ABSTRACT - Today's telecommunication trends are requesting higher and higher broadband access speeds. Operators are facing with stronger competition, need to introduce new services and constant battle to reduce costs. Cable networks were primarily designed for distribution of TV signal. Today they are facing a challenge how to upgrade them to be ready for future demands. DOCSIS 3.1 is an evolutional upgrade that is requesting a serious investment into the network. It make sense to propose more bold solution of migration to complete fibre network. The author will present advantages of GPON technology versus DOCSIS 3.1 and the process of network migration.

POVZETEK - Današnji trendi v telekomunikacijah kažejo potrebe po zviševanju dostopovnih hitrosti v dostopnih omrežjih. Na drugi strani se operaterji soočajo z vse večjo konkurenco, potrebami po uvajanju novih storitev in nižanju stroškov. Kabelska omrežja, ki so bila v osnovi zasnovana za prenos televizijskega signala so se znašla pred dilemo, kako jih je možno na čim bolj učinkovit način nadgraditi za trenutne in bodoče potrebe. DOCSIS 3.1 je evolucijska nadgradnja, ki zahteva precejšnje investicije v omrežje, zato se je smiselno vprašati o bolj drzni nadgradnji na popolno optično omrežje. Avtor bo predstavil prednosti tehnologije GPON v primerjavi z DOCSIS 3.1 in postopek nadgradnje omrežja.
