Evaluation of the Effect of Fiber optic Dispersion on a(XGPON)Next Generation passive optical network
Journal Title: IOSR Journal of Electronics and Communication Engineering(IOSR-JECE) - Year 2018, Vol 13, Issue 6
Abstract
The next generation passive optical network requires a network that can provide high capacity data to meet the increase rate for high speed data. The fiber optic media has low susceptibility to electromagnetic interference hence become a choice for high capacity network. The next generation passive optical network (NGPON) stage 1 defined and standardized by ITU-T, adopted 10G passive optical network (XGPON) has one of the standard capable of meeting the demand. This standard will be used for deployment of high capacity broadband networksand mobile backhaul which will enhance high speed connectivity. This architecture is not immune to loses or signal degradation due to dispersion (chromaticdispersion(CD) and Polarization mode dispersion (PMD)) which causes the signal to degrade as it travels over the fiber length due to pulse broadening. This paper investigates the effect of dispersion on an XGPON in order to provide a guide during practical deployment and suggest maximum bit rate that can be achieved at shorter distances of less than 10Km which is commonly found on metropolitan area. Amodel was setup using Optisystem simulator to observe the effect of dispersion on thearchitecture and also to obtain the maximum bit rate that can be achieved at shorter fiber length. The result obtained suggests that in the presence of dispersion XGPON can reach a maximum distance of 72Km within the acceptable bite error rate (BER) of 10-9 anda maximum bit rate of 27.5 Gigabit per seconds (Gb/s)at a distance of less than 10Km.
