GPON in Telecommunication Network

this paper GPON in Telecommunication Network, will present GPON in a relation to NG Network, and try to show that Gigabit Passive Optical Networks are very economical, effective, and reliable solution for triple play service. Also, the paper shows GPON as technically and economical sound solution for Next Generation Network. It will present details about GPON applications such as: GPON ONU as Uplink, GPON as metro net, multi-user per one GPON ONU, GPON as FTTH/B, and etc. Also paper will mention mechanisms that are used for implementing GPON applications such as: DBA algorithm (algorithm for control of upstream speed), GEM (inner transmit method), protection schemes, and control of download speed as additional feature that is not included in the default GPON settings. Briefly paper will look at other elements of GPON such aggregation switch; voice service: V.5.2, SIP and H.248. Economic aspect of projects and/or solutions in telecommunication networks is very important factor, GPON is no exception. So the paper will try to present both economical and technical aspects of GPON in relation to telecommunication network, and other similar solution that are currently available.
