Embodiment 1
[0033] According to an embodiment of the present invention, a method for acquiring state information of an optical module is provided, figure 2 is a flow chart of a method for obtaining optical module state information according to an embodiment of the present invention, such as figure 2 As shown, the method of the embodiment of the present invention includes steps S102-S104:
[0034] Step S102: Acquiring a signal indicating the presence status of the optical module;
[0035] Optionally, the signal of the in-position state of the above-mentioned optical module can be stored in the local memory and the external memory. In an optional implementation of this embodiment, the signal of the in-position state of the optical module is stored in the external memory. The external memory in the logic device. In another optional embodiment, acquiring the signal indicating the on-position state of the optical module further includes acquiring a level signal locally stored in the logic ...
Embodiment 2
[0052] According to another aspect of the embodiments of the present invention, a device for acquiring state information of an optical module is also provided. Figure 5 is a structural block diagram of the acquisition of optical module state information according to an embodiment of the present invention, such as Figure 5 As shown, the device includes: a first acquisition module 40 ; a second acquisition module 42 coupled to the first acquisition module 40 .
[0053] The first acquiring module 40 is configured to acquire a signal indicating the in-position status of the above-mentioned optical module;
[0054] Optionally, the signal of the in-position state of the above-mentioned optical module can be stored in the local memory and the external memory. In an optional implementation of this embodiment, the signal of the in-position state of the optical module is stored in the external memory. The external memory Located in the logic device, the first acquisition module 40 ac...
Embodiment 3
[0071] Figure 8 It is a schematic diagram of the connection relationship between the optical module interrupt line and the logic device according to the embodiment of the present invention, as shown in Figure 8 As shown, this implementation provides a set of IIC interfaces for accessing the internal registers of the optical module. In terms of hardware connection, the connection of the interrupt signal line is discarded, and the in-position signal line is connected to the logic device in a high-level manner. In terms of logic device register settings, the interrupt register is discarded, and the in-position status register is used. Only focus on whether the optical module is in place, and do not pay attention to whether the optical module has an interrupt signal output. Based on the above circuit connection, the processor polls the status of the optical module at regular intervals, continues polling for the optical module that is not in position, and reads the internal exce...
