With development of optical communication technologies, an optical communication network is increasingly used in various network communication systems. When an optical communication network facility is faulty, for example, an optical fiber is broken or damaged, security, stability, and reliability of the network communication system are greatly affected. However, an environment in which the optical fiber is located is complex, for example, being underwater, buried underground, or in a building. When artificial vibration or natural vibration occurs near the optical fiber, the optical fiber is easily broken and damaged.

The optical-to-electrical conversion circuit 102 is configured to: receive an optical signal, transmit an optical signal, and convert an optical signal into an electrical signal. After processing the electrical signal to obtain service data, the electrical signal processing circuit 104 outputs the service data, via the electrical signal interface circuit 106, to an optical communication system to which the optical-electrical apparatus 100 belongs.
However, in a process in which the optical signal is propagated in an optical fiber, an environment in which the optical fiber is located may vibrate due to natural or human reasons, causing an exception in a communication network, for example, the optical fiber is damaged or broken. The reason for such vibration may be an earthquake in nature, other ground vibration, or may be a human factor, for example, construction beside an optical fiber line. This is not limited herein. Details are not described one by one. When such an exception occurs, the optical-electrical apparatus 100 cannot upload the environment condition information, in a timely and accurate manner, to the optical communication system to which the optical-electrical apparatus 100 belongs, and therefore cannot prevent or reduce damage to the optical fiber.

Optionally, the first parameter includes the optical polarization parameter. In a process of converting the optical signal into the electrical signal and obtaining the service data from the electrical signal, the optical-electrical apparatus originally needs to obtain the polarization parameter of the optical signal through parsing.

The report control circuit 510 is adapted to configure a report mode of the status information of the optical signal, which includes but is not limited to: for example, when the status information of the optical signal changes, the status detection circuit 500 actively reports the status information to a system. Alternatively, in some scenarios, a report function is disabled, to prevent data flooding and channel congestion caused by reporting. In addition, precise report control may be performed based on content of the status information of the optical signal. For example, a report frequency may be adjusted and controlled, for example, a report action is controlled based on a pre-forward error correction bit error rate, a post-forward error correction bit error rate, and/or optical power in the status information of the optical signal. The filter circuit 506 and the report control circuit 510 may help select target status information of the optical signal, and report the target status information in a proper report mode, thereby avoiding increasing processing load on the system.

Alternatively, the computer-readable program instructions may be loaded onto a computer, another programmable data processing apparatus, or another device, so that a series of operation steps are performed on the computer, the another programmable data processing apparatus, or the another device to produce a computer-implemented process. Therefore, the instructions executed on the computer, the another programmable data processing apparatus, or the another device implement functions/actions specified in one or more blocks in the flowcharts and/or the block diagrams.
The flowcharts and the block diagrams in the appended drawings illustrate system architectures, functions, and operations of possible implementations of apparatuses, systems, methods, and computer program products according to a plurality of embodiments of this application.

In some alternative implementations, the functions marked in the blocks may also occur in a sequence different from that marked in the accompanying drawings. For example, two consecutive blocks may actually be executed substantially in parallel, and sometimes may be executed in a reverse order, depending on a function involved.
It should also be noted that each block in the block diagrams and/or the flowcharts and a combination of blocks in the block diagrams and/or the flowcharts may be implemented by hardware (for example, a circuit, an ASIC, or an FPGA) that performs a corresponding function or action, or may be implemented by a combination of hardware and software, for example, firmware.
