[0148] In the case where the computing device sends electrical signals such as data and / or control instructions to the network device, that is, the computing device as a sending end. The first connector 1011-1 can integrate at least one communication component to send at least one sending electrical signal into a first electrical signal of one way, and output the first electrical signal to the first signal converter.

[0149] In the case that the computing device receives the electrical signal such as data and / or control instruction sent by the network device, that is, the computing device as the receiving end. The first connector 1011-1 can receive the second electrical signal sent by the first signal converter, and decompose the second electrical signal into at least one second interface corresponding to at least one receiving electrical signal, and send the at least one receiving electrical signal to the corresponding communication component of the computing device through the at least one second interface.

[0155] Secondly, the use of the first management module 1012 will be described in detail.

[0156] The first management module 1012 can be used to control the optoelectronic conversion process of the first optoelectronic conversion module 1011 according to the first working state of the first optoelectronic conversion module 1011.

[0157] Optionally, the first management module can also be referred to as a "system control and management module", the first management module 1012 can further include a first detector 1012-1 and a first processor 1012-2. The first management module 1012 can detect the first working state of the first photoelectric conversion module 1011 through the first detector 1012-1, and send the first working state to the first processor 1012-2; the first management module 1012 can also control the photoelectric conversion process of the first photoelectric conversion module 1011 according to the first working state through the first processor 1012-2.

[0158] Next, the use of the first detector 1012-1 is described in detail.

[0159] The first detector 1012-1 can be used to detect the first working state of the first photoelectric conversion module 1011 and send the first working state to the first processor 1012-2.

[0160] The first working state can be a normal state or an abnormal state.

[0161] The first detector 1012-1 can be a sensor for signal detection, and the first detector 1012-1 can be connected to the first connector 1011-1 and the first signal converter 1011-2 in the first photoelectric conversion module 1011 respectively.

[0162] The first detector can be used to detect the working state of the first connector 1011-1 and the working state of the first signal converter 1011-2, and determine the first working state according to the working state of the first connector 1011-1 and the working state of the first signal converter 1011-2. It can be understood that in the case that the working state of the first connector 1011-1 and the working state of the first signal converter 1011-2 are both normal states, the first working state is a normal state; in the case that the working state of the first connector 1011-1 and / or the working state of the first signal converter 1011-2 is an abnormal state, the first working state is an abnormal state.

[0163] The first detector 1012-1 can be used to detect the connection state and signal transmission information of the first interface and the connection state and signal transmission information of each second interface in the first connector 1011-1 in real time, and send the connection state and signal transmission information of the first interface and the connection state and signal transmission information of each second interface to the first processor in real time.

[0164] The connection state can include a normal connection state or an abnormal connection state.

[0165] The signal transmission information can be used to indicate whether there is signal transmission at the interface, and in the case of signal transmission, the signal transmission information can include the communication protocol and data specification of the signal, the bandwidth resource occupied by the signal, and the transmission result of the signal, which can be transmission success or transmission failure.

[0166] It can be understood that the working state of the first connector 1011-1 is an abnormal state in any of the following cases: the connection state is an abnormal connection state; the transmission result is transmission failure; the communication protocol of the signal does not conform to the standard communication protocol; and the data specification of the signal does not conform to the standard data specification.

[0168] The photoelectric conversion result can be conversion success or conversion failure.

[0169] The path information can be used to split the second electrical signal into at least one received electrical signal. Alternatively, the path information can be used to indicate the identity of the at least one second interface.

[0170] Next, the use of the first processor 1012-2 will be described in detail.

[0171] The first processor 1012-2 can be used to control the photoelectric conversion process of the first photoelectric conversion module 1011 according to the first working state. It can be understood that in the case where the first working state is a normal state, the first processor 1012-2 can start the first photoelectric conversion module 1011 to normally perform photoelectric conversion processing; in the case where the first working state is an abnormal state, the first processor 1012-2 can stop (or cut off) the photoelectric conversion processing process of the first photoelectric conversion module 1011 to ensure the safety of the first photoelectric conversion module.

[0172] The first processor can compare the communication protocol of the signal of each interface (the first interface or the second interface) with the standard communication protocol corresponding to each interface, and compare the data specification of the signal of each interface with the standard data specification corresponding to each interface, to determine whether the signal is a correct signal, avoid the occurrence of signal transmission errors, and ensure the accuracy of signal transmission.

[0173] In the case of photoelectric conversion failure, the signal cannot be transmitted correctly. In this case, the first processor can send an alarm prompt to the signal sending end (for example, a computing device or a network device) so that the signal sending end can re-execute the signal transmission process of data or control instructions based on the alarm prompt to ensure the stability of signal transmission.

[0174] The first processor can also control the first connector 1011-1 to split the second electrical signal into at least one received electrical signal corresponding to the at least one second interface according to the path information in the photoelectric conversion information of the first signal converter 1011-2, so that the first connector 1011-1 can route the at least one received electrical signal to the corresponding communication component in the computing device through the corresponding second interface, which is conducive to accurate splitting and routing of signals.

[0175] In some embodiments, the first processor can detect the transmission state of the optical signal of the first optical cable through the first detector; in the case of an abnormal state, switch the second optical cable for optical signal transmission to ensure the stability of signal transmission between the computing device and the network device, so that the service processing process based on the computing device and the network device can be stably and continuously run.

[0176] The first management module can monitor and manage the signal transmission process of the first photoelectric conversion module, so as to discover and handle various signal transmission problems that may exist in the photoelectric conversion process of the first photoelectric conversion module in time, ensure the stability and efficiency of the liquid cooling system under various operating conditions, reduce signal transmission interruption and other problems caused by signal transmission failure, and facilitate to ensure the stability and signal transmission efficiency of the first photoelectric conversion module in the signal transmission process.

[0178] The first optical cable 102 and the second optical cable 104 can be a channel for optical signal transmission, which can be composed of high-quality optical fibers.

[0179] It can be understood that in the liquid cooling system, the second optical cable 104 can be used as a backup optical cable for the first optical cable 102, so as to ensure stable signal transmission of the liquid cooling system in the case of failure of the first optical cable 102, avoid business interruption due to signal interruption, and facilitate to improve the fault tolerance and reliability of signal transmission of the liquid cooling system.

[0180] The physical cable can be used for electrical signal transmission, and in some environments (for example, a high-density device environment), the physical cable can generate electromagnetic interference or induction effect during electrical signal transmission. The liquid cooling system can convert the electrical signal transmission process into an optical signal transmission process through the first optoelectronic conversion module, so that the liquid cooling system can replace the physical cable with an optical cable during signal transmission. By canceling the physical cable, these electromagnetic interference problems can be eliminated, which helps to reduce the device failure rate during signal transmission and ensures the stability and security of signal transmission.

[0181] In some industrial control computer application scenarios, there can be a need for signal transmission processes to resist strong electromagnetic interference. In one example, the liquid cooling system (or signal transmission module) provided by the embodiments of the present application can be used as an additional device to be coupled with the industrial control computer to realize the signal transmission process of the industrial control computer through the liquid cooling system, thereby canceling the original physical cable used for signal transmission in the industrial control computer, which helps to eliminate electromagnetic interference and other problems caused by the physical cable, and ensures the stability and security of the industrial control computer signal transmission.
