Performance Evaluation of Symmetric and Asymmetric XG Passive Optical Networks

Abstract

The passive optical network refers to the optical network that configured without using any electrical components. XG-Passive optical Network (PON) is the first generation of the future optical network which is widely demands for transmitting massive information. This paper presented a design of XG-PON and evaluates the performance of XG-PON for both a single direction optical line and bidirectional optical line. The Paper discussed the basic structure and performance of symmetric and asymmetric XG-PON. The performance evaluations scope includes the measuring values of the bit error rate BER and the quality factor. The obtained results revealed that when using the same parameters the bidirectional design reflected better performance than single directional design and also proved that asymmetric XG-PON performance is better than symmetric one.
