Auto ONU Fault Detection
If a certain ONU
’s laser is enabled consistently by an optical module’s fault, all other nor-
mal ONUs connected to the same OLT will be deregistered; a single ONU fault may
cause a whole network disruption.
Preventing such a problem, the V8102 provides the auto ONU (ONT) fault detection fea-
ture. Normally, if an ONU (ONT) fault occurs, a specific error signal is followed by the fault.
Thus, the V8102 validates whether an ONU (ONT) fault occurs by detecting the specific
error signal. The auto ONU fault detecting mechanism is as follows:
When detecting an error signal (an ONU fault) in a certain OLT, the V8102 generates a
corresponding syslog message, and then disables the laser of each ONU currently con-
nected to the OLT one by one for 60 seconds. At the moment that the faulty ONU
’s laser
is disabled, the error signal also disappears, then the system realizes that which the faulty
ONU is and memorizes its serial number. After 60 seconds, when the disconnected ONUs
(ONTs) start to enable their laser, if the ONU having the same serial number memorized
before tries to enable its laser, the V8102 disables the laser permanently. To resume the
laser, the ONU needs a power reset.
To enable/disable the auto ONU fault detection, use the following command.
