Ethernet Passive Optical Network (EPON) is a promising solution for access network. In this paper, we propose an enhanced Sharing DBA algorithm (SDBA) that supports multiple priority queues and fairness among optical network units (ONUs) over upstream EPON. We conduct simulation using MATLAB to study the performance and validate the effectiveness of the… (More)
The " last mile " bandwidth bottleneck problem can be best solved by using Ethernet Passive Optical Network (EPON). EPON is a promising technology to implement the Fiber To The Home solution. Dynamic bandwidth allocation (DBA) is one of the critical issues in the design of the EPON system that has been studied by many researches. This paper introduces the… (More)

A new approach to suppressing the four-wave mixing (FWM) crosstalk by using the pairing combinations of differently linear-polarized optical signals was investigated. The simulation was conducted using a four-channel system, and the total data rate was 40 Gb/s. A comparative study on the suppression of FWM for existing and suggested techniques was conducted… (More)
In order to accommodate the needs of very high-speed broadband access, the most attractive solution that is being used nowadays is Ethernet passive optical network (EPON). In upstream EPON, dynamic bandwidth allocation (DBA) algorithm is needed to avoid collision. By ensuring global priority inside DBA, bandwidth can be better utilized since we grant the… (More)
