GPON Triple Play and SDH Connectivity Structure with Cost Analysis

The rapid growth of bandwidth requirements for services like IP television and video on demand over Internet together with high speed Internet access have demand for very high bandwidth to customers as well as the changing role of enterprise networking are causing disruptive change in the enterprise local area networks. The most suitable solution for satisfying the high bandwidth demand with a long reach is using optical cable to customers through gigabit passive optical network (GPON) technology. In the last one decade many research work has been carried out on network architecture, transmission mechanisms, power budget, bandwidth allocation and scalability of GPON technology. But to tape the full potential of GPON and extends its last mile limit, there is no detail analysis regarding the convergence of synchronous digital hierarchy (SDH) connectivity as well as which particular wavelength should be optimum for transmission. In this paper a new enhanced GPON architecture is proposed incorporating SDH transmission at optimum wavelength.
