| 20120087649 | Method and system for instructing enabling/disabling forward error correction coding function - The present invention discloses a method for instructing enabling/disabling Forward Error Correction (FEC) function. The method comprises: presetting an instruction identifier of an FEC status; transmitting an instruction identifier of an FEC status of an Optical Network Unit (ONU) and the Identity (ID) of the ONU by an Optical Line Terminal (OLT), wherein the instruction identifier of the FEC status of the ONU is corresponding to the ID of the ONU; and enabling or disabling its own FEC function by the ONU according to the received instruction identifier corresponding to its own ID. The present invention also discloses a system for instructing enabling/disabling FEC function, which comprises an OLT and an ONU. The method and system of the present invention can solve the problem that the ONU cannot determine the instruction from the OLT due to an error code. | 04-12-2012 |
| 20120114333 | Method and System for Quickly Updating Ranging Results of Optical Network Unit by Optical Line Terminal - The disclosure provides a method for quickly updating ranging results of optical network units by an optical line terminal. The method comprises the following steps: an Optical Line Terminal (OLT) distributes an acquired ranging difference to all the Optical Network Units (ONUs); and the current ONU implements quick updating of the ranging result of the current ONU itself according to the acquired ranging difference. The disclosure also provides a system for quickly updating ranging results of ONUs by an OLT, wherein a distributing unit in the OLT is used for distributing an acquired ranging difference to all the ONUs; an updating unit in the ONU is used for implementing quick updating of ranging result of the current ONU itself according to the acquired ranging difference. the method and system of the disclosure can save the quantity of messages, enable quick switching in protection status, thus implementing protection switching efficiently. | 05-10-2012 |
| 20120237216 | METHOD FOR TRANSMITTING DATA AND GIGABIT-CAPABLE PASSIVE OPTICAL NETWORK SYSTEM - The present invention discloses a method for transmitting data and a gigabit-capable passive optical network system, which method comprises: a transmitter carrying indication information in an uplink or a downlink frame transmitted to a receiver for enabling the receiver to discard information which does not need to be processed by the receiver in the uplink or downlink frame according to the indication information. The data type transmitted by GPON systems is expanded and the idle bandwidth is effectively handled by the present invention. | 09-20-2012 |

| 20120121253 | RANGING METHOD AND APPARATUS IN PASSIVE OPTICAL NETWORK - The present invention discloses a method for ranging in a passive optical network, and the method includes: obtaining a Round Trip Delay (RTD) between an Optical Line Terminal (OLT) and an Optical Network Unit (ONU); and opening a quiet window used for the ranging for the ONU according to the RTD to perform the ranging on this ONU. The present invention further discloses an apparatus for ranging in a passive optical network, and the apparatus includes: an obtainment module which is configured to: obtain a RTD between an OLT and an ONU; and a ranging module configured to: open a quiet window used for ranging for the ONU to perform ranging on the ONU according to the RTD. The present invention shortens the open time of the quiet window used for the ranging and improves the efficiency of the upstream transmission, and the implementation method is simple and convenient. | 05-17-2012 |
| 20120213509 | Method and Passive Optical Network System for Managing Uplink Burst Overhead Parameters - A method for managing upstream burst overhead parameters includes: an Optical Line Terminal (OLT) or an Optical Network Unit (ONU) detects transmission quality of a downlink between the OLT and the ONU; the OLT or the ONU determines the upstream burst overhead parameters suitable for the ONU according to the transmission quality; and the ONU starts to use the upstream burst overhead parameters suitable for the ONU after the switching time determined by the ONU itself or indicated by the OLT. The present invention also provides an ONU and an OLT for managing the upstream burst overhead parameters. The present invention can improve the bandwidth utilization rate and decrease the complexity of indicating the upstream burst overhead parameters in PON system, so that the ONU and the OLT are enabled to flexibly and simply select the upstream burst overhead parameters. | 08-23-2012 |
