing communication quality and energy saving, and is suitable for medium-load service scenarios such as home broadband and video-on-demand.

[0104] In some embodiments, when the target power consumption mode is standby mode, the power supply control command can be: the optical transceiver unit shuts down the transmit drive circuit, leaving only the receive monitoring circuit operational. In standby mode, the power consumption coordination control unit shuts down the laser drive circuit of the optical transceiver unit, stopping optical signal transmission; simultaneously, it maintains the bias voltage supply to the photodetector, activates the low-power monitoring circuit, and controls the static current of the monitoring circuit to an extremely low level, retaining only the link signal detection capability. The transmit circuit is completely powered off to reduce transmit-side power consumption, while the receive monitoring circuit maintains low-power operation, continuously monitoring for the presence of a wake-up signal on the link. Shutting down the transmit path significantly reduces standby power consumption, while retaining low-power monitoring ensures rapid response to sudden service interruptions, balancing ultra-low standby power consumption with real-time wake-up capability.

[0105] In some embodiments, when the target power consumption mode is sleep mode, the power supply control command can be: only the wake-up timer and interrupt detection circuits are kept running. In sleep mode, the power consumption co-control unit shuts off the power supply path of all functional units, providing power only to the wake-up timer, ultra-low power real-time clock, and interrupt detection circuit. All other modules are powered down, reducing the overall static power consumption to the nanowatt level. Except for the wake-up and interrupt detection circuits, all hardware stops working and waits for a timed wake-up or an external interrupt signal to trigger the wake-up process. Minimizing the retained operating circuits achieves extremely low power sleep mode, significantly extending the battery life of the battery-powered terminal and meeting the needs of long-term maintenance-free scenarios such as smart meters and passive IoT nodes.

[0106] The aforementioned method integrates three heterogeneous state parameters—service load intensity, channel transmission quality, and link connection activity—to construct a multi-dimensional collaborative state awareness mechanism. This significantly improves the accuracy and robustness of power consumption decisions, effectively avoiding erroneous handovers and frequent start-stops caused by single-parameter judgments. Combined with a four-level refined power consumption state model and a multi-level electrically isolated power supply architecture, it enables differentiated power supply and energy efficiency control for functional units such as optical signal transceiver, signal processing, and state awareness, ensuring optimal energy efficiency under varying service loads. This method can significantly reduce the average power consumption of the entire optical communication terminal, improve the energy efficiency utilization of hardware resources, and simultaneously meet the requirements for low-latency and high-reliability communication in dynamic service scenarios.

[0107] In an exemplary embodiment, the above-described S602 "determines the target power consumption mode of the power supply unit based on multi-dimensional state parameters", such as Figure 7 As shown, it includes:

[0108] S701 determines the comprehensive state judgment result based on multi-dimensional state parameters.

[0109] In the embodiments of this application, after receiving the multi-dimensional state parameters, the power consumption collaborative control unit normalizes the multi-dimensional state parameters and then performs a weighted summation to obtain a comprehensive state determination result. The weights of each state parameter can be set according to the actual scenario requirements and are not limited here. For example, the weight ranges for each dimension of the state parameter can be set as follows: data load intensity 0.35-0.45, channel transmission quality 0.30-0.40, and link connection activity 0.20-0.30. When performing the weighted summation, values ​​can be randomly selected from the weight ranges of each dimension of the state parameter. For example, the weights of each dimension of the state parameter can be 0.4, 0.35, and 0.25, respectively.

[0110] S702 determines the target power consumption mode based on the mapping relationship between the overall state and the power consumption mode.

[0111] The power consumption modes include full-speed mode, light-load mode, standby mode, and sleep mode. The mapping relationship between the overall state and the power consumption mode can be as follows: the overall state range corresponding to full-speed mode is [0.75, 1.0], the overall state range corresponding to light-load mode is [0.45, 0.74], the overall state range corresponding to standby mode is [0.15, 0.44], and the overall state range corresponding to sleep mode is [0, 0.14].

[0112] In the embodiments of this application, the power consumption cooperative control unit compares the calculated comprehensive state determination result with the comprehensive state range in the mapping relationship between comprehensive state and power consumption mode. If the comprehensive state determination result is within a certain comprehensive state range, the power consumption mode corresponding to the comprehensive state range is taken as the target power consumption mode.
