  • Activation Process of ONU in EPON/GPON/XG-PON/NG-PON2 Networks 

    Horváth, Tomáš; Münster, Petr; Oujezský, Václav; Vojtěch, Josef (MDPI, 2018-10-16)
    This article presents a numerical implementation of the activation process for gigabit and 10 gigabit next generation and Ethernet passive optical networks. The specifications are completely different because GPON, XG-PON, ...
  • Distributed Sensing Based on Interferometry and Polarization Methods for Use in Fibre Infrastructure Protection 

    Münster, Petr; Horváth, Tomáš; Vojtěch, Josef (MDPI, 2019-04-16)
    Fibre optic infrastructures are very important, and therefore, it is necessary to protect them from fibre cuts. Most fibre cuts are caused by digging activity, and many network operators seek appropriate solutions enabling ...
  • Joint accurate time and stable frequency distribution infrastructure sharing fiber footprint with research network 

    Vojtěch, Josef; Šlapák, Martin; Škoda, Pavel; Radil, Jan; Havliš, Ondřej; Altmann, Michal; Münster, Petr; Velc, Radek; Kundrát, Jan; Altmannová, Lada; Vohnout, Rudolf; Horváth, Tomáš; Hůla, Miloslav; Smotlacha, Vladimír; Čížek, Martin; Pravdová, Lenka; Řeřucha, Šimon; Hrabina, Jan; Číp, Ondřej (SPIE, 2017-02-07)
    The infrastructure essentialities for accurate time and stable frequency distribution are presented. Our solution is based on sharing fibers for a research and educational network carrying live data traffic with time and ...
  • Modified GIANT Dynamic Bandwidth Allocation Algorithm of NG-PON 

    Horváth, Tomáš; Oujezský, Václav; Münster, Petr; Vojtěch, Josef; Havliš, Ondřej; Sikora, Pavel (Croatian Communications and Information Society, 2017-04-07)
    As NS-3 simulator does not support the direct mapping of Triple Play services into T-CONT and their labeling. We focus on a delay value for Triple Play services which was reduced by own modification in a GIANT algorithm. ...
  • Simultaneous Transmission of Photonic Services over One Fiber with an ITU 100 GHz Grid 

    Horváth, Tomáš; Münster, Petr; Vojtěch, Josef; Smotlacha, Vladimír (MDPI, 2019-04-02)
    The increasing interest in distributed sensors and the decreasing price of optical components have led to leveraging the use of existing fiber in deployments over optical networks and more application possibilities (from ...
  • Transmission of high power sensor system and DWDM data system in one optical fiber 

    Čučka, Milan; Münster, Petr; Kočí, Lukáš; Horváth, Tomáš; Filka, Miloslav; Vojtěch, Josef (Croatian Communications and Information Society, 2016-12-01)
    The main contribution of this paper is simulation of transmission DWDM system and high power sensor system in one optical fiber
