Detailed Description
The core of the invention is to provide a method and a device for reporting a received signal loss alarm by an optical module, which are used for preventing a QSFP28 optical module from mistakenly carrying out the received signal loss alarm.
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Fig. 1 is a flowchart of a method for reporting a received signal loss alarm by an optical module according to a first embodiment of the present invention. As shown in fig. 1, the method for reporting a received signal loss alarm by an optical module includes:
s10: when an INTRPT-RX pin of an internal chip of the optical module is detected to output an alarm state, an RX _ LOS state bit of an RX _ LOS register of the optical module is read.
S11: judging whether the RX _ LOS status bit is in an alarm state; if not, the flow proceeds to step S12.
S12: and controlling the INTL pin of the optical module to output a normal state.
It should be noted that the alarm state and the normal state of each pin described in this application may be a high level or a low level, respectively, and may be set when the circuit is connected and programmed, which is not limited in this application. Similarly, the alarm state and the normal state of the status bit of each register in the application can be set by the user.
Because the QSFP28 optical module has no output pin for receiving signal LOSs alarm RX _ LOS, when the optical module has RX _ LOS state, the low level is reported through the INTL pin, which indicates the state of receiving signal LOSs. However, in practical applications, when the receiving chip of the optical module receives an optical signal that is not sent to the modulation signal, the receiving chip may also trigger the INTL pin to report a state of loss of the received signal, and a received signal loss alarm may be erroneously performed without signal loss.
Therefore, in the embodiment of the invention, the INTRPT-RX pin of the internal chip of the optical module, the I2C pin and the INTL pin of the external output are respectively connected with the MCU chip. Meanwhile, the MCU chip reads the RX _ LOS status bit of the RX _ LOS register in the communication process with the chip. The MCU chip detects the level value output by the INTRPT-RX pin, when the output of the INTRPT-RX pin is in an alarm state, the fact that a received signal abnormal phenomenon possibly exists is indicated, whether the RX _ LOS state bit of the RX _ LOS register is in the alarm state or not is checked, if not, the RX _ LOS phenomenon does not occur to the optical module, and the fact that a received signal LOSs alarm does not need to be reported is judged.
Further, when the level value of the INTRPT-RX pin is detected to be in an alarm state, the method may further include:
and recording the alarm information of the INTRPT-RX pin.
In a specific implementation, the information may include the occurrence time of the INTRPT-RX pin alarm, and is stored in combination with a signal generation log output by the MCU chip from each signal output pin of the optical module, so that a subsequent user may count and summarize abnormal signals in the optical module.
The method for reporting the received signal LOSs alarm by the optical module provided by the embodiment of the invention does not directly use the level value of the INTL pin of the optical module as the basis for reporting the received signal LOSs alarm, but reads the RX _ LOS state bit of the RX _ LOS register of the optical module when detecting that the INTRPT-RX pin of the internal chip of the optical module outputs the alarm state, and judges whether the RX _ LOS state bit is in the alarm state or not; if not, the INTL pin of the optical module is controlled to output a normal state, and compared with the prior art that the RX _ LOS of the optical module is judged only by outputting a low level through the INTL pin, the receiving signal LOSs alarm is avoided when the RX _ LOS state of the optical module does not occur, and unnecessary misjudgment of the system is prevented.
Fig. 2 is a flowchart of a method for reporting a received signal loss alarm by a second optical module according to an embodiment of the present invention. As shown in fig. 2, on the basis of the foregoing embodiment, in another embodiment, when the determination result of step S11 is that the RX _ LOS status bit is in an alarm state, the method further includes:
s20: and reading the RX CDR status bit of the RX CDR status bit register of the optical module.
S21: judging whether the RX CDR status bit is in an alarm state; if not, the flow proceeds to step S22.
S22: and controlling the INTL pin to output an alarm state to report a received signal loss alarm.
In the above embodiment, when the RX _ LOS status bit of the RX _ LOS register is in an alarm state, it indicates that the optical module is likely to have an RX _ LOS phenomenon, and a LOSs of received signal alarm needs to be reported, so that the MCU chip can directly control the INTL pin to report the LOSs of received signal alarm. However, the RX LOS status bit of the RX LOS register is in an alarm state, and may also be caused by an RX CDR status bit register alarm. To further reduce the likelihood of false positives, further verification may be performed.
In practical application, the MCU chip communicates with the internal chip of the optical module via I2C, from which the MCU chip reads the RX CDR status bit of the RX CDR status bit register. When the RX _ LOS status bit is in an alarm state, the RX CDR status bit is read, when the RX CDR status bit is in a normal state, the RX CDR does not alarm, the RX _ LOS status bit is caused by an RX _ LOS phenomenon in the alarm state, and at the moment, the MCU chip controls the INTL pin to output the alarm state to report the LOSs of signal receiving alarm.
The method for reporting the LOSs alarm of the received signal by the optical module provided by the embodiment of the invention further reduces the possibility of misjudging the RX _ LOS phenomenon and reporting the LOSs alarm of the received signal by mistake by eliminating the possibility that the RX _ LOS state bit is in the alarm state caused by the alarm state output by the RX CDR state bit.
Fig. 3 is a flowchart of a method for reporting a received signal loss alarm by a third optical module according to an embodiment of the present invention. As shown in fig. 3, on the basis of the foregoing embodiment, in another embodiment, when the determination result of step S21 is that the RX CDR status bit is in the alarm state, the method further includes:
s30: and reading the RSSI value of the optical module.
S31: judging whether an ADC value obtained by RSSI value conversion is larger than a preset value or not; if so, go to step S12; if not, the flow proceeds to step S22.
In the above embodiment, when the RX CDR status bit is in the alarm state, it indicates that the RX _ LOS status bit is in the alarm state, which may be caused by the RX _ LOS phenomenon or the RX CDR alarm, and only when the RX _ LOS status bit appears, the RX _ LOS status bit does not need to report the LOSs of received signal alarm. In order to further reduce the possibility of erroneous determination, the added verification in the embodiment of the present invention may be performed, that is, whether the optical signal received by the optical module is really lost is determined according to the RSSI ADC value of the optical module.
In practical application, the MCU chip communicates with the internal chip of the optical module via I2C, and reads the RSSI value output from the RSSI pin. The threshold value, i.e., the preset value, of the optical signal satisfying the requirement is stored in the MCU chip in advance. When the RX _ LOS status bit is in an alarm state and the RX CDR status bit is also in an alarm state, it cannot be determined what cause the RX _ LOS is, and further it cannot be determined whether the RX _ LOS phenomenon occurs, the RX _ LOS phenomenon is determined by the generation source, i.e., the optical signal LOSs. After the RSSI value output by the RSSI pin of the MCU chip is converted to obtain the RSSI ADC value, the MCU chip determines whether the RSSI ADC value is greater than a preset value stored in the MCU chip, if so, it indicates that the received optical signal is sufficient and no RX _ LOS phenomenon occurs, so step S12 is performed without reporting a LOSs of received signal alarm, otherwise, it goes to step S22 to report a LOSs of received signal alarm.
The method for reporting the received signal LOSs alarm by the optical module provided by the embodiment of the invention can judge whether the optical signal received by the optical module reaches the alarm threshold from the root by checking the RSSI value output by the optical module when the possibility that the RX _ LOS state bit is in the alarm state caused by the alarm state output by the RX CDR state bit cannot be eliminated, thereby further reducing the possibility of misjudging the RX _ LOS phenomenon and reporting the received signal LOSs alarm by mistake.
Fig. 4 is a flowchart of a method for reporting a received signal loss alarm by a fourth optical module according to an embodiment of the present invention. As shown in fig. 4, on the basis of the foregoing embodiment, in another embodiment, the method for reporting a received signal loss alarm by an optical module further includes:
s40: and receiving a preset value set by a user.
In practical application, the preset value, i.e. the alarm threshold of the optical signal, may be stored in the MCU chip in advance, or may be adjusted during the operation of the optical module. And the input device is connected with the MCU chip in advance for a user to input a preset value so as to adapt to the requirements of the optical module in different occasions.
On the basis of the above detailed description of the embodiments corresponding to the method for reporting the received signal loss alarm by the optical module, the present invention also discloses a device for reporting the received signal loss alarm by the optical module corresponding to the above method.
