Existing communication devices begin to employ semi-active wavelength division multiplexing systems (Wavelength Division Multiplexing, WDM) to manage and control the transceiving processes of optical modules. The semi-active method comprises the steps of adding a monitoring interface and an active monitoring board card on a Distributed Unit (DU) side, and adding a small amount of maintenance functions; the active antenna unit (Active Antenna Unit, AAU) side is passive, only a passive multiplexer/demultiplexer is deployed; or the active side of the distributed unit is provided with active equipment, the local side equipment supports the monitoring and control of the far-end optical module, the active side of the antenna unit is passive, and only the passive multiplexer/demultiplexer is provided. Wavelength division multiplexing systems typically combine two or more optical carrier signals of different wavelengths at a transmitting end via a Multiplexer (also known as a Multiplexer) and couple the signals to the same optical fiber of an optical line for transmission, and at a receiving end separate the optical carriers of different wavelengths via a Demultiplexer (also known as a Demultiplexer or a de-Multiplexer) and then further process the separated signals by an optical receiver to recover the original signals. However, the existing semi-active wavelength division multiplexing system generally directly processes the transmitted and received optical carrier signals, and the processing process is slower, so that the transmission rate of the optical carrier signals is affected.
Therefore, the application provides a semi-active wavelength division multiplexing system, which screens received optical carrier signals through a data preprocessing module, distinguishes the optical carrier signals through a data control module, and stores the optical carrier signals through a data storage module respectively so as to be used later, thereby greatly improving the processing process of the optical carrier signals, improving the transmission rate of the optical carrier signals and being more suitable for the development direction of 4G/5G in the future.
The following describes an exemplary embodiment of a semi-active wavelength division multiplexing system provided in the present application with reference to the accompanying drawings.
Fig. 1 is a schematic structural diagram of a semi-active wavelength division multiplexing system according to an embodiment of the present application. Referring to fig. 1, illustratively, a semi-active wavelength division multiplexing system 100 includes a data preprocessing module 1, a data control module 2, and a data storage module 3; the data control module 2 is electrically connected with the data preprocessing module 1 and the data storage module 3 respectively.
The data preprocessing module 1 is configured to store and send the optical carrier signal to the data control module 2 when the received optical carrier signal meets a preset waveform condition.
A data control module 2 configured to transmit the optical carrier signals to the data storage module, respectively, when the optical carrier signals meet a buffer condition or a reservation condition; when the data request signal is received, the buffered data 3 is output.
A data storage module 3 configured to store the optical carrier signal conforming to the buffering condition as buffered data; and storing the optical carrier signals meeting the reservation condition as reserved data.
In this embodiment of the present application, the data preprocessing module 1 receives the optical carrier signal first, then determines whether the optical carrier signal meets a preset waveform condition, and stores and sends the optical carrier signal to the data control module 2 when the optical carrier signal meets the preset waveform condition. The data control module 2 is used for judging whether the optical carrier signal meets the reservation condition, when the optical carrier signal meets the reservation condition, the data storage module 3 is used for storing the optical carrier signal as reserved data, otherwise, the data storage module 3 is used for judging that the optical carrier signal meets the buffer condition, and the data storage module 3 is used for storing the optical carrier signal as buffer data so as to output the buffer data to other external terminal equipment, so that the received optical carrier signal is screened and distinguished, the processing process of the optical carrier signal is effectively improved, the transmission rate of the optical carrier signal is improved, and the method can be more suitable for the development direction of 4G/5G in the future.
As shown in fig. 1, the data preprocessing module 1 includes, illustratively, a manchester waveform unit 11 and a data filtering unit 12; the data filtering unit 12 is electrically connected to the manchester waveform unit 11 and the data control module 2, respectively.
The manchester waveform unit 11 is configured to convert the optical carrier signal into binary data when the received optical carrier signal complies with the manchester waveform rule.
The data filtering unit 12 is configured to store the valid frame header data and a predetermined number of byte data as one frame data after the valid frame header data when the binary data matches the valid frame header data.
In this embodiment of the present application, the received optical carrier signal is first detected by the manchester waveform unit 11, and when the received optical carrier signal meets the manchester encoding waveform rule, the optical carrier signal is converted into binary data, otherwise, the binary data is not processed. The binary data is then received by the data filtering unit 12 and stored in a first-in first-out queue (First Input First Output, FIFO). And then judging whether binary data stored in the first-in first-out queue accords with the head data of the effective frame, and storing the head data of the effective frame and the byte data of the preset number later into one frame of data in real time when the binary data accords with the head data of the effective frame. Otherwise, the processing is not performed. The preset number may include 64.
Among them, manchester encoding (Manchester Encoding), also called Phase Encoding (PE), is a synchronous clock encoding technique used by the physical layer to Encode the clock and data of a synchronous bit stream. The application of the method in the Ethernet medium system belongs to a self-synchronization method (the other is an external synchronization method) in two bit synchronization methods in data communication, namely, a receiver extracts a synchronization signal from the signal by utilizing special codes containing the synchronization signal to lock the clock pulse frequency of the receiver, thereby achieving the purpose of synchronization. Manchester encoding is commonly used for local area network transmissions. The Manchester code includes a clock and data in a data stream, and simultaneously transmits code information and clock synchronization signals to each other, each bit code has a jump, no direct current component exists, so that the Manchester code has self-synchronization capability and good anti-interference performance, but each code element is modulated into two levels, and the data transmission rate is only 1/2 of the modulation rate.
In addition, when invalid clutter is encountered in the receiving process of one frame of data, the stored data is deleted, and whether binary data stored in the first-in first-out queue accords with valid frame head data is judged again.

The data control unit 22 is configured to output the buffered data when receiving the data request signal.
In this embodiment of the present application, the data analysis unit 21 receives the optical carrier signals sent after the screening by the data preprocessing module 1, determines whether the optical carrier signals meet the buffering condition or the reservation condition, and sends the optical carrier signals respectively meeting the buffering condition and the reservation condition to the data storage module 3. The data request signal transmitted from the external device is received through the data control unit 22, and in the case where it is confirmed that there is buffered data, the buffered data is output.
Wherein, the reservation condition includes reservation activity (keep) frame data, keep-alive is a built-in component whose function is to cache inactive components. Since in general the components will default to destruction when they switch. If a certain component is required to be switched and then is not destroyed, the state before being saved can be realized by using a keep-alive.
Illustratively, as shown in fig. 1, the data storage module 3 includes a data caching unit 31 and a data retaining unit 32; the data buffer unit 31 and the data retention unit 32 are electrically connected to the data control module 2, respectively.

In the embodiment of the present application, the data buffer unit 31 receives the optical carrier signal meeting the buffer condition sent by the data control module 2, and stores the optical carrier signal as buffer data, so that the mobile external device requests to use the optical carrier signal. The reserved-conditional optical carrier signal transmitted from the data control module 2 is received by the data reservation unit 32 and stored as reserved data (i.e., keep alive on-line status signal). Meanwhile, when the optical carrier signal meeting the reservation condition is not received for more than the preset time, a disconnection signal is output, otherwise, the on-line state is kept.
