Description

Technical Field

[0001] The present invention relates to the field of communication technology, and in particular to a photoelectric transceiver device and a photoelectric transceiver method. Background Art

[0002] In the field of communication technology, with the continuous improvement of data transmission rate, the application of active optical cables is becoming more and more extensive. In the application process, there is a widespread demand for switching between the transmitter and the receiver of high-speed electrical signal ports. For example, the Type-C connector can support USB4 standard mode and DP Alternate Mode. The Type-C connector contains 4 pairs of differential high-speed pins. In standard mode, the high-speed pins are two transmit and two receive, while in DP Alternate Mode, the high-speed pins need to be reused and configured as four transmit or four receive. Therefore, the high-speed pin direction switching function of the active cable is an important technology to realize the full-function Type-C connector.

[0003] At present, in the optoelectronic transceiver commonly used in the industry, the switching between the transmitting end and the receiving end is usually controlled by a switch composed of a transmission gate, for example, the switch can be a double-pole single-throw switch or a double-pole double-throw switch. By controlling the opening and closing of the switch, the electrical port is switched between the transmitting end and the receiving end.

[0004] However, these switches usually have large parasitic capacitance and certain series impedance, which often affect the quality of signal transmission when using switches to switch the transmitter and receiver of electrical ports. As the signal rate increases from 10Gbps per channel of USB3.2 to 20Gbps of USB4, high-speed performance has been challenged even more. Summary of the invention

[0026] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0027] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0028] The present application provides an optoelectronic transceiver and an optoelectronic transceiver method, wherein an amplifying module is connected to an electrical port through a first type of driving module, and a laser driving module is connected to the electrical port through a second type of driving module. Compared with the method of using a switch connection, while realizing full-duplex transmission in a switchable direction, the influence of parasitic capacitance and series impedance can be significantly reduced, thereby improving the quality of signal transmission. In addition, it can also help to optimize impedance matching and avoid the problems of poor impedance matching and reduced swing of the electrical interface caused by the use of a switch connection. Among them, the switchable direction means that the electrical port can be switched to a transmitting end or a receiving end, so that the high-speed pin can be switched to a transmitting end or a receiving end, that is, the high-speed pin can switch the transmitting and receiving direction.

[0029] The optoelectronic transceiver device involved in the present application may be an integrated circuit structure. The integrated circuit structure may be arranged on a chip or a circuit board. The circuit board may be a PCBA (Printed Circuit Board Assembly), which is a printed circuit board with components assembled.

[0030] The optoelectronic transceiver provided by the present application will be described in detail below with reference to the accompanying drawings.

[0031] See also Figure 1 , Figure 1 Schematic diagram of the structure of the optoelectronic transceiver provided in the embodiment of the present application. Figure 1 As shown, in some embodiments, the optoelectronic transceiver device 1 includes: a first type driving module 11 , a second type driving module 12 , an electrical port 21 , an amplifying module 22 and a laser driving module 23 .

[0032] See also Figure 2 , Figure 2 1 is a schematic diagram of the port circuit structure of the first embodiment of the optoelectronic transceiver provided in the embodiment of the present application. Figure 2 As shown, in some embodiments, the amplification module 22 is used to be electrically connected to the optical signal receiving module 31, the laser driving module 23 is used to be electrically connected to the optical signal transmitting module 32, and the electrical port 21 is used to be electrically connected to the amplification module 22 or the laser driving module 23.

[0033] Optionally, the electrical port 21 is connected to a resistor R1 and a resistor R2. The resistor R1 and the resistor R2 serve as terminating resistors of the electrical port 21, and are used to optimize impedance matching, thereby reducing reflection of electrical signals.

[0034] In some implementations, the impedance of the termination resistor may be determined according to a standard corresponding to the application, thereby achieving impedance matching. In this way, the reflection of the electrical signal in the electrical channel can be reduced, thereby improving the quality of signal transmission.

[0035] Optionally, the laser driving module 23 is connected to the resistor R3 and the resistor R4 . The resistor R3 and the resistor R4 serve as the output load of the second type driving module 12 .

[0036] It is understandable that the optoelectronic transceiver device also includes other circuit structures, such as a control module, so that the optoelectronic transceiver device can work normally. Figure 2 Not shown.

[0037] Optionally, the first type of driving module may be a driver, for example, the first type of driving module may be an output stage driver. The second type of driving module may be a driver, for example, the second type of driving module may be an input stage driver.

[0038] In some embodiments, the circuits of the first type of driving module and the second type of driving module are the same as the circuits of the basic driving module. The basic driving module includes a current source, two triodes or field effect transistors, an electrical signal input terminal, an electrical signal output terminal, a first control voltage input terminal and a second control voltage input terminal. The electrical signal input terminal is used to input an electrical signal encoded with information. The electrical signal output terminal is used to output an electrical signal encoded with information. The first control voltage input terminal is used to input a first control voltage. The second control voltage input terminal is used to input a second control voltage. The first control voltage and the second control voltage are used to control the opening and closing of the basic driving module. The first end and the second end of the first control voltage input terminal are both used to input the first control voltage. The first end and the second end of the second control voltage input terminal are both used to input the second control voltage.

[0039] Optionally, the first control voltage input terminal includes two transistors or field effect transistors, and the second control voltage input terminal includes two transistors or field effect transistors.

[0040] See also Figure 3 , Figure 3 Schematic diagram of the circuit structure of the basic driving module provided in the embodiment of the present application. Figure 3As shown, exemplarily, the basic driving module 10 includes a first field effect transistor M1 and a second field effect transistor M2. The drains of the first field effect transistor M1 and the second field effect transistor M2 are both floating, and the sources are both connected to the ground through a current source. The gate of the first field effect transistor M1 is connected or disconnected with the first end of the electrical signal input terminal, and the voltage value of the first end of the electrical signal input terminal is voltage U1+. The gate of the second field effect transistor M2 is connected or disconnected with the second end of the electrical signal input terminal, and the voltage value of the second end of the electrical signal input terminal is voltage U1-.

[0041] Optionally, both the first field effect transistor M1 and the second field effect transistor M2 are N-type MOS transistors.

[0042] Optionally, the first end of the first control voltage input terminal controls a transistor or a field effect transistor to connect or disconnect the first end of the electrical signal input terminal and the gate of the first field effect transistor, and the second end of the first control voltage input terminal controls a transistor or a field effect transistor to connect or disconnect the second end of the electrical signal input terminal and the gate of the second field effect transistor.

[0043] Optionally, the first end of the second control voltage input terminal controls a transistor or a field effect transistor to connect or disconnect the power supply and the gate of the first field effect transistor, and the second end of the second control voltage input terminal controls a transistor or a field effect transistor to connect or disconnect the power supply and the gate of the second field effect transistor.

[0044] like Figure 3 As shown, exemplarily, the first end of the first control voltage input terminal connects or disconnects the first end of the electric signal input terminal and the gate of the first field effect tube M1 by controlling the third field effect tube M3, and the second end of the first control voltage input terminal connects or disconnects the second end of the electric signal input terminal and the gate of the second field effect tube M2 by controlling the fourth field effect tube M4. The first end of the second control voltage input terminal connects or disconnects the power supply and the gate of the first field effect tube M1 by controlling the fifth field effect tube M5, and the second end of the second control voltage input terminal connects or disconnects the power supply and the gate of the second field effect tube M2 by controlling the sixth field effect tube M6.

[0045] Optionally, the third field effect transistor M3 , the fourth field effect transistor M4 , the fifth field effect transistor M5 and the sixth field effect transistor M6 are all P-type MOS transistors.

[0046] In some embodiments, the polarity of the first control voltage and the second control voltage are opposite. When the first control voltage is a low potential voltage and the second control voltage is a high potential voltage, the circuit from the electric signal input terminal to the electric signal output terminal is connected, the basic driving module is turned on, the electric signal is input from the electric signal input terminal, and is output from the electric signal output terminal. When the first control voltage is a high potential voltage and the second control voltage is a low potential voltage, the circuit from the electric signal input terminal to the electric signal output terminal is not connected, the basic driving module is turned off, and the electric signal cannot be output from the electric signal output terminal.

[0047] Specifically, when the first control voltage is a low potential voltage, and the second control voltage is a high potential voltage, the third field effect transistor M3 and the fourth field effect transistor M4 are turned on, so that the circuit from the electric signal input end to the electric signal output end is turned on, the basic driving module is turned on, and the electric signal is input from the electric signal input end and output from the electric signal output end. When the first control voltage is a high potential voltage, and the second control voltage is a low potential voltage, the third field effect transistor M3 and the fourth field effect transistor M4 are turned off, the circuit from the electric signal input end to the gate of the first field effect transistor M1 and the second field effect transistor M2 is high resistance, the path of the electric signal input is cut off, the basic driving module is turned off, and the electric signal cannot be output from the electric signal output end.

[0048] The first control voltage input terminal and the second control voltage input terminal are used to control the conduction and cutoff of two transistors or field effect tubes. Compared with the existing setting method of using switches to form a voltage-limited circuit, there is no need to consider the size of the switch resistance. Because the switch resistance will increase the load voltage drop and compress the working voltage range of the field effect tube, the method of the present application will not compress the working voltage range of the field effect tube, and the performance of the field effect tube can be guaranteed to be unaffected. In addition, compared with the existing setting method of using switches to form an impedance matching limited circuit, there is no need to reduce the load resistance to solve the impedance matching problem. Because if the load resistance is reduced to solve the impedance matching problem, the output swing will be reduced at the same time (the output swing is the output current multiplied by the load resistance), so the method of the present application will not reduce the output swing, which can help optimize the impedance matching and avoid the problems of poor impedance matching and swing reduction of the electrical interface caused by the use of switch connection.

[0049] In addition, switches composed of transmission gates (such as double-pole single-throw switches or double-pole double-throw switches) usually have large parasitic capacitance and series impedance. The basic driver module provided by the present application does not include switches composed of transmission gates. While achieving full-duplex transmission with switchable directions, it can significantly reduce the influence of parasitic capacitance and series impedance, thereby improving the quality of signal transmission. As described above, in some embodiments, the circuits of the first type of driver module and the second type of driver module are the same as the circuits of the basic driver module, but are connected differently to the circuits of other modules.

[0050] Optionally, the electric signal input end of the first type of driving module is connected to the amplification module, and the electric signal output end is connected to the electrical port. The electric signal input end of the second type of driving module is connected to the electrical port, and the electric signal output end is connected to the laser driving module.

[0051] In some embodiments, the amplification module may be an amplifier, for example, the amplification module may be a transimpedance amplifier, and the transimpedance amplifier is used to convert a current signal into a voltage signal.

[0052] Optionally, the laser driving module may be a laser driver, and the laser driver is used to drive the optical signal transmitting module.

[0053] Optionally, one electrical port corresponds to one transmission channel.

[0054] In some embodiments, the amplification module is connected to the electrical port via a first type of driving module, and the laser driving module is connected to the electrical port via a second type of driving module.

[0055] Optionally, an amplifier module is connected to at least one electrical port via a first type of driver module, and a laser driver module is connected to at least one electrical port via a second type of driver module. An electrical port is connected to at least one amplifier module via a first type of driver module, and to at least one laser driver module via a second type of driver module.

[0056] like Figure 2 As shown, in some embodiments, an amplification module 22 is connected to an electrical port 21 through a first type of driving module 11, and a laser driving module 23 is connected to an electrical port 21 through a second type of driving module 12. In this way, the electrical port can be switched to a state of being connected to the amplification module or the laser driving module at any time, and the transmission channel corresponding to the electrical port can be switched to a sending channel or a receiving channel at any time, thereby meeting the needs of signal transmission.

[0057] In some embodiments, when the first type driving module 11 is turned on, the electrical port 21 is electrically connected to the amplifying module 22 , so that the electrical port 21 sends the electrical signal obtained by the optical signal receiving module 31 by converting the optical signal.

[0058] In some embodiments, when the second type driving module 12 is turned on and the first type driving module 11 is turned off, the electrical port 21 is electrically connected to the laser driving module 23 to drive the optical signal transmitting module 32 to convert the electrical signal into an optical signal via the electrical signal received by the electrical port 21 .

[0059] In some embodiments, when the first type driving module 11 is turned on, the second type driving module 12 is controlled to be turned off. In this way, when the first type driving module is turned on, the optical signal transmitting module can be prevented from sending an erroneous signal.

[0060] like Figure 2 As shown, in some embodiments, an electrical port 21, an amplification module 22, a laser driving module 23, a first type driving module 11 and a second type driving module 12 constitute a signal transceiver unit A.

[0061] Optionally, the signal transceiver unit A further includes a resistor R1, a resistor R2, a resistor R3 and a resistor R4.

[0062] Optionally, the optoelectronic transceiver device may include a plurality of electrical ports, an amplification module, a laser driving module, a first type of driving module and a second type of driving module. Figure 2 The composition and circuit structure of the signal transceiver unit shown in the figure, multiple signal transceiver units are set.

[0063] See also Figure 4 , Figure 4 1 is a schematic diagram of the port circuit structure of the second embodiment of the optoelectronic transceiver provided in the embodiment of the present application. Figure 4 As shown, in some embodiments, an amplification module 22 is connected to multiple electrical ports 21 through multiple first-type driving modules 11, and a laser driving module 23 is connected to multiple electrical ports 21 through multiple second-type driving modules 12. In this way, while achieving full-duplex transmission with switchable directions, the number of hardware modules can be reduced, thereby reducing hardware costs.

[0064] It is understandable that the optoelectronic transceiver also includes other circuit structures to enable the optoelectronic transceiver to work normally. Figure 4 Not shown.

[0065] like Figure 4 As shown, preferably, two electrical ports 21, two first-type driving modules 11, two second-type driving modules 12, an amplifying module 22 and a laser driving module 23 constitute a signal transceiver unit A. In the signal transceiver unit A, the amplifying module 22 is connected to an electrical port 211 through a first-type driving module 111, the amplifying module 22 is connected to another electrical port 212 through a first-type driving module 112, the laser driving module 23 is connected to an electrical port 211 through a second-type driving module 121, and the laser driving module 23 is connected to another electrical port 212 through a second-type driving module 122. In this way, full-duplex transmission with switchable direction can be achieved, and the number of hardware modules can be reduced.

[0066] Optionally, the electrical port 212 is connected to a resistor R5 and a resistor R6 , and the resistor R5 and the resistor R6 serve as terminating resistors of the electrical port 212 .

[0067] Optionally, when the optoelectronic transceiver device includes a plurality of electrical ports, an amplifying module, a laser driving module, a first type of driving module and a second type of driving module, Figure 4 The composition and circuit structure of the signal transceiver unit shown in the figure, multiple signal transceiver units are set.

[0068] In some embodiments, in the signal transceiver unit, when the first type of driving module connected to one electrical port is turned on, the second type of driving module connected to another electrical port is turned on. That is, when one electrical port sends an electrical signal obtained by converting an optical signal into an optical signal by an optical signal receiving module, the other electrical port drives the optical signal transmitting module to convert the electrical signal into an optical signal through the received electrical signal. In this way, the amplification module and the laser driving module in the signal transceiver unit can be kept working, and then the optical signal receiving module and the optical signal transmitting module can be kept working, so that all the optical signal receiving modules and the optical signal transmitting modules can be fully utilized for signal transmission, thereby improving the efficiency of signal transmission.

[0069] like Figure 4 As shown, exemplarily, in the signal transceiver unit A, when the first type driver module 111 connected to the electrical port 211 is turned on, the second type driver module 122 connected to the electrical port 212 is also turned on. When the first type driver module 112 connected to the electrical port 212 is turned on, the second type driver module 121 connected to the electrical port 211 is also turned on.

[0070] See also Figure 5 , Figure 5 Schematic diagram of the circuit structure of the optoelectronic transceiver provided in the embodiment of the present application in the application scenario. Figure 5 As shown, in some embodiments, an electrical port of the optoelectronic transceiver 1 is connected to an electrical port corresponding to the connector on the PCBA 70 through a metal lead. For example, the electrical port 211 is connected to the electrical port 71 of the connector through the metal lead 60, and the electrical port 212 is connected to the electrical port 72 of the connector through the metal lead 60.

[0071] Optionally, the electrical ports of the optoelectronic transceiver 1 are all on-chip metal pad electrical ports, and the electrical ports of the connector are all PCB metal pad electrical ports. On the connector, one electrical port is connected to a group of metal pins through a transmission line. For example, electrical port 71 is connected to metal pin 73 through a transmission line, and electrical port 72 is connected to metal pin 74 through a transmission line.

[0072] In some embodiments, PCBA 70 is used to be inserted into electronic device 80. Electronic device 80 includes a connector for inserting PCBA 70, and the connector of electronic device 80 is provided with metal pins for correspondingly electrically connecting with metal pins on PCBA 70. For example, metal pin 81 is used to be electrically connected with metal pin 73, and metal pin 82 is used to be electrically connected with metal pin 74.

[0073] Optionally, the electronic device includes a computer, a mobile phone, etc.

[0074] Optionally, the metal pin 81 is a metal pin for a receiving electrical port, and the metal pin 82 is a metal pin for a transmitting electrical port. When the electrical port 211 sends an electrical signal obtained by converting an optical signal into an electrical signal by the optical signal receiving module, the electrical signal is sequentially transmitted to the electronic device 80 through the electrical port 71, the metal pin 73, and the metal pin 81, so that the electronic device 80 can receive the information carried by the electrical signal. When the electronic device 80 sends an electrical signal, the electrical signal is sequentially transmitted to the electrical port 212 through the metal pin 82, the metal pin 74, and the electrical port 72, and the electrical signal received by the electrical port 212 drives the optical signal transmitting module 32 to convert the electrical signal into an optical signal, so that the electronic device 80 can send the information carried by the electrical signal.

Figure 6 As shown, the present application also provides an optoelectronic transceiver system 2, which includes a first optoelectronic transceiver 1A, an optical cable B and a second optoelectronic transceiver 1B. The first optoelectronic transceiver 1A is connected to the second optoelectronic transceiver 1B via the optical cable B.

[0076] In some embodiments, an interface of the optoelectronic transceiver device integrates a signal transceiver unit.

[0077] In some embodiments, each connector of the optical cable is integrated with an optical signal receiving module and an optical signal transmitting module, so the optical cable can achieve full-duplex signal transmission with switchable direction.

[0078] In some embodiments, when the first connector of the optical cable is connected to the first interface of the first optoelectronic transceiver device and the second connector of the optical cable is connected to the second interface of the second optoelectronic transceiver device, the optical signal is transmitted through the optical cable.

[0079] Specifically, when an optical signal is sent from the first optoelectronic transceiver to the second optoelectronic transceiver, the second type of driver module in the first interface is turned on and the first type of driver module is turned off, so that the electrical signal received by the electrical port drives the optical signal transmitting module to convert the electrical signal into an optical signal, and the first type of driver module in the second interface is turned on, so that the electrical port sends the electrical signal obtained by the optical signal receiving module converting the optical signal, thereby realizing the transmission of the optical signal through the optical cable. At this time, a signal transceiver unit realizes full-duplex signal transmission with switchable direction by connecting to an optical cable.

[0124] See also Figure 8 , Figure 8 FIG. 1 is a schematic diagram of a partial port circuit structure of the third implementation mode of the optoelectronic transceiver provided in the embodiment of the present application. Figure 8 As shown, in some embodiments, a decoding module 41 is connected to multiple electrical ports 21 through multiple fourth-type driving modules 13. Figure 8 In some embodiments, a coding module is connected to multiple electrical ports through multiple third-type driving modules.

[0125] Optionally, a decoding module is also connected to an electrical port, and the electrical port is used to connect to a corresponding electrical port on the PCBA.

[0126] It is understandable that although Figure 8 For the sake of simplicity, only the circuit configuration of the decoding module is shown in FIG. 1 , but an encoding module can also be connected to multiple electrical ports through multiple third-type driving modules. Figure 8 In addition, an encoding module is also connected to an electrical port, which is used to connect to a corresponding electrical port on the PCBA.

[0127] In some embodiments, an electrical port is connected to multiple encoding modules through a third type of driver module, and is connected to multiple decoding modules through a fourth type of driver module. In this way, the electrical port can switch the connected encoding module or decoding module. When the encoding modes corresponding to at least two encoding modules are different, and the decoding modes corresponding to at least two decoding modules are different, the transmission channel corresponding to the electrical port can switch the encoding mode and the decoding mode, and send or receive signals in conjunction with the above-mentioned channel switching mode, thereby meeting the needs of signal transmission and improving the security of signal transmission.

[0128] In some embodiments, two electrical ports, four third-class driver modules, four fourth-class driver modules, two decoding modules and two encoding modules constitute a signal encoding and decoding unit. In the signal encoding and decoding unit, the first encoding module is connected to an electrical port through a third-class driver module, the first encoding module is connected to another electrical port through a third-class driver module, the second encoding module is connected to an electrical port through a third-class driver module, and the second encoding module is connected to another electrical port through a third-class driver module.

[0131] In some implementations, the control module is further used to determine the target coding mode of the electrical port, and then determine the target coding module corresponding to the electrical port according to the target coding mode. For specific determination methods, please refer to step S140 of the optoelectronic transceiver method.

[0132] Optionally, when an electrical port is connected to only one encoding module, the target encoding module corresponding to the electrical port is the encoding module connected to the electrical port.

[0134] In some embodiments, when the second type driver module connected to the electrical port is turned on, the control module is further used to control all third type driver modules connected to the target encoding module except the target third type driver module to be turned off.

[0142] See also Fig. 9 , Fig. 9 is a flow chart of the optoelectronic transceiver method provided in the embodiment of the present application. Fig. 9 As shown, the optoelectronic transceiver method includes: step S100 to step S200.

[0143] Step S100: when a first control signal is received, the first type driving module is controlled to start, so that the electrical port is electrically connected to the amplifying module, and the electrical port sends an electrical signal obtained by converting the optical signal into an electrical signal by the optical signal receiving module.

[0144] Step S200: When a second control signal is received, the second type driving module is controlled to be turned on and the first type driving module is controlled to be turned off, so as to drive the optical signal transmitting module through the electrical signal received by the electrical port to convert the electrical signal into an optical signal.

[0145] In some implementations, the control module is used to execute step S100 and step S200.

[0146] In some embodiments, when the control module of the first optoelectronic transceiver device wants to control the first type of driver module or the second type of driver module to turn on or off, it first sends an opening notification message or a closing notification message to the second optoelectronic transceiver device connected to the first optoelectronic transceiver device through an optical cable, so that when the first type of driver module corresponding to a channel of the first optoelectronic transceiver device is turned on, the control module of the second optoelectronic transceiver device controls the second type of driver module corresponding to the channel to turn on; when the second type of driver module corresponding to a channel of the first optoelectronic transceiver device is turned on, the control module of the second optoelectronic transceiver device controls the first type of driver module corresponding to the channel to turn on.

[0147] In some embodiments, when the control module of the second optoelectronic transceiver receives the start notification information of the first type of driver module corresponding to a channel of the first optoelectronic transceiver, the second type of driver module corresponding to the channel is controlled to be turned on. When the control module of the second optoelectronic transceiver receives the start notification information of the second type of driver module corresponding to a channel of the first optoelectronic transceiver, the first type of driver module corresponding to the channel is controlled to be turned on.

[0148] In some embodiments, when the control module of the second optoelectronic transceiver receives shutdown notification information of a first type of driver module corresponding to a channel of the first optoelectronic transceiver, the second type of driver module corresponding to the channel is controlled to be shut down. When the control module of the second optoelectronic transceiver receives shutdown notification information of a second type of driver module corresponding to a channel of the first optoelectronic transceiver, the first type of driver module corresponding to the channel is controlled to be shut down.

[0149] In some embodiments, when the control module of the first optoelectronic transceiver device wants to control the third type of driver module or the fourth type of driver module to turn on or off, it first sends an opening notification message or a closing notification message to the second optoelectronic transceiver device connected to the first optoelectronic transceiver device through an optical cable, so that when the third type of driver module corresponding to a channel of the first optoelectronic transceiver device is turned on, the control module of the second optoelectronic transceiver device controls the fourth type of driver module corresponding to the channel to turn on; when the fourth type of driver module corresponding to a channel of the first optoelectronic transceiver device is turned on, the control module of the second optoelectronic transceiver device controls the third type of driver module corresponding to the channel to turn on.

[0150] In some embodiments, when the control module of the second optoelectronic transceiver receives the start notification information of the third type of driver module corresponding to a channel of the first optoelectronic transceiver, the fourth type of driver module corresponding to the channel is controlled to be turned on. When the control module of the second optoelectronic transceiver receives the start notification information of the fourth type of driver module corresponding to a channel of the first optoelectronic transceiver, the third type of driver module corresponding to the channel is controlled to be turned on.

[0151] In some embodiments, when the control module of the second optoelectronic transceiver receives shutdown notification information of the third type of driver module corresponding to a channel of the first optoelectronic transceiver, the fourth type of driver module corresponding to the channel is controlled to be shut down. When the control module of the second optoelectronic transceiver receives shutdown notification information of the fourth type of driver module corresponding to a channel of the first optoelectronic transceiver, the third type of driver module corresponding to the channel is controlled to be shut down.

[0152] In some embodiments, the control module is used to determine whether the electrical port needs to send an electrical signal obtained by converting an optical signal into an optical signal by the optical signal receiving module, or whether the electrical signal received by the electrical port needs to drive the optical signal transmitting module to convert the electrical signal into an optical signal. In this case, the method further includes: step S101 to step S102.

[0153] Step S101: Acquire data type information of a transmission channel corresponding to each electrical port.

[0154] In some implementations, the data type information may include an upload data type, a download data type, and an interaction data type.

[0155] Optionally, the download data type includes sub-download data types such as a live broadcast data type and a file download data type, the upload data type includes sub-upload data types such as a file upload data type, and the interaction data type further includes sub-interaction data types such as a video data type and a voice data type.

[0156] In some embodiments, when the type of data to be sent or received by the electrical port changes, the data type information of the transmission channel corresponding to the electrical port will also change accordingly. Therefore, step S101 is performed once every first preset time interval, and then the subsequent steps are performed again.

[0157] Step S102: judging whether the electrical port needs to send an electrical signal obtained by converting an optical signal into an optical signal by an optical signal receiving module, or needs to drive an optical signal transmitting module to convert an electrical signal into an optical signal by using an electrical signal received by the electrical port according to the data type information corresponding to the electrical port.

[0158] In some implementations, when the data type information corresponding to the electrical port is an upload data type, it is determined that the electrical port needs to drive the optical signal transmitting module to convert the electrical signal into an optical signal through the electrical signal received by the electrical port. When the data type information corresponding to the electrical port is a download data type, it is determined that the electrical port needs to send the electrical signal obtained by converting the optical signal into an optical signal by the optical signal receiving module.

[0159] Optionally, when the data type information corresponding to the electrical port is an interactive data type, it is determined that the electrical port needs to switch direction within a time period, that is, it is necessary to send the optical signal receiving module to convert the optical signal into an electrical signal, and it is also necessary to drive the optical signal transmitting module to convert the electrical signal into an optical signal through the electrical signal received by the electrical port. At this time, it is first determined that the electrical port needs to send the optical signal receiving module to convert the optical signal into an electrical signal, and subsequently, it is determined whether the electrical port needs to switch direction at any time according to the received transmission request information.

[0160] Optionally, the transmission request information includes sending request information and receiving request information. When sending request information is received through the electrical port, it is determined that the electrical port needs to send an electrical signal obtained by converting an optical signal into an electrical signal by the optical signal receiving module. When receiving request information is received through the electrical port, it is determined that the electrical signal received through the electrical port drives the optical signal transmitting module to convert the electrical signal into an optical signal.

[0161] An amplifier module or a laser driver module can only be used by one electrical port. When an amplifier module is connected to multiple electrical ports, and / or a laser driver module is connected to multiple electrical ports, the signal transmission requirements of some electrical ports may not be met. Figure 4 As shown, for example, when the electrical port 211 drives the laser driving module 23 through the received electrical signal, and then drives the optical signal transmitting module 32 to convert the electrical signal into an optical signal to send the electrical signal, the electrical port 212 cannot drive the laser driving module 23 through the received electrical signal, and the transmission channel corresponding to the electrical port 212 cannot send information. Therefore, in order to improve the efficiency of signal transmission, it is necessary to schedule the use rights of the amplification module and / or the laser driving module.

[0162] In some implementations, step S100 includes steps S110 to S130.

[0163] Step S110: Acquire first connection relationship information between each electrical port and the amplification module.

[0164] Herein, defining that the electrical port is connected to the amplifying module via the first type of driving module is equivalent to connecting the electrical port to the amplifying module.

[0165] Step S120: When the control module receives the first control signal or determines that the electrical port needs to send the electrical signal obtained by converting the optical signal into the electrical signal by the optical signal receiving module, the target amplification module corresponding to the electrical port is determined according to the first connection relationship information.

[0166] In some implementations, when it is determined according to the first connection relationship information that the electrical port is connected to only one amplification module through the first type of driving module, the amplification module is determined as the target amplification module.

[0167] In some embodiments, when it is determined according to the first connection relationship information that the electrical port is connected to a plurality of amplification modules, the amplification module usage status information is obtained, and the target amplification module corresponding to the electrical port is determined from the plurality of amplification modules according to the first connection relationship information and the amplification module usage status information. Specifically, a plurality of amplification modules connectable to the electrical port are determined according to the first connection relationship information, and an amplification module is selected from the plurality of amplification modules according to the amplification module usage status information as the target amplification module corresponding to the electrical port.

[0168] Optionally, when it is determined according to the amplification module usage status information that there is at least one idle amplification module among the multiple amplification modules, an idle amplification module is selected as a target amplification module corresponding to the electrical port.

[0169] In some implementations, the target amplification module is determined according to data type information of a transmission channel corresponding to each electrical port.

[0170] In some embodiments, a weight corresponding to each electrical port is calculated based on data type information of a transmission channel corresponding to each electrical port, and based on the weight corresponding to the electrical port electrically connected to each amplification module, an amplification module electrically connected to an electrical port having a smaller weight than the current electrical port is selected from multiple amplification modules as a target amplification module corresponding to the current electrical port.

[0171] In some embodiments, when there is no amplification module electrically connected to an electrical port with a smaller weight than the current electrical port among multiple amplification modules, the sending demand of the current electrical port is added to a first demand queuing list, and at regular intervals, a search is performed for an amplification module electrically connected to an electrical port with a smaller weight than the current electrical port or an idle amplification module based on the first connection relationship information and the amplification module usage status information. When the search is successful, the currently found amplification module is used as the target amplification module corresponding to the current electrical port, and the sending demand of the current electrical port is deleted from the first demand queuing list, otherwise the search continues.

[0172] In some embodiments, the initial weight corresponding to each electrical port is calculated based on the data type information of the transmission channel corresponding to each electrical port. Each data type information corresponds to a preset first parameter value. For example, the upload data type, the download data type, and the interaction data type correspond to different first parameter values.

[0173] Optionally, the first parameter value of the interactive data type is greater than the first parameter value of the download data type, because the interactive data type often contains more information.

[0174] Optionally, the first parameter value of the download data type is greater than the first parameter value of the upload data type, because the information of the download data type often has a larger amount of information.

[0175] In some implementations, each sub-download data type corresponds to a preset second parameter value. For example, for the interactive data type, the video data type and the voice data type correspond to different second parameter values ​​respectively.

[0176] Optionally, the second parameter value of the video data type is greater than the second parameter value of the voice data type, because the information of the video data type often has a larger amount of information.

[0177] Optionally, an initial calculation formula for the weight corresponding to the electrical port is: Initial weight value = a×b+c.

[0178] Wherein, a represents the first parameter value corresponding to the data type information of the electrical port, b represents the second parameter value corresponding to the data type information of the electrical port, and c represents the static factor corresponding to the electrical port, which is a preset value.

[0179] In some embodiments, a static factor is pre-set for each electrical port according to the purpose of the electrical port in the circuit. For example, if the electrical port is an electrical port connected to a sensor, the signal transmission requirement is to transmit the collected data once every certain period of time, and the amount of data is small, a smaller static factor is set accordingly. If the electrical port is connected to a data processing unit, a large amount of processed data needs to be transmitted to the electronic device irregularly, a larger static factor is set accordingly.

[0180] In some implementations, the weight corresponding to each electrical port is updated and calculated based on the amount of information sent or received by each electrical port in real time. In this way, the weight corresponding to the electrical port can reflect the actual usage of the electrical port.

[0181] Optionally, each data type information corresponds to a reference information amount.

[0182] Optionally, the update calculation formula of the weight corresponding to the electrical port is: Updated weight value = initial weight value + d × (real-time information volume of the electrical port / reference information volume corresponding to the data type information of the electrical port).

[0183] The real-time information volume of the electrical port is the information volume sent or received by the electrical port in real time. d represents the adjustment factor, which is a preset value.

[0184] In some implementations, the target amplification module is newly determined for each electrical port every second preset time interval.

[0185] Optionally, when re-determining the target amplification module, the weight corresponding to the electrical port is recalculated using an update calculation formula for the weight corresponding to the electrical port, and then the target amplification module is re-determined for each electrical port according to the method described above.

[0186] In some implementations, the weights corresponding to the electrical ports may not be updated, thereby reducing the amount of calculation.

[0187] In some embodiments, when a signal transceiver unit includes multiple electrical ports, the multiple electrical ports in the signal transceiver unit can use the amplification module in turn, and the duration of each use of the amplification module is the second preset time interval. At this time, the target amplification module corresponding to the current electrical port is determined according to the order in which the electrical ports use the amplification modules in turn.

[0188] Step S130: a target first-type driving module connected to the target amplifying module and the electrical port is turned on according to the control of the target amplifying module, so that the electrical port is electrically connected to the target amplifying module, and the electrical port sends the electrical signal obtained by converting the optical signal into the electrical signal by the optical signal receiving module.

[0189] In some implementations, the use time of each amplification module can be predicted based on the data type information, historical transmission information volume, real-time information volume, and historical transmission duration of each electrical port, and the target first-class driving module corresponding to the electrical port can be controlled to remain turned on during the use time. That is, the electrical port can always use the corresponding target amplification module during the use time without switching the target amplification module.

[0190] Optionally, multiple model characteristic parameters are calculated based on data type information, historical transmission information volume, real-time information volume and historical transmission duration, and a prediction equation is constructed based on the multiple model characteristic parameters, and then the prediction equation is used to predict the usage time of the amplification module.

[0191] In some embodiments, the plurality of model characteristic parameters include average transmission time, standard deviation of transmission volume, weight corresponding to data type information, and real-time information volume, etc. The average transmission time is the average value of a plurality of historical transmission time. The standard deviation of transmission volume is the standard deviation of the historical transmission information volume.

[0192] In some embodiments, a linear regression method is used to construct a prediction equation.

[0193] Optionally, the prediction equation is: Usage time = β0 + β1 × average transmission time + β2 × standard deviation of transmission volume + β3 × weight corresponding to data type information + β4 × real-time information volume + … + ε.

[0194] Among them, β0 represents the intercept, β1, β2, β3 and β4 represent the coefficients of each model characteristic parameter, and ε represents the error term.

[0195] Optionally, an artificial intelligence model is used to predict the usage time of the electrical port based on data type information, real-time information volume, historical transmission time points, and historical transmission durations.

[0196] In some embodiments, step S100 also includes: monitoring the usage status of the amplifying module electrically connected to each electrical port, and when it is determined that the target amplifying module is damaged based on the usage status of the target amplifying module electrically connected to the electrical port, selecting an amplifying module from multiple amplifying modules connected to the electrical port as the target amplifying module, and executing step S130.

[0197] In some embodiments, after step S130, in the signal transceiver unit, when one electrical port is controlled to switch to be electrically connected to the amplification module first, it is determined that another electrical port needs to drive the optical signal transmission module to convert the electrical signal into an optical signal through the received electrical signal.

[0198] Optionally, when another electrical port also needs to send the electrical signal obtained by converting the optical signal into an electrical signal by the optical signal receiving module, and the weight corresponding to the other electrical port is greater than the weight corresponding to the current electrical port, it is determined that an electrical port needs to continue to be electrically connected to the corresponding target amplification module, and the sending demand of the current electrical port is added to the first demand queue list, and then the amplification module electrically connected to the electrical port with a smaller weight than the current electrical port or the idle amplification module is searched once every period of time according to the first connection relationship information and the amplification module usage status information. When the search is successful, the currently found amplification module is used as the target amplification module corresponding to the current electrical port, and the sending demand of the current electrical port is deleted from the first demand queue list, otherwise the search continues.

[0199] In some implementations, step S200 includes steps S210 to S230.

[0200] Step S210: obtaining second connection relationship information between each electrical port and the laser driving module.

[0201] Herein, defining that the electrical port is connected to the laser driving module through the second type driving module is equivalent to connecting the electrical port to the laser driving module.

[0202] In some implementations, step S110 and step S210 may be performed simultaneously.

[0203] Step S220: When the control module receives the second control signal or determines that the electrical signal received through the electrical port needs to drive the optical signal transmitting module to convert the electrical signal into an optical signal, the target laser driving module corresponding to the electrical port is determined according to the second connection relationship information.

[0204] In some implementations, when it is determined according to the second connection relationship information that the electrical port is connected to only one laser driving module through the second type driving module, the laser driving module is determined as the target laser driving module.

[0205] In some embodiments, when it is determined according to the second connection relationship information that the electrical port is connected to a plurality of laser driving modules, the laser driving module use status information is obtained, and the target laser driving module corresponding to the electrical port is determined from the plurality of laser driving modules according to the second connection relationship information and the laser driving module use status information. Specifically, a plurality of laser driving modules connectable to the electrical port is determined according to the second connection relationship information, and a laser driving module is selected from the plurality of laser driving modules according to the laser driving module use status information as the target laser driving module corresponding to the electrical port.

[0206] The method of determining the target laser driving module refers to the method of determining the target amplifying module in step S120.

[0207] Optionally, when it is determined according to the laser driving module usage status information that there is at least one idle laser driving module among the multiple laser driving modules, an idle laser driving module is selected as a target laser driving module corresponding to the electrical port.

[0208] In some implementations, the target laser driving module is determined according to data type information of a transmission channel corresponding to each electrical port.

[0209] In some embodiments, a weight corresponding to each electrical port is calculated based on data type information of a transmission channel corresponding to each electrical port, and a laser driving module electrically connected to an electrical port having a smaller weight than the current electrical port is selected from a plurality of laser driving modules according to the weight corresponding to the electrical port electrically connected to each laser driving module as a target laser driving module corresponding to the current electrical port.

[0210] Optionally, when there is no laser driving module electrically connected to an electrical port with a smaller weight than the current electrical port among the multiple laser driving modules, the driving demand of the current electrical port is added to the second demand queuing list, and a laser driving module electrically connected to an electrical port with a smaller weight than the current electrical port or an idle laser driving module is searched once at regular intervals according to the second connection relationship information and the laser driving module usage status information. When the search is successful, the currently found laser driving module is used as the target laser driving module corresponding to the current electrical port, and the driving demand of the current electrical port is deleted from the second demand queuing list, otherwise the search continues.

[0211] In some implementations, the initial weight corresponding to each electrical port is calculated according to the data type information of the transmission channel corresponding to each electrical port. The calculation method is as described in step S120.

[0212] In some implementations, the weight corresponding to each electrical port is updated and calculated according to the amount of information sent or received by each electrical port in real time. The calculation method is as described in step S120.

[0213] In some embodiments, when a signal transceiver unit includes multiple electrical ports, the multiple electrical ports in the signal transceiver unit can use the laser driving module in turn, and the duration of each use of the laser driving module is the second preset time interval. At this time, the target laser driving module corresponding to the current electrical port is determined according to the order in which the electrical ports use the laser driving modules in turn.

[0214] Step S230: According to the target laser driving module, a target second-type driving module connected to the target laser driving module and the electrical port is turned on to electrically connect the electrical port to the target laser driving module, thereby driving the optical signal transmitting module with the electrical signal received by the electrical port to convert the electrical signal into an optical signal.

[0215] In some implementations, the use time of each laser driver module can be predicted based on the data type information, historical transmission information volume, real-time information volume, and historical transmission duration of each electrical port, and the target second-type driver module corresponding to the electrical port can be controlled to be turned on during the use time. That is, during the use time, the electrical port can always use the corresponding target laser driver module without re-determining the target laser driver module.

[0216] Optionally, multiple model characteristic parameters are calculated according to the data type information, the real-time information volume, the historical transmission time point and the historical transmission duration, and a prediction equation is constructed according to the multiple model characteristic parameters, and then the prediction equation is used to predict the use time of the laser driving module. For specific methods, refer to the content in step S130.

[0218] In some embodiments, after step S230, in the signal transceiver unit, when one electrical port is controlled to be switched to be electrically connected to the laser driving module first, it is determined that another electrical port needs to send an electrical signal obtained by converting the optical signal into an electrical signal by the optical signal receiving module.

[0219] Optionally, when another electrical port also needs to drive the optical signal transmitting module to convert the electrical signal into an optical signal through the electrical signal received by the electrical port, and the weight corresponding to the other electrical port is greater than the weight corresponding to the current electrical port, it is determined that an electrical port needs to continue to be electrically connected to the corresponding target laser driving module, and the driving demand of the current electrical port is added to the second demand queue list, and then the laser driving module electrically connected to the electrical port with a smaller weight than the current electrical port or the idle laser driving module is searched once every period of time according to the second connection relationship information and the laser driving module usage status information. When the search is successful, the currently found laser driving module is used as the target laser driving module corresponding to the current electrical port, and the driving demand of the current electrical port is deleted from the second demand queue list, otherwise the search continues.

[0220] In some embodiments, when the optoelectronic transceiver device further includes a third type driving module, a fourth type driving module, an encoding module, and a decoding module, after step S120, step S100 further includes steps S140 to S150.

[0221] Step S140: Determine the target encoding module corresponding to the electrical port.

[0222] In some implementations, a target coding mode of the electrical port is determined, and then a target coding module corresponding to the electrical port is determined according to the target coding mode.

[0223] In some embodiments, determining a target encoding method of an electrical port includes: obtaining first correspondence information between data type information and a preset encoding method, determining the target encoding method of the electrical port based on the data type information corresponding to the electrical port and the first correspondence information, and then determining a target encoding module corresponding to the electrical port based on the target encoding method.

[0224] Optionally, one type of data type information corresponds to a preset encoding method.

The calculation amount of the complex coding method is larger than that of the simple coding method, but error correction can be performed, which can improve the reliability of transmission.

[0226] Optionally, a corresponding preset encoding method is determined in advance according to the data type information, and first corresponding relationship information between the data type information and the preset encoding method is obtained. For example, the upload data type corresponds to a simple encoding method, and the download data type and the interactive data type both correspond to complex encoding methods. Exemplarily, the live broadcast data type corresponds to Manchester encoding, and the video data type corresponds to Turbo encoding.

[0227] In some implementations, one coding module corresponds to one coding mode, and the target coding module corresponding to the electrical port is determined according to the target coding mode and the coding mode corresponding to each coding module in the plurality of coding modules, wherein the target coding module is used to implement the target coding mode.

[0228] In some implementations, when an electrical port is connected to only one encoding module, the encoding mode corresponding to the encoding module is the target encoding mode of the electrical port, and the target encoding module corresponding to the electrical port is the encoding module connected to the electrical port.

Exemplarily, based on the correspondence of the live data type to Manchester encoding, it is determined that the live data type corresponds to Manchester decoding. Based on the correspondence of the video data type to Turbo encoding, it is determined that the video data type corresponds to Turbo decoding. In this way, the electrical signal can be correctly decoded.
