Detailed Description

In order to make the technical solutions better understood by those skilled in the art, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application.

In some of the flows described in the specification and claims of this application and in the above-described figures, a number of operations are included that occur in a particular order, but it should be clearly understood that these operations may be performed out of order or in parallel as they occur herein, the number of operations, e.g., 101, 102, etc., merely being used to distinguish between various operations, and the number itself does not represent any order of performance. Additionally, the flows may include more or fewer operations, and the operations may be performed sequentially or in parallel. It should be noted that, the descriptions of "first", "second", etc. in this document are used for distinguishing different messages, devices, modules, etc., and do not represent a sequential order, nor limit the types of "first" and "second" to be different.

The embodiment of the application is mainly applied to an optical fiber communication scene, and the errors such as phase and amplitude generated by transmission are pre-compensated, so that the signal forwarding is less affected, a CDR module is not required to be configured in the optical module, and the structural complexity of the optical module is reduced.

In the prior art, a switch can realize the forwarding of signals. The switch can establish communication connection with the optical module to realize corresponding switching function. For example, in a signal forwarding scenario, an exchange may directly perform electrical signal transmission with a first electronic device, and an optical module in communication connection with the exchange may directly perform optical signal transmission with a second electronic device, where the exchange may send an electrical signal to the optical module, and the optical module converts the electrical signal into an optical signal and sends the optical signal to the second electronic device; the optical module can receive an optical signal sent by the second electronic device, convert the optical signal into an electrical signal, and send the electrical signal to the switch, where the switch can send the electrical signal sent by the optical module to the first electronic device. However, in the process of forwarding the electrical signal, the transmission of the electrical signal is affected due to the influence of noise during the transmission. In order to prevent the electric signal from being affected by the transmission channel after being forwarded, a CDR chip is usually added to the optical module, a clock signal in the electric signal is separated through a CDR pair, and the obtained clock signal is used to perform phase compensation on the electric signal and solve the problems of amplitude attenuation and the like, so as to reduce the transmission error of the electric signal.

In order to solve the above technical problem, the inventor thinks whether pre-compensation can be performed on phase, amplitude and the like in the channel transmission process so as to solve the transmission error problem in the channel transmission. Accordingly, the inventors propose a technical solution of the present application.

In the embodiment of the application, the switch may detect the signal loss information of the transmission channel based on the optical module, and may measure the influence of the transmission channel on the transmission signal by detecting the signal loss information of the transmission channel, and may further cancel the influence of the transmission channel on the signal to be transmitted by optimizing the signal, and may further optimize the signal to be transmitted based on the signal loss information to obtain the first target signal, where the first target signal is an optimized signal and forwards the first target signal.

The embodiments of the present application will be described in detail below with reference to the accompanying drawings.

As shown in fig. 1, a flowchart of an embodiment of a signal processing method provided in the embodiment of the present application may include the following steps:

The signal processing method can be applied to an exchanger or a signal processing system, wherein the signal processing system can comprise the exchanger and an optical module which is in communication connection with the exchanger, and the exchanger and the optical module in the application can be combined to realize network equipment for transmitting photoelectric signals.

Wherein signal loss information of the transmission channel can be detected by the switch based on the optical module. The signal loss information of the transmission channel may also be detected by an electronic device independent of the transmission scenario, where the electronic device may refer to a computer or an intelligent control terminal that monitors and controls the switch, and after the signal loss information of the transmission channel is detected, the signal loss information may also be sent to the switch. The switch may receive signal loss information transmitted by the electronic device.

Optionally, the switch detects the signal loss information of the transmission channel based on the optical module, and the signal loss information may be obtained by performing channel performance detection on the transmission channel between the optical module and the switch.

When the switch transmits the electrical signal to the first electronic device, noise may also be affected in a communication path of the electrical signal, and therefore, the transmission channel may further include a communication channel between the first electronic device and the switch. That is, the transmission channel may include a transmission channel of a communication circuit between the switch and the optical module, a fiber channel between the optical module and the second electronic device, and/or a communication channel between the switch and the first electronic device.

The switch optimizes the received electric signal based on the signal loss information, which means that the received electric signal is compensated for transmission on the basis of the signal loss information to offset the signal loss in the channel transmission process and reduce the transmission error generated by the channel transmission.

Optionally, the signal obtained by receiving may include an electrical signal received from the first electronic device, and may also include an electrical signal received from the optical module.

The first target signal may be obtained by performing optimization processing on the received electric signal through the signal loss information, and specifically may refer to performing phase compensation and/or amplitude adjustment on a signal to be transmitted through the signal loss information to counteract an influence of a transmission channel on the signal to be transmitted, so that a transmission error of the electric signal is reduced.
