Block).
Following table 1 is the configuration of OAM protocol frame and field description example:
Table 1
In one embodiment, normal ONU and the luminous exception ONU of duration are shown using what fixed test time slot was diagnosed
It is intended to as shown in figure 11.
The top half of Figure 11 is normal ONU state diagram when carrying out abnormal luminous detection.
According to the ONU that Optical Transmitteer id field is detected in OAM protocol frame, OLT requirement is being received
After the OAM protocol frame for carrying out abnormal luminous detection, abnormal luminous ONU detection acknowledgement frame is returned, time slot detection is then fixed.
ONU optical module transmitter sends Report frame information, by a free timeslot, according still further to OAM agreement according to the requirement of OLT
The instruction of frame Action field carries out suspend mode.The duration of the suspend mode can be for less than 1s.Pass through a free timeslot later, again
Send Report frame information.Repeatedly, until the Report frame number of transmission reaches the predetermined number of times of OAM protocol frame, i.e. table 1
The specified number of middle Number field.
The lower half portion of Figure 11 is when carrying out abnormal luminous detection, and duration shines exception ONU state diagram.
After OLT sends OAM protocol frame to the ONU for carrying out abnormal luminous detection, it is true that ONU does not return to abnormal luminous ONU detection
Recognize frame, does not also carry out Report frame according to the instruction of OAM protocol frame and send and optical module suspend mode.
Based on above difference, the optical power by detecting free timeslot can distinguish that duration shines exception ONU.Pass through
The Number number whether the Report frame number that statistics ONU is sent requires with OAM protocol frame matches, and can more accurately judge
Whether ONU state is abnormal, to carry out the detection of abnormal luminous ONU under the premise of without hardware modification.
In one embodiment, schematic diagram such as Figure 12 institute that the luminous ONU of intermittence uses fixed test time slot to be diagnosed
Show.
The top half of Figure 12 is in intermittent luminous exception ONU diagnosis, and the ONU state of efficient diagnosis, lower half portion is
The ONU state diagnosed in vain.
OLT specifies one group of ONU (ONU1, ONU2 ... ONUn) to be detected by OAM protocol frame.It is designated for detecting
Multiple ONU return to abnormal luminous ONU and detect acknowledgement frame.The optical module transmitter of appointed ONU according to OLT requirement and point
The time slot matched sends Report frame information, by a free timeslot, according still further to OAM protocol frame Action field instruction into
Row suspend mode.The duration of the suspend mode can be for less than 1s.Pass through a free timeslot later, sends Report frame information again.Such as
This repeatedly, until Report frame number that all specified ONU are sent reaches the predetermined number of times of OAM protocol frame, i.e., in table 1
The specified number of Number field.In fixed test time slot, the bit error rate is detected.
If detecting, the bit error rate rises, and illustrates have other ONU to shine other than the ONU of specified detection, i.e., intermittent hair
Light exception ONU is not among the ONU of the specified detection of OAM agreement.It is therefore intended that ONU be normal luminous ONU, these ONU are added
It is added to normal luminous ONU list, for excluding normal luminous ONU.
If bit error rate rising is not detected, specification exception shines ONU in specified ONU, fails to intermittent hair
Light is abnormal, and specified ONU cannot be added to normal luminous ONU list, needs to reassign ONU and carries out abnormal luminous diagnosis.
By such method, normal luminous ONU can be gradually excluded, thus under the premise of without hardware modification,
The diagnosis of abnormal luminous ONU is carried out, determines intermittent luminous exception ONU.
