Presents the introductory welcome message from the conference proceedings. May include the conference officers' congratulations to all involved with the conference event and publication of the proceedings record.
Recent dramatic advance of information and communication technologies has yielded new environments around us. However, its penetration differs area by area. For the realization of a future broadband environment that everyone can enjoy everywhere, several technical issues have to be resolved before networks can be migrated. One such key is the use of fiber-optics in the home and for mobile services...
The Slovenian fiber-to-the-home (FTTH) market is an interesting case, since Slovenia has a high level of FTTH deployment, intense infrastructure competition in urban areas and regulated access to FTTH networks. In this paper, the FTTH access solutions that are implemented in the Slovenian telecommunications market are reviewed. Before the economic crisis, in 2009, the two main Slovenian telecommunications...
The study about a cost effective topology based on the single wavelength bi-directional multiplex is conducted. In this study the Capital Expenditure (CAPEX) from point of view of payback period is analyzed, and a cost-effective novel FTTH (Fiber to the Home) scheme based on the single wavelength bidirectional multiplex is proposed. By using the proposed schema it is possible to reduce initial CAPEX...
In current study, the two dimensional spectral amplitude coding and polarization division multiplexing-based optical code division multiple access (2D SAC/PDM-based OCDMA) is proposed to transmit the optical coded and polarized signal over wireless transmission channel. The multiple access interference (MAI) cancellation is investigated to further prove the possible transmission of proposed scheme...
A short range visible light communication system based on the use of RGB-based LEDs which can potentially to perform multi-wavelength transmission was experimentally implemented and is presented in this paper. The performance of an equalized receiver with broadband optical filters capable of receiving multiple optical wavelengths transmitted from RGB-based LEDs was experimentally evaluated under different...
For the practical implementation of wavelength-division multiplexed passive optical networks, low-cost communication light sources are crucial. One of the possible ways to achieve a low-cost colorless optical network unit with seeding light requires the use of an injection-locked Fabry-Perot laser diode. We experimentally investigate the frequency response of an injection-locked Fabry-Perot laser...
The implementation of a freeform lens at the end of an optical fiber delivery line is an attractive method to make efficient use of the rapidly expanding light-emitting diode technology for illumination applications. Of particular interest for intelligent homes and extended smart lighting system usage is the design of a freeform lens for creating a uniform illumination pattern with various shapes...
The guiding properties of Bragg gratings inscribed in solid core photonic crystal fibers (PCFs) are investigated theoretically using a full vectorial Multipole Method combined with closed form expressions for the reflection response of the Bragg fiber gratings. When the PCF air-holes are infiltrated with different fluids, a downward shift is observed in the power reflectivity spectra. Both relative...
Optical networks with tuned architecture intending to internetworking with Ethernet connection and possessing improved resistivity to unfavorable external influences are considered. The main operation principle is using of a photoelectrical supply mode for Ethernet RJ45 to Fiber Optic Media Converter. An offered schematic can involve as electro-optical converters as Erbium Doped Fiber Amplifiers with...
Fiber Wireless (FiWi) networks constitute a very promising, cost-effective solution to cope with modern demanding services and applications in access networks. One of the most challenging objective lies in the design of a robust, efficient and effective bandwidth allocation. The design of such a Dynamic Bandwidth Allocation (DBA) scheme should take into account the large propagation delays between...
The Gigabit Passive Optical Networks (GPONs) are widely deployed in Europe these days. For example in the Czech Republic, telecommunication access networks will deploy GPONs in order to fulfill a minimal transmission speed 30 Mbps which is planned in 2020. Generally, GPONs are defined by the family of recommendations ITU-T G.984. Nevertheless, the recommendations ITU-T G.984 do not define the security...
In this paper experimental verification of optical fiber based parametric amplification has been studied over different modulation formats. Based on principle of parametric amplification, which is essentially a non linear phenomena, these fiber amplifiers offer discrete amplification along with greater use of bandwidth without any major compromise on usable gain and vice versa. We have demonstrated...
