Migration of legacy Passive Optical Network (PON) to Next Generation PON (NG- PON) system is a must for broadband provider to survive in telecommunication competitive industry. Instead of the responsibility to cater the exhaustion of Malaysian's user to higher bandwidth, the financial impact to any Telco's account statement must be considered. Thus, the strategy to have lower capital expenditure (CAPEX) deployment cost is to be put as the highest priority consideration during the initial migration plan. The objective of this project is to compare migration strategy from GPON to NG-PON1 with GPON to NG-PON2 in term of CAPEX deployment cost for Telco in Malaysia. Another objective is to predict the cost effective migration scenario depending on the internet take up rate and bandwidth utilization. Objective of this project was achieved through collecting and analyzing data of CAPEX deployment cost for each of PON architecture. CAPEX deployment cost was generated using Davim and Pinto CAPEX cost model. In-depth data has also been collected by simulating the deployment of each PON architecture at small area with 320 homepass and urban areas 3447 number of homepass. In order to economically migrate the service, comparison between each topology has been discussed and assessed in term of cost of the components used. Migration of GPON to NG-PON1 has lower CAPEX deployment cost than migration from GPON to NG-PON2. The result of this project can be a basis strategy for any Telco to migrate from current Gigabit Passive Optical Network (GPON) system to Next Generation PON system.

AbstractIn time division, multiple access (TDMA)-based passive optical network (PONs), a dynamic bandwidth assignment (DBA) is necessary for efficient utilization of the available bandwidth of the upstream link. An efficient DBA scheme can improve the upstream performance of a traffic class of an ONU in two ways. First, it can increase the bandwidth assignment to it by efficiently utilizing the available bandwidth. Secondly, it can reduce the channel and frame idle time by increasing the polling frequency and by assigning extra surplus bandwidth not used by the other ONUs. Many DBA schemes have been reported for both ITU PONs (GPON and XGPON) and IEEE PONs (EPON and 10 G EPON). In this study, we explain the impact of DBA scheme on the upstream performance of PON and then do a thorough survey of both PON standards, categorize the DBA schemes and review them critically. Based on the literature review we also give our opinion on the most suitable DBA scheme for both type PONs on the basis of upstream delays, frame loss and bandwidth utilization efficiency.

AbstractNowadays, bandwidth demand is enormously increasing, that causes the existing passive optical network (PON) to become the future optical access network. In this paper, next generation passive optical network 2 (NG-PON2) based, optical time division multiplexing passive optical network (OTDM-PON), wavelength division multiplexing passive optical network (WDM-PON) and time & wavelength division multiplexing passive optical network (TWDM-PON) systems with 20 Gbps (8 × 2.5 Gbps) downstream and 20 Gbps (8 × 2.5 Gbps) upstream capacity for eight optical network units has been proposed. The performance has been compared by varying the input power (−6 to 27 dBm) and transmission distance (10–130 km) in terms of Q-factor and optical received power in the presence of fiber noise and non-linearities. It has been observed that TWDM-PON outperforms OTDM-PON and WDM-PON for high input power and data rate (20/20 Gbps). Also, TWDM-PON shows its superiority for long-reach transmission up to 130 km, which is a cost-effective solution for future NG-PON2 applications.
