  • 28. Ranging OLT obtains the Round Trip Delay (RTD) through ranging process, then specifies suitable Equalization Delay (EqD) so as to avoid occurrence of collision on optical splitters. To acquire the serial number and ranging, OLT needs open a window, that is, Quiet Zone, and pauses upstream transmitting channels on other ONUs.

  • 29. DBA What is DBA? DBA, Dynamic Bandwidth Assignment Why DBA? It enhances the uplink bandwidth utilization of PON ports. More users can be added on a PON port. Users can enjoy higher-bandwidth services, especially those requiring comparatively greater change in terms of the bandwidth.

  • 30. SR-DBA Operation OLT ONU DBA report DBA algorithm logic Control platform BW Map Data platform T-CONT Time slot T-CONT Scheduler T-CONT DBA block in the OLT constantly collects information from DBA reports, and sends the algorithm result in the form of BW Map to ONUs . Based on the BW Map, each ONU sends upstream burst data on time slots specified to themselves and utilizes the upstream bandwidth.HUAWEI TECHNOLOGIESTechnologies Co., Ltd. Huawei Confidential Copyright © 2006 Huawei CO., LTD. All rights reserved. Page30 30 Page
  • 31. SR-DBA Operation D/S Direction ONTOLT ① Based on the algorithm result of PCBd US BW Payload Map last time, OLT delivers BW Maps in the header of downstream frames. ② U/S Direction Data Report Based on the bandwidth allocation information, ONU sends the status report of data currently waiting in T-CONTs in the specified time ③ slots. OLT receives the status report from the ONU, updates BW Map through DBA algorithm and then delivers the new BW Map in the next frame. ④ ONU receives the BW Map from the OLT and sends data in the specified time slots.HUAWEI TECHNOLOGIESTechnologies Co., Ltd. Huawei Confidential Copyright © 2006 Huawei CO., LTD. All rights reserved. Page31 31 Page
  • 32. NSR-DBA Operation NSR-DBA NSR is an algorithm scheme that realizes DBA. It helps to predict the bandwidth allocated to each ONU based on the traffic from ONUs. Procedure: Step1: Monitor the number of data packets received by OLT within the specified interval. Step2: Use the result of real time monitoring in step 1 to calculate the utilization rate. Step3: Recognize the congestion status by comparing the utilization rate with the specified limits.HUAWEI TECHNOLOGIESTechnologies Co., Ltd. Huawei Confidential Copyright © 2006 Huawei CO., LTD. All rights reserved. Page32 32 Page
  • 33. DBA Working Principle Based on service priorities, the system sets SLA for each ONU, restricting service bandwidth. The maximum bandwidth and the minimum bandwidth pose limits to the bandwidth of each ONU, ensuring various bandwidth for services of different priorities. In general, voice service enjoys the highest, then video service and data service the lowest in terms of service priority. OLT grants bandwidth based on services, SLA and the actual condition of the ONU. Services of higher priority enjoy higher bandwidth.HUAWEI TECHNOLOGIESTechnologies Co., Ltd. Huawei Confidential Copyright © 2006 Huawei CO., LTD. All rights reserved. Page33 33 Page
  • 34. T-CONT Bandwidth Terms Transmission Containers (T-CONTs): it dynamically receives grants delivered by OLT. T-CONTs are used for the management of upstream bandwidth allocation in the PON section of the Transmission Convergence layer. T-CONTs are primarily used to improve the upstream bandwidth use on the PON. T-CONT BW type falls into FB, AB, NAB, and BE. Five T-CONT types: Type1, Type2, Type3, Type4, and Type5.HUAWEI TECHNOLOGIESTechnologies Co., Ltd. Huawei Confidential Copyright © 2006 Huawei CO., LTD. All rights reserved. Page34 34 Page
  • 35. T-CONT Type and Bandwidth Type Type1 T-CONT is of the fixed bandwidth type and mainly used for services sensitive to delay and services of higher priorities, such as voice services. Type2 and type3 T-CONT is of the guaranteed bandwidth type and mainly used for video services and data services of higher priorities. Type4 is of the best-effort type and mainly used for data services (such as Internet and email), and services of lower priorities. These services do not require high bandwidth. Type5 is of the mixed T-CONT type, involving all bandwidth types and bearing all services.HUAWEI TECHNOLOGIESTechnologies Co., Ltd. Huawei Confidential Copyright © 2006 Huawei CO., LTD.

  • 39. Fibre Attenuation and Power Budget Fibre attenuation relates to the fibre length About 0.35 dB per km The attenuation of fibre splicing point is for 1310,1490nm generally less than 0.2dB Other factors may cause attenuation, such as fibre bending Huawei’s OLT and ONU 28 dB (Class B+) Table G.984.2 – Classes for optical path loss Class A Class B Class Class C + B+ Minimum loss 5 dB 10 dB 13 dB 15 dB Maximum loss 20 dB 25 dB 28 dB 30 dB NOTE – The requirements of a particular class may be more stringent for one system type than for another, e.g. the class C attenuation range is inherently more stringent for TCM systems due to the use of a 1:2 splitter/combiner at each side of the ODN, each having a loss of about 3 dB.HUAWEI TECHNOLOGIESTechnologies Co., Ltd.

  • 43. GPON Management OAM message at the physical layer falls into three types: embedded OAM, PLOAM and OMCI . The embedded OAM and PLOAM channels manage the functions of the PMD and the GTC layers. The OMCI provides a uniform system of managing higher (service defining) layers. The embedded OAM channel is provided by field-formatted information (such as BW Map,DBRu) in the header of the GTC frame. The functions that use this channel include: bandwidth granting, Dynamic Bandwidth Assignment signalling and so on. The OMCI channel is used to manage the service defining layers that lay above the GTC.HUAWEI TECHNOLOGIESTechnologies Co., Ltd. Huawei Confidential Copyright © 2006 Huawei CO., LTD.
