Pasivno optično omrežje z gigabitno zmogljivostjo in bodoče optične dostopovne tehnologije

PODGORŠEK, NEJC (avtor), Batagelj, Boštjan (mentor)

Namen diplomskega dela je opis postopka vključitve gigabitnega pasivnega optičnega omrežja (angl. gigabit-capable passive optical network – GPON) na Savinjskem. Prav tako sta predstavljena topologija in delovanje omenjene optične tehnologije. Na kratko je opisan tudi novejši standard za naslednjo (drugo) generacijo pasivnega optičnega omrežja (angl. next-generation passive optical network stage 2 – NG-PON2), ki naj bi v bližnji prihodnosti nadomestil tehnologijo GPON. Metode dela pri postopku vključitve GPON so bile zelo raznolike, saj je ta naloga zahtevala združitev in uporabo mnogih znanj ter veščin s področja elektrotehnike in informacijsko-komunikacijskih tehnologij. Aktivacija sistema GPON je potekala sistematično, in sicer po pravilnem vrstnem redu. Najprej je bilo treba pripraviti prostor v lokalni centrali, nato je sledila postavitev potrebne infrastrukture, vključno z vsemi dodatnimi napravami, ki omogočajo delovanje dostopovnega omrežja. Priključiti je bilo treba tudi optične vrvice in nazadnje opraviti konfiguracijo sistema ter vse naprave vpisati v evidenco in omogočiti njihovo upravljanje na daljavo. Rezultat dela je popolnoma funkcionalno dostopovno optično omrežje, ki priključenim uporabnikom zagotavlja fiksno telefonijo, dostop do svetovnega spleta in televizije, ki temelji na internetnem protokolu (angl. internet protocol television – IPTV). Tovrstna omrežja so neprimerljivo boljša od bakrenih, saj so enostavno razširljiva in nudijo veliko večje zmogljivosti, hkrati pa so manj odporna na napake in omogočajo enostavnejšo implementacijo novih tehnologij.

Izvleček

The thesis addresses activation process of a gigabit-capable passive optical access network (GPON) in the Eastern Slovenia. Topology and operation principles of the said technology are presented as well. A new standard, called a next-generation passive optical network stage 2 (NG-PON2), which is scheduled to replace GPON in the future is also briefly described. Work methods for the activation of GPON were numerous and various, as this task demanded the use of many electrotechnical and information and communications technology (ICT) skills. The activation process of GPON was planned in advance and was performed systematically. Firstly, modifications of local exchange office were needed in order to implement the GPON technology. The installation of infrastructure came next which also included the additional devices that were added for the successful operation of the network. After that, optical fiber was connected and system configuration was performed. Additionally, all devices were registered in the archive and remote access was made possible. The result was completely functional optical access network which provides triple play service to its users. Those services include IPTV, broadband internet access and fixed telephony. Optical access networks are significantly better than their copper counterparts, as they are easily expandable and offer larger bandwidths. They are also less susceptible to interference and offer easier implementations of new technologies.
