Precise Measuring Test Bed for Characterization of Mode Field Distribution in Different types of Multimode Fibers
(Zeithamlová Milena Ing. - Agentura Action M, 2019)
In this paper we present experimental results from
precise measurements of mode field distribution in various
commercial multimode (MM) fiber types. We characterize the
mode field distribution by the encircled flux (EF) ...
Optical Hybrid Fiber/Free-Space and 25 GHz Wireless Transmission using LTE M-QAM Signals

We experimentally demonstrate photonic millimetre wave signal generation and distribution over hybrid networks based on wired and wireless links. Optical frequency multiplication based on carrier-suppressed modulation has ...
On Optically Pre-amplified FSO-MISO Non-identical Links with Correlation: Experiment and Analysis
(American Institute of Physics and Magnetic Society of the IEEE, 2019)
In this paper, various link characteristics and bit
error rate (BER) performance of a free-space optical (FSO)
multiple-input-single-output (MISO) system with repetition cod-
ing (RC) is investigated both experimentally ...
M-QAM transmission over hybrid microwave photonic links at the K-band
(Optical Society of America, 2019)
Two experimental configurations of a hybrid K-band (25 GHz) microwave photonic link (MPL) are investigated for seamless broadband wireless access networks. Experimental configurations consist of optical fiber, free-space ...
Experimental analysis of a triple-hop relay-assisted FSO system with turbulence
(Elsevier Science Publishers B.V., 2019)
This paper outlines experimental investigation of the performance of the wireless optical network based on an all-optical triple-hop free space optical (FSO) communications employing amplify-and-forward relaying under the ...
Experimental all-optical relay-assisted FSO link with regeneration and forward scheme for ultra-short pulse transmission
(Optical Society of America, 2019)
This paper presents experimental results for an all-optical free-space optical (FSO) relay-assisted system by employing an all-optical regenerate and forward (AORF) scheme in order to increase the transmission link span. ...
Efficient Exploitation of Radio Frequency and Visible Light Communication Bands for D2D in Mobile Networks
(IEEE, 2019)
The concept of device-to-device (D2D) communication, combining common radio frequency (RF) and visible light communication (VLC), is seen as a feasible way how to cope with spectrum crunch in the RF domain and how to ...
