Simulation of Downlink of 10G-PON FTTH in the city of Košice

Abstract

Optical fiber has the great advantages of capacity and reliability. That is why network providers started to deploy FTTx (Fiber-To-The-x) optical access using various PON (Passive Optical Network) architectures. The leading technology right now is Gigabit PON (GPON). However, with increasing amount of multimedia we need to further develop existing technologies to go on with these high demands. Fiber-To-The-Home (FTTH) using 10G-PON technology for broadband access application is effective solution for high speed networks with high capacity. In this paper, we look at the passive optical network in the city of Košice and based on the real network we created simulation model of downlink of 10G-PON based FTTH with triple-play service.

Performance analysis of long‐reach 40/40 Gbps mode division multiplexing‐based hybrid time and wavelength division multiplexing passive optical network/free‐space optics using Gamma‐Gamma fading model with pointing error under different weather conditions

“…In addition, nonreturn to zero OOK (NRZ-OOK) modulation is regarded as an industry standard for several optical fiber communication systems. Using OOK modulation for the bidirectional hybrid PON/FSO system can support several users over a fiber and FSO link range of 25 km and 200 m. 27,28 Mode division multiplexing (MDM) is an innovative inexpensive data transmission technique applying which multiple signals can be transferred synchronously on multiple modes of single-frequency laser-generated utilizing single-mode fiber, spatial light modulator, and optical signal processing. 29,30 Grover et al, 31 reports the simulations to investigate the reliable transmission of 40 Gbps information over 90 km FSO link incorporating polarization shift keying based MDM-FSO system under clear atmospheric conditions' effect using Laguerre Gaussian (LG) modes.…”

Development of Multicast Service Technical Requirements Regulation on Xg-Pon Olt Equipment

“…PON represents the optical distribution network (ODN) between the Optical Line Termination (OLT) and the Optical Network Unit (ONU). PON does not contain active electronic devices but instead uses an optical connector and splitter to direct individual wavelength signals to end-users (Huszaník et al, 2018). One PON technology that promises to provide quality service for its users is the 10-gigabit-capable PON (XG-PON) technology.…”
