RANGING METHOD FOR PASSIVE OPTICAL NETWORK, SYSTEM, AND DEVICE |
摘要 |
Embodiments of the present invention provide a ranging method for a passive optical network, comprising: allocating ranging bandwidths to at least two optical network terminations (ONTs), and providing ranging bandwidth information for the at least two ONTs through the same downlink frame; opening a silent window for suspending uplink transmission of other ONTs in the ranging process of the at least two ONTs; and receiving ranging replies of the at least two ONTs in the silent window, and according to the ranging replies of the at least two ONTs, calculating a ranging result of the at least two ONTs. The embodiments of the present invention further provide a ranging device for a passive optical network and a passive optical network system. |
