For example, the multiplexer/demultiplexer 230 may be of the type 1 × 2, 1 × 4, 1 × 6, 1 × 8, 1 × 12, 1 × 16, 1 × 18, etc. Taking the multiplexer/demultiplexer 230 shown in fig. 2 as an example, the multiplexer/demultiplexer 230 is a 1 × 6 type, and has a first optical path 231, three second optical paths 232, and three third optical paths 233. Of course, in other embodiments, the number of the second light path 232 and the third light path 233 can be selected by one skilled in the art according to the requirement.
The 5G optical signal transmission apparatus 200 in the present application will be further described with the wavelength multiplexer/demultiplexer 230 being a 1 × 6 type.
It is contemplated that the monitoring management module 240 of the present application may need to monitor the optical paths of the first optical fiber 211 and the second optical fiber 212. Based on this, in an embodiment, the 5G optical signal transmission apparatus 200 further includes two first optical splitters 250, and the monitoring management module 240 includes a first detector 241 and a first signal processing circuit 242.

It is contemplated that the monitoring management module 240 of the present application may need to monitor the second optical path 232 of the wavelength multiplexer/demultiplexer 230. Based on this, in an embodiment, the 5G optical signal transmission apparatus 200 further includes three second optical splitters 260, and the monitoring management module 240 includes a second detector 243 and a second signal processing circuit 244. Since the number of the second optical paths 232 of the multiplexer/demultiplexer 230 is 3, the number of the second detectors 243 and the number of the second signal processing circuits 244 are 3, and the second detectors and the second signal processing circuits are respectively used for detecting optical signals in the corresponding optical paths.

It is considered that the monitoring management module 240 in the present application needs to monitor the third optical path 233 of the multiplexer/demultiplexer 230. Based on this, in an embodiment, the 5G optical signal transmission apparatus 200 further includes three third optical splitters 270, and the monitoring management module 240 includes a third detector 245 and a third signal processing circuit 246. Since the number of the third optical paths 233 of the multiplexer/demultiplexer 230 is 3, the number of the third detectors 245 and the third signal processing circuits 246 is 3, and the third detectors and the third signal processing circuits are respectively used for detecting optical signals in the corresponding optical paths.
Each third optical splitter 270 is disposed in each third optical path 233, and is configured to split the third optical path 233 into a third transmission path 2332 and a third detection path 2331, the third detector 245 and the third signal processing circuit 246 are located on the third detection path 2331, and the third transmission path 2332 serves as a receiving optical path, and sends the received optical signal to the wavelength multiplexer/demultiplexer 230 for multiplexing, so as to form a single-beam multi-wavelength optical signal.

Among them, the first signal processing circuit 242 may include a primary amplification circuit 2421, a secondary amplification circuit 2422, and a comparison circuit 2423. The first detector 241 is configured to detect characteristic parameters of the optical signal in the first detection path 2111, such as optical power, a center wavelength, and an analog signal of a clock signal, and send the characteristic parameters to the first-stage amplification circuit 242; the primary amplification circuit 2412 amplifies the voltage value in the analog signal, filters background noise and sends the filtered background noise to the secondary amplification circuit 2421; the secondary amplification circuit 2413 amplifies the power value of the analog signal to form a voltage waveform diagram and generates the voltage waveform diagram to the comparison circuit 2423; the comparator 2423 compares the voltage waveform pattern with a preset threshold. And outputting the signal when the signal is greater than the preset threshold value, and not outputting the signal when the signal is less than the preset threshold value, so that the process of converting the analog signal into the digital signal is realized, and the encoding process of the characteristic parameters of the optical signal is completed.
