Unit is non-long hair light stream common people's optical network unit.The sending module 110 feeds back the non-long hair light stream common people to the optical line terminal 10
The alarm of optical network unit.
Wherein, in the interdiction countermeasure to non-long hair light stream common people's optical network unit, which, which sends, releases
Loopback information opens the light transmission link and light-receiving link of short circuit.This restarts the optical-fiber network list that module 123 is used to restart self-test
Member.
As the third self-detection result, optical network unit 100-1 is long hair light stream common people's optical network unit, is specially：When
When the difference of the feedback message and the self-test message is more than second threshold, represent between the feedback message and self-test message completely not
Accord with or have most of deviation, such as microprocessor 30 receives the data of feedback message always, that explanation 20 controlled hair of optical transceiver
Bag situation is very poor.The repair module 130 determines that the optical network unit is long hair light stream common people's optical network unit, the sending module 110
For feeding back the alarm of long hair light stream common people's optical network unit to the optical line terminal 10.
In the interdiction countermeasure to long hair light stream common people's optical network unit, which is used to cut off light receipts
Send out 20 power supplys of device；The reminding module 142 is used for the indicator light for opening long hair light stream common people's optical network unit.
The synchronization module 150 is set relative to the synchronization module 50 of the optical line terminal 10.The synchronization module 150 exists
When the optical line terminal 10 sends time synchronization information several times to the ONT Optical Network Terminal for sending alarm, in optical network unit side
The correction of time is synchronized, to reduce influence of rogue's optical network unit to passive optical network.
The optical transceiver of the present embodiment can recognize that the optical signal of 1310 nano wave lengths of processing.
Various feelings of the rogue's optical network unit detecting system of the passive optical network of the present embodiment to rogue's optical network unit
Condition can detect.For long hair light stream common people's optical network unit, the light transmission interface 22 of optical network unit optical transceiver from
Control, or it is controlled very poor, the power supply of the optical transceiver 20 of optical network unit is directly cut off for such case, avoids failure to it
Its optical network unit impacts, meanwhile, can in the equipment of optical network unit lightening LED lamp, such as display PON and LOS
It is bright at the same time, the fault cues to user's intuitively rogue's optical network unit.Rogue's optical-fiber network of the passive optical network of the present embodiment
Control chip unit detecting system takes corresponding interdiction countermeasure for various failures, for example allows for non-long hair light stream common people optical-fiber network list
Member, optical network unit are attempted self-recovery, if do not recovered, are just treated with long hair rogue's optical network unit, cut off optical-fiber network
The power supply of the optical transceiver of unit, makes it not influence other optical network units.
