For example: fig. 1b is a second schematic diagram of an optical signal processing system according to an exemplary embodiment of the disclosure, as shown in fig. 1b, in the optical processing system 200, the first optical processing device 103 includes a first optical processing module 1011 and a second optical processing module 1012, the second optical processing device 104 includes a third optical processing module 1013 and a fourth optical processing module 1014, and the third optical processing device 105 includes a fifth optical processing module 1015 and a sixth optical processing module 1016. The first optical processing module 1011 of the first optical processing apparatus 103 and the third optical processing module 1013 of the second optical processing apparatus 104 may be a first set of optical transmission modules, the second optical processing module 1012 of the first optical processing apparatus 103 and the fourth optical processing module 1014 of the second optical processing apparatus 104 may be a second set of optical transmission modules, the third optical processing module 1013 of the second optical processing apparatus 104 and the fifth optical processing module 1015 of the third optical processing apparatus 105 may be a third set of optical transmission modules, and the fourth optical processing module 1014 of the second optical processing apparatus 104 and the sixth optical processing module 1016 of the third optical processing apparatus 105 may be a fourth set of optical transmission modules. There may be multiple ports for an optical transport carrier, for example: the first optical transmission carrier 1021 includes: a port corresponding to the first optical processing module 1011 and a port corresponding to the second optical processing module 1013; third optical transport carrier 1023 includes: a port corresponding to the third optical processing module 1013, and a port corresponding to the sixth optical processing module 1016.

In one possible embodiment, the optical processing module can transmit an optical signal and can also receive an optical signal. For example: the first optical processing module 1011 can send the first optical signal to the third optical processing module 1013 through the first optical transmission carrier 1021, the second optical processing module 1012 can send the second optical signal to the fourth optical processing module 1014 through the second optical transmission carrier 1022, the first optical processing module 1011 can receive the third optical signal sent by the third optical processing module 1012 through the first optical transmission carrier 1021, and the second optical processing module 1012 can receive the fourth optical signal sent by the fourth optical processing module 1014 through the second optical transmission carrier 1022. The first optical signal and the fourth optical signal may have the same wavelength, the first optical signal may have a different wavelength from the second optical signal, and the second optical signal may have the same wavelength as the third optical signal. The third optical processing module 1013 may send the fifth optical signal to the fifth optical processing module 1013 through the third optical transport carrier 1023, the fourth optical processing module 1014 may send the sixth optical signal to the sixth optical processing module 1016 through the fourth optical transport carrier 1024, the third optical processing module 1013 may receive the seventh optical signal sent by the fifth optical processing module 1015 through the third optical transport carrier 1023, and the fourth optical processing module 1014 may receive the eighth optical signal sent by the sixth optical processing module 1016 through the fourth optical transport carrier 1024. The wavelength of the fifth optical signal may be the same as the wavelength of the eighth optical signal, the wavelength of the fifth optical signal may be different from the wavelength of the sixth optical signal, and the wavelength of the sixth optical signal may be the same as the wavelength of the seventh optical signal.

In the embodiment of the present disclosure, the optical processing module may be understood as a module for receiving an optical signal, such as an optical fiber repeater (also referred to as a base station or a station), an optical signal generator, a laser transmitter (also referred to as a laser), and a laser receiver (also referred to as an optical receiver). The optical signal sent by the optical processing module may be an optical signal generated by the optical processing module itself, or may also be an optical signal of a device such as another laser device that is forwarded, and the optical signal received by the optical processing module may be utilized by the optical processing module itself (e.g., the optical signal is analyzed to determine corresponding information), or may be forwarded to a device such as another laser device after being subjected to related processing (e.g., filtering processing). The optical transmission carrier is understood to be a carrier for transmitting optical signals, and optical fibers, air, transparent liquid and the like can be used as the optical transmission carrier. The optical transmission module has a plurality of ports facing different directions, such as: an input port for receiving an optical signal, an output port for transmitting an optical signal, a control port for adjusting transmission power (which may also be referred to as optical signal power) or transmission direction of an optical signal, and the like. In a possible embodiment, one port of the optical transmission module can be used as an input port of an optical signal, and the like.

In the embodiment of the present disclosure, the plurality of optical processing modules corresponding to the plurality of ports of the same optical transmission carrier may be referred to as a group of optical processing modules. For example: the optical transmission carrier has 2 ports, which are respectively connected with the first optical processing module and the second optical processing module, so that the first optical processing module and the second optical processing module can be the same optical processing module. The optical signal processing system can input the optical signal generated by the first optical processing module into the optical transmission carrier through the first port of the optical transmission carrier, and the optical signal can be input into the second optical processing module through the second port of the optical transmission carrier through the transmission of the optical transmission carrier.

Optical signals (also referred to as light waves) are understood to mean light or optical light or the like used for the transmission of information, different optical signals having different wavelengths. For example: the wavelength range of visible light is 380-780 nanometers (nm), and the wavelength range of ultraviolet light is 20-380 nm. In some embodiments, the optical signal may be divided into different bands according to the wavelength of the optical signal, each band may be used as a separate channel to transmit one or more optical signals with predetermined wavelengths, and the like. For example: the wavelength range of the Long (Long, L) band is 1565-. When Optical signals of different wave bands are adopted for transmission, the corresponding loss power consumption is different, the power loss corresponding to the S wave band is higher, and the Optical signals of the S wave band can be used for signal transmission under a short-distance scene, such as a Passive Optical Network (PON) system. The power loss corresponding to the C wave band is low, the long-distance optical fiber has great advantages in a long-distance transmission system, and can be used for signal transmission in the scenes of long-distance, ultra-long-distance and submarine optical transmission systems. The power loss corresponding to the L wave band is low, and the method can be used for signal transmission in the scenes of long-distance, ultra-long distance, submarine optical transmission systems and the like.

In the embodiment of the present disclosure, in the process of transmitting the optical signal in the optical transmission carrier, the optical signal has characteristics such as a signal wavelength, a signal number, a transmission direction, a transmission power, a transmission rate, a transmission loss, and the like, and a transmission mode (also referred to as a transmission policy) of the optical signal may be set according to one or more characteristics. In a possible embodiment, for optical signals of different wavelengths, transmission may be performed on the optical transmission carrier according to different transmission directions. For example: the transmission direction of the first optical signal in the optical transmission carrier may be from left to right, the transmission direction of the second optical signal in the optical transmission carrier may be from right to left, the transmission direction of the third optical signal in the optical transmission carrier may be from top to bottom, and the transmission direction of the fourth optical signal in the optical transmission carrier may be from bottom to top, etc.

In the embodiment of the present disclosure, after a plurality of optical signals are input from a plurality of ports facing different directions of an optical transmission carrier through a plurality of sets of optical processing modules, the optical transmission carrier may transmit the plurality of optical signals according to different transmission directions. Because the transmission directions of the optical signals are different, the optical transmission paths of the optical signals in the optical transmission carrier cannot be completely overlapped, namely can be completely not overlapped or partially overlapped, so that the transmission power of superposition of a plurality of optical signals can be reduced. In one possible embodiment, the transmission direction of the optical signal in the optical transmission carrier may be determined according to the port receiving the optical signal, for example: the optical transport carrier includes 2 ports, the first optical signal is input from the first port to the optical transport carrier, and then the transmission direction of the first optical signal may be a direction from the first port to the second port; the second optical signal is input to the optical transmission carrier from the second port, and the transmission direction of the second optical signal may be a direction from the second port to the first port. The transmission direction of the optical signal in the optical transmission carrier may also be determined according to the incident angle when being input to the optical transmission carrier, for example: the incident angle of the first optical signal input to the optical transmission carrier is 30 degrees, and then the transmission direction of the first optical signal may be 30 degrees; the incident angle of the second optical signal input to the optical transmission carrier is 60 degrees, then the transmission direction of the second optical signal may be 60 degrees, etc.

In a possible embodiment, taking 2 optical processing modules as a group, 2 optical transmission carriers, each optical transmission carrier including 2 ports, and a plurality of optical signals including an optical signal in a C-band and an optical signal in an L-band as an example, an optical signal in the C-band generated by a first optical processing module may be input into the first optical transmission carrier through a first port of the first optical transmission carrier, and then input into a second optical processing module through a second port of the first optical transmission carrier; the optical signal of the L waveband generated by the first optical processing module can be input into the second optical transmission carrier through the first port of the second optical transmission carrier and then input into the second optical processing module through the second port of the second optical transmission carrier; the optical signal of the C wave band generated by the second optical processing module can be input into the second optical transmission carrier through the second port of the second optical transmission carrier and then input into the first optical processing module through the first port of the second optical transmission carrier; the optical signal of the L-band generated by the second optical processing module can be input into the first optical transmission carrier through the second port of the first optical transmission carrier, and then input into the first optical processing module through the first port of the first optical transmission carrier.

In the embodiment of the present disclosure, by setting a plurality of groups of optical processing modules, each group of optical processing module includes: the optical processing module is configured to receive and transmit optical signals, and the optical transmission carriers are provided with a plurality of ports with different directions, each port corresponds to a different optical processing module in each group of optical processing modules, and then the optical transmission carriers can be used for transmitting the received optical signals to the corresponding optical processing modules according to different transmission directions under the condition that the optical signals are received from the ports. Compared with the method for transmitting the plurality of optical signals in the same transmission direction, the method for transmitting the plurality of optical signals in the transmission process of the plurality of optical signals can reduce the size of the transmission power superposed after the plurality of optical signals are superposed by setting different transmission directions of the plurality of optical signals for transmission.

Fig. 2 is a schematic structural diagram of a port according to an exemplary embodiment of the present disclosure, and in conjunction with fig. 1 and 2, a plurality of the ports with different orientations include:

a first port 201 and a second port 202, the first port 201 being parallel to and opposite to the second port 202;

when the optical processing module corresponding to the first port 201 inputs a first optical signal to the optical transport carrier 102 through the first port 201, and the optical processing module corresponding to the second port 202 inputs a second optical signal to the optical transport carrier 102 through the second port 202, an optical transmission path of the first optical signal in the optical transport carrier 102 and an optical transmission path of the second optical signal in the optical transport carrier 102 do not overlap at least partially.

In an embodiment of the present disclosure, the plurality of ports facing different directions may include at least: the first port and the second port are opposite in parallel, and the two ports can be on the same horizontal line or different horizontal lines. For example: the optical transmission path of the first optical signal is from the first port 201 to the port 204, and the optical transmission path of the second optical signal is from the second port 202 to the port 203, so that the optical transmission path of the first optical signal and the optical transmission path of the second optical signal only partially overlap. In a possible embodiment, the optical transmission carrier may be an optical fiber, the optical transmission module may be a base station, and the first port and the second port are two ends of the optical fiber respectively. The optical signal processing system can input a first optical signal generated by a first base station to an optical transmission carrier through a first port so as to transmit the first optical signal to a second base station; the second optical signal generated by the second base station may also be input to the optical transport carrier through the second port, and thus may be transmitted to the first base station, and so on. The transmission direction of the first optical signal may be a first port to second port direction, and the transmission direction of the second optical signal may be a second port to first port direction, that is, the transmission direction of the first optical signal is different from the transmission direction of the second optical signal.

In the embodiment of the disclosure, since the transmission direction of the first optical signal is different from the transmission direction of the second optical signal, the optical transmission path of the first optical signal in the optical transmission carrier is at least partially not overlapped with the optical transmission path of the second optical signal in the optical transmission carrier. The optical transmission path may be understood as an area or a position where an optical signal is transmitted in an optical transmission carrier, and the optical transmission path may be determined according to one or more factors, such as a transmission direction of the optical signal, a position of an input port, and a transmission rate of the optical signal, for example: optical signals with different wavelengths are input to the optical transmission carrier through the same port and the same transmission direction, so that the optical transmission paths of the optical signals with different wavelengths can be determined to be the same.

In a possible embodiment, the transmission power superimposed after superposition of the plurality of optical signals in the optical transmission carrier may be understood as the transmission power superimposed after superposition of the optical transmission paths. For example: the transmission power of the first optical signal is 200 milliwatts (mW), the transmission power of the second optical signal is 200 milliwatts, the current transmission power of the optical signal in the optical transmission carrier is 200 milliwatts if the optical transmission paths of the first optical signal and the second optical signal in the optical transmission carrier are not overlapped (i.e., it can be understood that the first optical signal or the second optical signal in a part of the optical transmission carrier is transmitted separately), and the current transmission power of the optical signal in the optical transmission carrier is 400 milliwatts if the optical transmission paths of the first optical signal and the second optical signal in the optical transmission carrier are overlapped. The larger the transmission power of the optical signal is, the larger the degree of Raman Scattering (SERS) generated by the optical signal is, that is, the transmission power of the optical signal is positively correlated with the degree of Raman Scattering. Raman scattering (also referred to as raman effect) is understood to mean that when an optical signal of a certain frequency is irradiated onto the surface of an optical transmission carrier, energy transfer occurs between molecules in a substance of the optical transmission carrier and photons of the optical signal, light of different frequencies and the like are scattered, and the transmission power of the optical signal is reduced, which results in reduction of the transmission distance of the optical signal and information carried by the optical signal.

In the embodiment of the disclosure, a first optical signal is input to an optical transmission carrier through a first port, a second optical signal is input to the optical transmission carrier through a second port, and then the first optical signal and the second optical signal are transmitted according to different transmission directions, so that an optical transmission path of the first optical signal in the optical transmission carrier and an optical transmission path of the second optical signal in the optical transmission carrier are at least partially misaligned, and further, transmission power of a plurality of optical signals overlapped can be used for suppressing raman scattering and reducing transmission loss of the optical signals.

Fig. 3 is a schematic diagram illustrating a transmission direction according to an exemplary embodiment of the disclosure, and in conjunction with fig. 1 and 3, the first optical signal 301 and the second optical signal 302 are input into the optical transmission carrier 102 in parallel, and a transmission direction of the first optical signal 301 in the optical transmission carrier 102 is opposite to a transmission direction of the second optical signal 302 in the optical transmission carrier.

In the embodiment of the disclosure, the first optical signal and the second optical signal are both input into the optical transmission carrier in parallel, and the transmission direction of the first optical signal in the optical transmission carrier may be opposite to the transmission direction of the second optical signal in the optical transmission carrier. For example: in the optical transmission carrier, the transmission direction of the first optical signal is horizontal to the right, the transmission direction of the first optical signal is horizontal to the left, and the like; or the transmission direction of the first optical signal is vertical upward, the transmission direction of the first optical signal is vertical downward, and the like.

In the embodiment of the disclosure, the first optical signal and the second optical signal are both input into the optical transmission carrier in parallel, and the transmission direction of the first optical signal in the optical transmission carrier and the transmission direction of the second optical signal in the optical transmission carrier can be opposite, so that the first optical signal and the second optical signal between the plurality of optical processing modules can be rapidly transmitted in the optical transmission carrier, and the optical transmission paths of the optical signals and the like are reduced.
