Crosstalk analysis of an extended reach hybrid tree-ring PON architecture

Abstract

Passive optical network (PON) is the leading technology being used for delivering last-mile connectivity without any active components in the distribution network. In this paper, we focus on an un-amplified hybrid tree-ring PON architecture that carries the benefits of both the tree and the ring architectures. Through simulation, we demonstrate the optical performance of the system and focus on the physical layer performance impact of interchannel and intrachannel crosstalk due to non-ideal WDM multiplexers/demultiplexers and optical switches in the system.
