[0040] In embodiments of the present invention, the term "and / or" describes the association relationship between associated objects, indicating that three possible relationships exist. For example, "A and / or B" can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone. The character " / " generally indicates that the associated objects are in an "or" relationship.

[0041] In the embodiments of the present application, the term "plurality" refers to two or more than two, and other quantifiers are similar.

[0042] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0043] See also Figure 1 , Figure 1 Schematic diagram of a signal detection system according to an embodiment of the present invention, the system may include: an optical splitter 101, a photoelectric detection module 102 and an optical module 103; wherein,

[0044] The optical splitter 101 has N channels, which is used to split the received signal, generate N channels of uplink optical signals, and send the uplink optical signals to the photoelectric detection module;

[0045] The optical module 103 is used to send a downlink optical signal to the photoelectric detection module 102;

[0046] The photoelectric detection module 102 is arranged in the uplink optical path and / or downlink optical path of M channels among the N channels, and is used to demodulate low-speed management information from the received uplink optical signal and / or downlink optical signal; wherein M and N are both integers greater than 0, and M≤N; the uplink optical signal and the downlink optical signal include low-speed management information.

[0047] In the embodiment of the present invention, the photoelectric detection module may be arranged in the uplink optical path, may be arranged in the downlink optical path, or may be arranged in both the uplink and downlink optical paths.

[0048] In a specific application, for a target channel among M channels, if a photoelectric detection module is provided on the uplink optical path of the target channel, in the uplink direction, the photoelectric detection module is used to demodulate the low-speed management information from the uplink optical signal corresponding to the target channel. If a photoelectric detection module is provided on the downlink optical path of the target channel, in the downlink direction, the photoelectric detection module is used to demodulate the low-speed management information from the downlink optical signal received by the optical module corresponding to the target channel. The target channel refers to any channel among the M channels.

[0049] Specifically, the photoelectric detection module is used to extract the low-frequency signal from the received signal to obtain the low-speed management information. During demodulation of the low-speed management information, the photoelectric detection module can, for example, perform photoelectric detection on the received signal to demodulate the electrical signal. The low-speed management information is then obtained through low-pass filtering. Furthermore, the photoelectric detection module can also perform operations such as shaping and discrimination on the low-speed management signal, depending on actual needs.

[0050] See also Figure 2 , Figure 2 : is a schematic diagram of a signal detection system according to an embodiment of the present invention. The system may include: an AAU (Active Antenna Unit) branch side 21 and a DU (Distributed Unit) branch side 22. The AAU branch side may include an optical module, an optical combiner, etc.; the DU branch side may include an optical splitter, a photoelectric detection module, an optical module, etc. In the embodiment of the present invention, according to the configuration of the photoelectric detection module, it can be divided into bidirectional detection, single uplink detection (AAU to DU), and single downlink detection (DU to AAU), as shown in FIG. Figure 3(a) to Figure 3(c) In Figure 3(a), the photoelectric detection module is set in the uplink and downlink optical paths; in Figure 3(b), the photoelectric detection module is set in the uplink optical path; in Figure 3(c), the photoelectric detection module is set in the downlink optical path.

[0051] On the AAU side, Figure 4 As shown, the low-speed management information is modulated onto the main service optical signal through the optical module using the modulation technology. Figure 5The spectrum distribution of the service signal and the low-speed management information optical signal is shown. The management information is mainly distributed around frequency k, and the service signal is mainly distributed around frequency f. In the uplink direction, the modulated optical signal is decomposed to the DU branch side through the optical combiner on the AAU branch side 21, the line-side optical fiber, and the optical splitter on the DU branch side 22. On the DU branch side, optical signals from channel 1 to channel N are obtained by splitting the light through the optical splitter. If a photoelectric detection module is provided in the uplink direction, the photoelectric detection module demodulates the signal received from the optical splitter to obtain the low-speed management information therein. In the downlink direction, the photoelectric detection module receives the optical signal sent by the corresponding photoelectric module on the DU branch side, demodulates it, and obtains the low-speed management information therein.

[0052] As can be seen from the above description, in this embodiment of the present invention, a photodetector is used to receive and demodulate the top modulation information of the local branch. This solution reuses existing MCU (Microcontroller Unit) chips, has a simple algorithm, and has a low technical threshold. Furthermore, the system can detect only the uplink top modulation signal or the downlink top modulation signal, providing flexible system design and reducing the number of photodetectors required by half. Furthermore, this solution can detect branch faults and easily increase the transmission rate.

[0054] Step 601: In the uplink direction, receive the uplink optical signal of the optical splitter, and demodulate the low-speed management information from the uplink optical signal, wherein the uplink optical signal includes the low-speed management information; and / or, in the downlink direction, receive the downlink optical signal sent by the optical module, and demodulate the low-speed management information from the downlink optical signal, wherein the downlink optical signal includes the low-speed management information.

[0055] Specifically, in this step, the photoelectric detection module extracts a low-frequency signal from the uplink optical signal to obtain the low-speed management information; and extracts a low-frequency signal from the downlink optical signal to obtain the low-speed management information.

[0056] During demodulation of the low-speed management information, the photoelectric detection module can, for example, perform photoelectric detection on the received signal to demodulate the electrical signal. The low-speed management information is then obtained through low-pass filtering. Furthermore, the photoelectric detection module can perform other operations, such as shaping and discrimination, on the low-speed management signal, as needed.

[0057] In the embodiment of the present invention, the photoelectric detection module is used to detect the uplink optical signal or the downlink optical signal, thereby completing the detection of the low-speed management information without using a dedicated chip. Therefore, the solution of the embodiment of the present invention can reduce the complexity of the low-speed management information detection.
