The target optical fiber is any one of at least one optical fiber connected with the integrated optical module.

Illustratively, the optical fiber to which the integrated optical module is connected includes: fiber a, fiber B, and fiber C. The target fiber may be fiber a. Alternatively, the target fiber may be fiber B. Still alternatively, the target fiber may be fiber C.

It should be noted that the target optical fiber may be an optical fiber used when the integrated optical module receives an optical signal. Alternatively, the target optical fiber may be an optical fiber used when the optical integrated module transmits an optical signal.

In one possible implementation, the target optical fiber is an optical fiber used by the integrated optical module to receive the optical signal. That is, the optical integrated module may receive the first sensing optical signal transmitted by the optical module at the other end of the target optical fiber through the target optical fiber.

Illustratively, an optical fiber a and an optical fiber B are connected between the optical module a and the optical module B. The optical fiber A is a target optical fiber of the optical module A, and the optical fiber B is a target optical fiber of the optical module B. The optical module a can receive the optical signal a (i.e. the first transmitted optical signal) from the optical module B through the optical fiber a, and the optical module B can receive the optical signal B (i.e. the first transmitted optical signal) from the optical module a through the optical fiber B.

In another possible implementation, the target optical fiber is an optical fiber used when the integrated optical module transmits an optical signal. That is, the target optical fiber may backscatter (or reflect) the optical signal when the target optical fiber is transmitting the optical signal.

It should be noted that the optical signal transmitted by the target optical fiber and the optical signal backscattered by the target optical fiber may be the same, or the optical signal transmitted by the target optical fiber and the optical signal backscattered by the target optical fiber may be different.

For example, the status information of the optical fiber may include: temperature of the optical fiber, length of the optical fiber. For another example, the status information of the optical fiber may include: the pressure of the fiber. For another example, the status information of the optical fiber may include: vibration of the optical fiber.

In this embodiment, the first preset corresponding relationship includes: a correspondence between a signal parameter of the first sensed light signal and the target state information.

In addition, the signal parameters are not limited in the embodiments of the present application. For example, the signal parameters may include: amplitude of the optical signal, wavelength of the optical signal, phase of the optical signal. As another example, the signal parameters may include: polarization of the optical signal, frequency shift of the optical signal.

In the following, with reference to a specific example, the determination of the target state information by the optical integration module according to the signal parameter of the first sensing optical signal and the first preset corresponding relationship is described.

Illustratively, the first preset correspondence includes: the correspondence between amplitude 7 (i.e. signal parameter) and pressure 18 (i.e. status information), the correspondence between frequency shift 11 and temperature 33, shock 21. If the signal parameters of the first sensing optical signal include: amplitude 7, frequency shift 11, the target state information includes: pressure 18, temperature 33, vibration 21.

And S303, the integrated optical module obtains a first communication optical signal according to the target state information and the second preset corresponding relation.

Wherein the second preset corresponding relationship comprises: a correspondence between the target state information and the signal parameter of the first communication optical signal.

Illustratively, the second preset corresponding relationship includes: the correspondence between pressure 18 and wavelength 25, and the correspondence between temperature 22 and power 31.

In one possible implementation manner, the optical integration module stores a plurality of preset communication optical signals. The optical integration module may determine the first communication optical signal from the plurality of preset communication optical signals according to the target state information and the second preset correspondence.

Illustratively, the plurality of preset communication optical signals stored by the optical transceiver module includes: optical signal a, optical signal B, and optical signal C. Wherein, the signal parameters of the optical signal A include: wavelength 13, power 25, signal parameters of optical signal B include: wavelength 11, power 19, signal parameters of optical signal C include: wavelength 11, power 32. If the second predetermined correspondence includes: the correspondence between the vibration 21 and the wavelength 11, the correspondence between the temperature 22 and the power 19, and the target state information includes: and vibrating 21 and temperature 22, the optical integration module determines that the optical signal B is a first communication optical signal.

In this embodiment, the first communication optical signal may carry service information.

It should be noted that, in the embodiment of the present application, service information is not limited. For example, the service information may be voice information. For another example, the service information may be character information. As another example, the service information may be video information.

In some embodiments, if the target optical fiber is an optical fiber used by the optical integrated module to transmit the optical signal, the optical integrated module may perform S304.

The technical scheme provided by the embodiment at least has the following beneficial effects: the integrated optical module can acquire a first sensing signal through the target optical fiber. Then, the optical integration module may determine the target state information according to the signal parameter of the first sensing optical signal and the first preset corresponding relationship. Wherein, the first preset corresponding relation comprises: and the corresponding relation between the signal parameter of the first sensing optical signal and the target state information, wherein the target state information is the state information of the target optical fiber. That is, the optical integrated module may determine the status information of the optical fiber according to the signal parameter of the sensing optical signal. Therefore, valuable reference can be provided for the maintenance management of the optical fiber, and the efficiency of the maintenance management of the optical fiber is improved. And the integrated optical module obtains a first communication optical signal according to the target state information and the second preset corresponding relation. Wherein the second preset corresponding relationship comprises: a correspondence between the target state information and the signal parameter of the first communication optical signal. Thereafter, the optical integrated module may transmit the first communication optical signal through the target optical fiber. That is, the optical integrated module may select a communication optical signal suitable for transmission in the optical fiber according to the state information of the optical fiber. Therefore, the distortion of the communication optical signal can be avoided, and the integrity of the service information carried by the communication optical signal is further ensured.

In other embodiments, if the target optical fiber is an optical fiber used by the optical integration module to receive the optical signal, after the optical integration module determines the target state information, the optical integration module may send a third communication optical signal carrying the target state information to the target optical module through the first optical fiber. The target optical module is an optical module at the other end of the target optical fiber, and the first optical fiber is an optical fiber used when the integrated optical module sends an optical signal to the target optical module. Then, the target optical module may acquire the target state information through the first optical fiber. Then, the target optical module may obtain the first communication optical signal according to the target status information (as the embodiment shown in S303 above).

It can be understood that the target optical module may not only determine the target status information according to the sensing optical signal scattered in the target optical fiber, but also obtain the target status information from the optical integrator module through the first optical fiber. Therefore, the method for the target optical module to acquire the target state information can be increased, the time for the target optical module to select the communication optical signal suitable for being transmitted in the target optical fiber is reduced, and the efficiency for the target optical module to transmit the communication optical signal through the target optical fiber is improved.

The integrated optical module may determine the target state information according to the first preset correspondence, and a difference between the phase of the first sensing optical signal and the phase of the second sensing optical signal.

As shown in fig. 4, before S302, S401 may be further included in the signal transmission method.

In this embodiment, S302 may include: S402-S403.

S402, the integrated optical module determines a target phase difference according to the phase of the first sensing optical signal and the phase of the second sensing optical signal.

Illustratively, if the phase of the first sensing optical signal is 12 and the phase of the second sensing optical signal is 15, the integrated optical module determines that the target phase difference is 3.

And S403, determining target state information by the integrated optical module according to the target phase difference and the first preset corresponding relation.

Illustratively, the first preset correspondence includes: the method comprises the steps of presetting a corresponding relation between a phase difference A and preset state information A, and presetting a corresponding relation between a phase difference B and preset state information B. Wherein, the preset phase difference a is 5, the preset phase difference B is 11, and the preset state information a includes: temperature 24, concentration 51, preset state information B includes: vibration 20, pressure 7. If the target phase difference is 5, the determining of the target state information by the optical integration module includes: temperature 24, concentration 51.

And the integrated optical module can determine the state of the target optical fiber according to the phase change, provide valuable reference for the maintenance and management of the optical fiber and improve the efficiency of the maintenance and management of the optical fiber.

In some embodiments, the optical integration module may multiplex the second sensing optical signal with the first communication optical signal to obtain a third target optical signal, where the third target optical signal includes: the second sensing optical signal is in communication with the first communication optical signal. The optical integrated module may then transmit a third target optical signal over the target optical fiber.

It should be noted that, for the description of the process of the optical integration module combining the second sensing optical signal and the first communication optical signal to obtain the third target optical signal, reference may be made to the description of using a wavelength division multiplexing technology to combine optical signals in the conventional technology, which is not described herein again.

And the difference between the wavelength of the communication optical signal and the wavelength of the sensing optical signal is greater than a preset wavelength difference threshold, and the difference between the power of the communication optical signal and the power of the sensing optical signal is greater than a preset power difference threshold, so that the interference between the communication optical signal and the sensing optical signal is reduced in the process of transmitting the communication optical signal and the sensing optical signal through the same optical fiber.

In one possible implementation manner, the optical integrated module may receive a first scattered target optical signal through a target optical fiber, where the first scattered target optical signal includes: the first sensing optical signal. Then, the optical integration module may demultiplex the first target optical signal to obtain a first sensing optical signal.

In some embodiments, the first target optical signal may further include: a second communication optical signal. The second communication optical signal carries second service information.

It should be noted that the first service information and the second service information may be the same. Alternatively, the first service information and the second service information may be different.

In a possible implementation manner, the optical integration module may determine whether the target state information satisfies a preset state condition according to a first light sensing signal in the scattered first target light signal. And if the integrated optical module determines that the target state information does not meet the preset state condition, the integrated optical module determines that the first service information is the second service information.

That is, by determining whether the target state information satisfies the preset state condition, it can be determined whether the service information carried by the communication optical signal transmitted in the target optical fiber is complete. And if the integrated optical module determines that the target state information does not meet the preset state information, determining that the service information carried by the communication optical signal transmitted in the target optical fiber is not complete. And the integrated optical module can send the service information again according to a proper communication optical signal, and the optical module at the other end of the target optical fiber can be ensured to receive complete service information.

In some embodiments, after the optical integration module determines the target state information, the optical integration module may determine the target receiving sensitivity according to the target state information and a fourth preset corresponding relationship. Wherein, the fourth preset corresponding relationship includes: and presetting a corresponding relation between the state information and the receiving sensitivity, wherein the target receiving sensitivity is the receiving sensitivity of the integrated optical module for receiving the optical signal through the target optical fiber.

Illustratively, the fourth preset correspondence includes: the corresponding relation between the preset state information A and the preset receiving sensitivity A and the corresponding relation between the preset state information B and the preset receiving sensitivity B. Wherein, the preset state information a includes: temperature 37, pressure 21, preset state information B includes: the concentration 11, the preset reception sensitivity a was 12.2, and the preset reception sensitivity B was 19.4. If the target state information includes: temperature 37, pressure 21, the optical integrated module determines the target receive sensitivity to be 12.2.

It can be understood that, through the state information of the optical fiber, the integrated optical module can modulate the receiving sensitivity of the optical signal, ensure that the integrated optical module can identify and receive the optical signal transmitted in the optical fiber, and avoid missing the optical signal with low power in the optical fiber.
