Embodiment Construction
[0031] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present invention. Rather, they are merely examples of apparatuses and methods consistent with aspects of the invention as recited in the appended claims.
[0032] figure 2 It is a schematic diagram of an updating process of a real-time digital semaphore provided by an embodiment of the present invention. Because many real-time digital semaphores of optical modules do not occupy 1 byte, they usually occupy 2 bytes, that is, real-time digital semaphores are multi-byte semaphores, so each byte needs to be updated sequentially. When the optical modu...

The invention discloses a processing method and device and a reading method and device for monitoring parameters in an optical module and the optical module. Particularly, a data buffer region for storing monitoring parameters in the optical module is divided into at least three buffer regions, and the second buffer region is provided with a flag bit for indicating current state of the second buffer region. When the second buffer region is in data updating, a save flag bit of the second buffer region is first identifier information, it is indicated that inner data of the second buffer region is incomplete; when reading a command by a bus interface is about to occur, and data is returned from the third buffer region to a device that issues the bus interface to read the command; on the contrary, when the save flag bit of the second buffer region is second identifier information, it is indicated that the inner data of the second buffer region is complete, and data is returned from the second buffer region to the device that issues the bus interface to read the command. Therefore, the problem can be avoided that since reading of the bus interface conflicts with data updating, mistaken update data is read, a calibration curve is deviated and monitoring quantity precision is affected.
Description
technical field [0001] The invention relates to the technical field of optical communication, in particular to a processing method, a reading method, a device and an optical module for monitoring parameters in an optical module. Background technique [0002] Optical transceiver integrated module, referred to as optical module, is a standard module used in the field of optical communication. Due to the influence of external factors in the actual application process of the optical module, its function will be abnormal, resulting in errors in communication data. Therefore, as a network management unit in an optical fiber communication system, it is necessary to monitor the current operating status of the optical module in real time to ensure that the optical module can always transmit data under normal working conditions. [0003] In the current optical fiber communication system, the network management unit can monitor the monitoring parameters such as the temperature of the ...
