Využití optických zesilovačů v sítích NG-PON2

Abstract

The aim of the thesis was to introduce the standard ITU-T G.989. Introduction deals with passive network architecture, which clarifies the basic functional elements that occur in optical networks. Been described active components and the very principle of data transfer in the distribution network. Next section is devoted to new technologies that are defined for the latest generation of passive networks NG-PON2. There have been a principle of data transmission in such networks and their advantages and disadvantages. I described the principle of data transmission in such networks and their advantages and disadvantages. The practical part deals with creating a functional network of NG-PON2 also using optical amplifiers. Another suggestion was using a digital CATV transmission of QAM modulation under optical networks on a dedicated wavelength of 1550 nm. Also simulate the coexistence of this new standard with previous PON technologies. Finally, the work consisted in implementing the Miller’s code into OptSim v5.2 environment, which compared the transmission characteristics of each line of codes with this Miller’s code. All practical simulations were designed and simulated in program OptSim v5.2.

Cieľom diplomovej práce bolo predstaviť štandard ITU-T G.989. Úvod sa zaoberá architektúrou pasívnych sieťí, kde sú objasnené základné funkčné prvky, ktoré sa v optických sieťach vyskytujú. Boli opísané aktívné prvky a samotný princíp prenosu dát v distribučnej sieti. Ďalšia časť sa venovala novým technológiám, ktoré sú definované pre poslednú generáciu pasívnych sietí NG-PON2. Bol popísaný princíp prenosu dát v týchto sieťach a ich výhody a nevýhody. Praktická časť sa zaoberá vytvorením funkčnej siete NG-PON2 aj s využitím optických zosilňovačov. Nasledujúci návrh predstavoval prenos CATV pomocou digitálnej QAM modulácie v rámci optických sietí na vyhradenej vlnovej dĺžke 1550 nm. Taktiež sa simulovala koexistencia tohto nového štandardu s predchádzajúcimi technológiami PON. Záver práce pozostával v implementovaní Millerovho kódu do prostredia OptSim v5.2, v ktorom sa porovnávali prenosové vlastnosti jednotlivých linkových kódov s týmto Millerovým kódom. Všetky praktické simulácie boli navrhnuté a odsimulované v programe OptSim v5.2.
