Simultaneous bidirectional transfer of data and power supply over one fiber

This Bachelor’s Thesis deals with projecting and implementation of transmission systems using a single optical fibre for parallel bidirectional transmission of optical power and data signal. These systems include Polarization Division Multiplexing (PMD), Wave Division Multiplexing (WDM) and Time Division Multiplexing (TDM). The theoretical part of the thesis closely describes and specifies optical fibre, optical radiation sources and detectors as well as passive optical components suitable for transmission system implementation. Further, the thesis describes principles of individual transmission systems including a selection of particular optical and optoelectronic parts for the TDM and WDM transmission composition. Each chapter of the practical part of this document describes methods and processes used for individual measurements. First the individual parameters of individual optoelectronic and optical components of transmission systems are verified and characterized. This is followed by measuring the parameters of the composed TDM and WDM transmission systems such as optical loss, transmitted electric power efficiency, transfer speed etc. Finally, the possibility of outer optical signal detection on an integrated photodiode PIN of the laser diode is tested and verified, which could be used for both transmission and reception of data signal
