It is limited.On the contrary, these embodiments are provided to facilitate a more thoroughly understanding of the present invention, and can be by the scope of the present disclosure
It is fully disclosed to those skilled in the art.
Embodiment one
In order to solve the problems in the existing technology, the embodiment of the present invention provides a kind of communication failure investigation method, such as
Shown in Fig. 1, comprising the following steps:
S101, proximal device send malfunction elimination request sequence to remote equipment, and malfunction elimination request sequence is according to pre-
If the presence or absence of rule generation light sequence.
Proximal device can be with to the method that remote equipment sends malfunction elimination request sequence are as follows: the controller of proximal device is pressed
Preset rules are that the transmission enable end (TX_Disable) of proximal end optical module provides low and high level to generate representing fault investigation and ask
Seek the presence or absence of sequence light sequence.According to SFP modular electrical interface (INF-8074) agreement it is found that sending enable end (TX_
Disable) may be implemented shutdown emission function, high level or vacantly be it is effective, now using this pin function, generation is shaped like " having
Light-is unglazed, and-having light-unglazed-has light-unglazed, and-having light-unglazed-has light-unglazed-having light-unglazed-have light-it is unglazed-there is light-to have
The presence or absence of light " light sequence checks request sequence with this representing fault.
S102, remote equipment judge it is received have unglazed sequence for malfunction elimination request sequence after, proximally equipment reports
The running parameter sequence locally read, running parameter sequence have unglazed sequence to be corresponding with operating parameter values.
The optical module of remote equipment by it is received have it is unglazed Sequence Transformed at level signal sequence
